Reviews by Ace Bee

The build and sonic quality of Magni C4 and Modi C4 are way beyond their asking price of around 100 USD​

Verus Audio is a fresh new face from Indonesia in the posse of audiophile cable manufacturers. They started their journey in 2015 with bespoke cables for CAR AUDIO, HOME AUDIO, and PORTABLE AUDIO. Their USP is a unique tuning formula that seamlessly harmonizes with a diverse range of devices.

The Magni C4 and Modi C4 are from their Optimised Materials Cable series. Here they use the more conventional cable materials - copper, silver-plated copper, or pure silver. However, despite sounding very ordinary, it is the unique build quality that creates a differentiating performance.

Disclaimer: I received the cable as a free demo from Verus Audio for my impressions. But I would have gladly paid their full price if 1) I did not have other cables lying around unused and 2) I had a chance to audition them previously.

Design and Build​

Magni is made of ultra pure Oxygen-free Copper (OFC) in a Type-2 litz wire configuration, and Modi is made of Silver-Plated Oxygen-free Copper in Type-2 litz wire configuration - pretty straightforward.
C signifies its innovative coaxial design paired with a 4-braid shield - OFC Litz for Magni and Silver-plated OFC Litz for Modi.
4 is the number of strands in the cable. There is also a 6-strand version available at a slightly higher price.



The insulation of the cable is really exceptional. It is very soft and supple, while having a semi-transparent colour - blue for Modi and dark grey for Magni. There is minimal to no microphonic effect. The surface is smooth and shiny but not sticky. I have not come across such high-quality insulation at around 100 USD before.

One thing to note here - the strands are thicker than other regular cables because of the coaxial structure with different gauges of wires inside. The signal carrying wire is 28.7 AWG, whereas the shielding wire is 26.1 AWG - together the AWG of the cable becomes around 24.2, rather on the thicker side. In fact, the overall thickness of the cable is similar to a regular 8-strand cable.



The splitter, cinch, plug, and connector housings are made of aluminum. They are very lightweight with a minimalistic design, look and feel pretty neat.

The plug is Rhodium-plated.

Tech Inside​

While the ultra-pure Type-2 litz cables make sure the signals are passed through with minimum resistance, the 4-braid litz shield eliminates interference and crosstalk for a noise-free listening experience. Both of them combined produce a very refined listening experience.

Comfort​

Despite the somewhat bulky build for a 4-strand cable, they are surprisingly lighter than expected, although slightly heavier than other 4-strand cables, but also lighter than some 4-strand and mostly all 8-strand cables. I believe the lightweight aluminum accessories help keep the weight at a manageable level.

The earhooks are also correctly designed to secure the cable without squeezing the ears. Thus, despite the thick build, they are one of the most comfortable cables I have ever used.

IEM: Artpical Lucifer with Magni C4, 634EARS LOAK2-TX01 with Modi C4​

The first aspect that immediately stands out in both cables is the slightly darker and cleaner background. I assume this is the shielding effect - which acts as expected. It enhances the transparency and macrodynamics of both the iems by a bit.

The Artpical Lucifer is decidedly bright-sounding, albeit v-shaped overall. With the Magni C4, the upper-mid and treble brightness still shines through but seems to be controlled ever so slightly. The robust bass region is preserved well with no noticeable change. The lower midrange is adequately full and articulated. The boosted upper-mid sounds refined. The treble energy and extension are untouched as well with some added body in the treble notes.



The 634EARS LOAK2-TX01 is a similarly V-shaped iem that provides deep and powerful bass, a slightly pushed back but clear midrange, and vivid treble. The Modi C4 tightens the abundant bass presence and improves the textures a bit. As a result, the lower midrange presence becomes a tad bit more prominent. The upper-mid, being already plenty forward, sounds unbridled, but not piercing. The treble is brilliant, shimmering, well-extended, with a slightly improved note body and microdetails. It is an exquisite package.

Conclusion​

Both the Magni C4 and Modi C4 do not change the sound signature by any means. They just enhance it by adding a bit more body as well as cleaning up the background to provide a bit more transparency and macro & microdynamics. They provide a holistic improvement of the sound.

And not just the sound - they are by far the most ergonomic cables I have ever used. Despite how thick they look, they are surprisingly lighter than some 4-core cables of lesser girth. On top of that, they are, to my experience, the softest and most pliable cables. There is absolutely no memory effect, no springiness. There is minimal to no microphonic effect, and they do not tangle ever! They are smooth to the touch. This is absolutely the best insulation of a cable that currently exists in my opinion - For context, I have used cables multiple times costlier than them.

Verus Audio, somewhat surprisingly, offers a complete package at a very pocket-friendly budget - ergonomically the best, while enriching the sound in a comprehensive manner, with the classiest of looks. This is, frankly, everything one may wish for.

Small it may be, but big is its heart, and win it will you over​

Intime is a Japanese iem brand, originating from its parent company O2aid, a company specialised in developing piezoelectric devices. The CEO of O2aid created intime acoustic to produce earphones that provide great sound at a relatively lower price, primarily targeting the student segment who wanted to enjoy good sound but could not afford costly gear.

The products range from 50 USD to 200 USD in the current active line-up. There are other special releases and a flagship model costing around USD 460. The unique property of intime iems is that all the models have the same driver configuration, only the tuning differs along with slight changes in the driver materials - 1 full range DD + 1 Piezoelectric ceramic V.S.T (Vertically Supported Tweeter) for the higher frequencies + 1 HDSS (High Definition Sound Standard) for correcting distortions.

My introduction to them happened with Sho DD. The DD here stands for Duralumin Design, as the front housing of the iem was made of a material called Duralumin. The tuning was developed based on the flagship iem Sho. It was a very fun sound with heavy-hitting strong and deep bass, full-sounding midrange, and a bit polite but still clean highs. While I liked it initially, the lack of bite and sparkle in the highs ultimately broke the deal for me.

One year later, I saw the Miyabi MkII was introduced. I decided not to take a leap at them and just wait…but after a gap of two years, I thought oh well, let’s give it a shot. I was tired of the iems in the sub-$200 price range, did not want an over-ear configuration anymore, and a simple bullet-shaped design became more alluring.

Disclaimer: This is where www.gdaudio.hk came to my rescue. They provided me with a very nice discounted price on the Miyabi MkII in exchange for a fair review, and I bought it.

Design and Build​

Like most of the intime iems, the Miyabi MkII is bullet-shaped, and made up of two separate front and rear housings joined in the middle - the front being metal and the rear being resin. Now, in the OG Miyabi, brass was used for the front housing, but it reportedly developed oxidation issues and users often found green deposits in the nozzle. In the MkII model, the housing is made from anodized Titanium, so this issue is eliminated.

The rear resin housing is semi-transparent and provides a glimpse of the internal - namely the DD and the HDSS is visible. The mmcx connector is mounted such that it can be worn in a straight-down position, but it can also be worn over the ear should one wish so. The nozzle in the front housing is situated straight and not at an angle.

The overall build is quite small, very compact, and very solid. This is a very well-built iem and can take a fair share of beating. Mine fell to a hard floor from around waist height, took a dunk in water - and yet is performing flawlessly. (No I do not mishandle my iems, those were accidents.)

Tech Inside​

I have always loved the sound of a full-range DD, the primary driver used in intime iems. The Miyabi MkII’s DD has a graphene diaphragm. It was specifically developed to work with the VST with as low distortion as possible.

Their proprietary technology, the Piezoelectric ceramic V.S.T (Vertically Supported Tweeter), fascinated me. I was no stranger to piezoelectric drivers, but the ones I heard sounded either metallic and sibilant or dull. Intime claimed to address this by using a nickel alloy material in the diaphragm in conjunction with ceramic elements to provide a clear and sparkling treble that is not uncomfortably sharp or piercing.

In Miyabi MkII the 3rd generation VST-2 tweeter is used, which has improved sensitivity in the ultra-high range.

The last part of the driver configuration is the HDSS, or High Definition Sound Standard. TBI Audio System LLC developed this technology. It helps to reduce the distortion in the sound and thereby assists in producing a gentle sound with a wide soundstage. In Miyabi MkII the HDSS technology is 4th generation, with improved acoustic correction effect over the previous generation.

The DD and the VST are coaxially mounted, whereas the HDSS is at the back of the housing.

Cable​

The cable is developed by Intime in-house as well. It is a hybrid OFC+Silver plated OFC cable. I love its simple construction, and the soft and pliable yet premium-feeling silicone sleeve. There is minimal microphonics so that is another plus. The right-angled plug makes it easier to use with the phone in the pocket.

Comfort​

Bullet size ensures a fuss-free and comfortable fit. The lightweight cable helps to keep it in place. Really, the comfortable and easy fit is one of the most positive point of this iem that keeps me hooked onto it. It is just so easy to plug into my ears and get immersed into musical nirvana.

I was very pleasantly surprised by the Miyabi MkII's soulful sound. The warm-neutral tonality, thick yet controlled bass, full midrange, sparkling and well-extended treble, and an effortless yet very good detail reproduction make the whole presentation balanced and highly captivating.

It does not sound overzealous and still gets you hooked in no time. One of the rarest combinations where technicalities are not compromised in the way of enhancing the richness. Suffice to say I am completely smitten by them.

Bass​

The Miyabi MkII has a deep and slightly thick bass. However, natural decay helps to keep things clean and contained. The subbass goes deep with a controlled amount of volume. The textures are prominent but not super fine - the notes are slightly rounded. The midbass has a fair amount of slam that gets you grooving without encroaching on the space.

The bass hits a nice balance between a robust presence and moderate speed that makes it sound very fun and yet not linger any longer than necessary. The notes are nicely defined, slightly on the thicker side but not bloated at all.

Midrange​

The midrange is the sweet spot of this iem. It is very full and sounds organic. The lower midrange has a nice luscious presence. The upper midrange has an energetic presence without ever becoming shouty. Both male and female vocals benefit from this - they sound alive, and vibrant without compromising the natural definition. The instruments are lifelike and have a nice bite.

The note definition is superb - it is full-bodied and the details around the edges are accurately reproduced while sibilance is deftly toned down. This is the perfect balance between musical and technical portrayals.

Treble​

The treble is unique. The piezo-ceramic VST handles it, and it sounds like an enhanced DD treble. The timbre is not off by any means. The mid-treble is forward and has plenty of energy but no piercing peaks. The upper treble extends nicely, but is comparatively slightly less energetic, and yet commands a noticeable presence.

The notes are nicely defined but could do with slightly more body. Despite the slightly smoother presentation, the details are very apparent.

Technicalities​

I found the Miyabi MkII has fairly nice technical prowess in its price bracket. The stage may not be very big, but it is very well-constructed. The width is pretty nice and extends slightly beyond the ears. The height and depth of the stage are decent too, creating a well-rounded soundstage.

The distinct separation and meticulous layering of the notes make the imaging reasonably precise.

Comparisons​

Vs. Kiwi Ears KE4​

The Kiwi Ears KE4 is a hybrid consisting of 2 DD and 2BA drivers. The dual custom 10mm DD are used in isobaric configuration as a subwoofer, the two RAD 33518 BA drivers take care of full range and high frequency.

The KE4 is an over-the-ear configuration, relatively small in size when compared to other similar over-the-ear iems, and very comfortable to wear - it almost disappears inside the ears.

Compared to Miyabi MkII, it has a similarly extended subbass and slightly lesser impactful midbass. The bass is slightly leaner as well, giving way to more space. However, it does not sound as solid and engaging as Miyabi Mkii.
The lower midrange is slightly leaner as well, so does not feel so full. On the other hand, the upper midrange and treble feels a bit more ethereal with an added dose of energy.
The treble is very nicely mastered - brilliant, extended, and exquisitely detailed but not spicy or in your face. In comparison, Miyabi MkII’s treble feels slightly subdued.

The KE4 has a bit more open presentation compared to Miyabi MkII. The separation is noticeably improved by a step. While the soundstage expanse seems similar across both iems, the KE4 surely has slightly better layering and imaging.

Both the iems have very refined tuning with slight variances here and there. Miyabi MkII is a bit more bold while KE4 sounds a bit more refined.

Vs. iBasso 3T-154​

The iBasso 3T-154 has a 15.4mm Dynamic driver with 3 Tesla magnetic flux in its heart and an Aluminium shell as the body. The size is huge and the shape is a bit weird, as a result the wearing comfort and fit are noticeably less than Miyabi MkII.

Soundwise, Miyabi MkII has a thicker and more dynamic sound with significantly more prominent details. The technicalities are better in all aspects except the soundstage expansion and airiness - which felt a tad bit better on 3T-154.

Miyabi MkII has a deeper and fuller bass with more textures, a fuller and more detailed midrange, and more energetic treble with better extension and note definition. While the stage feels not so spacious due to the thicker notes, it is still very nice. Separation is similar and imaging seems slightly better on Miyabi MkII.

Vs. Juzear 41T​

The Juzear 41T has 1 DD and 4 BA drivers. The 10mm DD is for low, 2 Sonion BA drivers for mids, and 2 customised BA drivers for highs. It has an over-the-ear configuration and is fairly comfortable to wear.

It has a clean and transparent sound, with a prominent yet well-balanced treble that extends smoothly without exaggeration. It offers a spacious presentation, featuring crisp, sibilance-free notes and clear, defined details. The soundstage has more height and depth, allowing background instruments to be distinctly heard. Overall, the sound is slightly leaner, with enhanced clarity and more detailed treble.

However, The bass lacks body and power in comparison, while the lower mids can sound somewhat thin, making male vocals feel lean. The overall sound is rather laid-back, with a safe tuning that lacks dynamic energy. The upper mids also lack the engagement and vibrancy needed for a more lively listening experience.

Conclusion​

I round off my rating to the nearest value with a 0.5 step. Here, the total rating came to 4.72, which was rounded down to 4.5. The above chart is an objective summary of my complete impressions of it from my subjective point of view.

To be very honest, I simply cannot live without the Miyabi MkII. It practically lives in my pocket. The amazingly full and vibrant sound along with the exquisite wearing comfort have made it a necessary travel companion for me. It is very rare to have a bullet-shaped iem sound this good. But somehow, Intime has pulled it off.

Intime Miyabi MkII breathes life and soul into the music. Of course, not like the kilobuck models, but frankly, I have not felt so one with the music with another iem in this same price bracket. It may be small in size, but its rich sound provides a uniquely fulfilling experience that I did not experience from any other iems below 200 USD. This is my most used iem since I have got them in my hands, and it lives in my pocket.

Rich sound, elegant looks, and practical ergonomics - all rolled into one​

iBasso is a highly respected brand in the audiophile community. They have been producing consistently well-acclaimed sources in the portable category for a long time. Their offerings range from budget to premium, with almost every price bracket covered in between.

They started their dongle USB DAC/Amp line with DC03 and DC04. I owned the DC04PRO that came out last year and loved its refined and smooth tuning. I currently own the DX260 as my main source. Hence, I decided to give the DC07PRO a try as well.

Note: I purchased the DC07PRO from Bloom Audio with a slight reviewer’s discount.

Packaging​

The packaging of DC07PRO is compact and very premium looking, with a shiny blue box and bold lettering. Inside, the device, accessories, and miscellaneous documents are stored in designated foam cutouts.

In the box​

• DC07PRO
• Type-c to type-c cable
• Type-c to lightning cable
• Type-c to USB-a adaptor

Design​

The DC07PRO looks absolutely gorgeous - the CNC machined sandblasted finish aluminium body feels minimal yet elegant with subtle curves and grooves. This medium-sized dongle with a mere 23g weight is perfect for pocket carry. The silver colour has a nice contrast with the black OLED screen. The name of the device is written on the bottom with the iBasso slogan “In Pursuit of Perfection” behind a tempered glass panel.

The SE 3.5mm and balanced 4.4mm headphone sockets are located side by side at one end, and the opposite end houses the type-c port. The volume wheel is placed on the side near the top in a groove.

The volume knob is a welcome departure from the mundane volume buttons - easier to operate (though opinions might differ), and feels quite luxurious. There is a slight bit of play but the performance is not affected. Not a single step gets missed while changing volume - an issue I often encountered in the past with DAPs.

Internals​

The DC07PRO has in its heart a quad-array of Cirrus Logic CS43131 DAC chips. These chips are being widely used for sources from budget to high-end sources. iBasso has implemented their in-house developed FPGA technology and KDS Femtosecond Oscillator around them for more enhanced performance.

The result is a higher power, improved dynamic range, and lower noise floor.

OLED Display​

The 0.96 inch OLED display is fairly big, making the information fairly legible and operation easier.

Multifunction Volume Knob​

The volume knob also acts as a multifunction button. With a long press the settings can be accessed, which are displayed in the OLED display. Then with a combination of press and rotation, the settings can be altered at will.

Phone Application​

iBasso has a dedicated phone application available only on the android platform for their USB DAC/Amp - the iBasso UAC app. When given control of the device to this app, the controls of the dongle will be at your fingertips rather than fiddling with the dongle.

Battery consumption​

The DC07PRO consumed only 3% of my phone’s (Oppo Reno7 5G) battery (4500mAh) over 15 min, playing on-board 16/44 FLAC files, connected to a pair of 32ohm transducer via the balanced output in medium gain. iBasso’s claim of “Exceptional Power Efficiency (up to 94%)” despite the high power output of 430mW holds true.

Sound​

Settings: Mid Gain, NOS filter
IEM/Earbud: Shanling MG800, Technics EAH-TZ700, Alpha Omega Ra, LREY Aurora

The DC07PRO produces a very well-behaved sound. It handles all the frequencies in a very even-handed manner. There is very little colouration involved. The tonality is mostly neutral with a hint of warmth. The DC07PRO lets the music play in its truest form without any significant alteration.

Bass​

The subbass is deep and textures are quite apparent, but it does not feel pervasive. The decay is natural. The midbass slams are tight, full-bodied with just enough impact to feel the fun. The power is expertly maintained at an enjoyable level that does not muddy the midrange.

Midrange​

The midrange feels very natural, there is no sudden spike in energy anywhere. Both the lower midrange and upper midrange sounds sufficiently full. Despite the somewhat calm tuning, there is plenty of energy to keep you engaged. The slight hint of warmth adds to the musicality. The details are effortlessly reproduced without sounding forced.

Instruments, male and female vocals - everything sounds reasonably crisp, yet slightly smooth. They are positioned neither too forward nor too recessed, just right.

Treble​

The treble section sounds smooth yet detailed and well-extended. The lower treble has plenty of energy to sound natural while avoiding the sibilant peaks. The upper treble extends well but is relatively less energetic. Together, the treble has a sparkling and clear presence while ensuring a fatigue-free listening experience.

Technicalities​

The DC07PRO projects the sound over a pretty wide and spacious soundstage with decent height and above-average depth. I wished it had slightly more depth, making the presentation more holographic. The separation is very well-done.

While the microdynamics is decent enough, the macrodynamics has room for improvement. I expected it to be a bit more dynamic sounding given the high dynamic range. The background is clean but could have been a bit darker.

The smooth yet crisp note definition feels very refined. They feel effortlessly detailed without sounding edgy or uncomfortably shouty.

Check out my test tracks: sub-bass, midbass, male vocals, female vocals, instruments, treble

Comparison​

Vs. Moondrop Moonriver2 Ti​

The Moondrop Moonriver2 Ti is made of Titanium shell with a glass bottom and driven by dual CS43198 DAC. It does not have any display, just an independent volume button. It is slightly thicker and significantly heavier than the DC07PRO. The curved body has a distinct kind of smooth charm.

The Moondrop Link app is abysmal in quality compared to the iBasso UAC app. More often than not it failed to detect the device and hence I was unable to access the full control of the device, namely the filter settings.

In sound, the MR2 Ti has a more V-shaped sound profile. The sound is slightly more dynamic, with more pronounced bass and treble energy. The midrange is slightly pushed back in comparison. The biggest difference is in the notes - they feel slightly thinner in comparison, and not as natural. The background feels sightly darker and stage is slightly deeper. However, the DC07PRO sounds more natural and matured.

Vs. Luxury & Precision W2 Ultra​

The L&P W2 Ultra is driven by dual CS43131 DAC, and is characterised by its huge power output of 800mW @ 32ohm. It is very slightly bigger in size with almost the same weight. Both of them have ALPS volume knob that works flawlessly. The LED on W2U is smaller but works equally fine.

Soundwise the W2U and DC07PRO feel very similar in tonality. Though, the former is decidedly a better performer. The sound of W2U is more dynamic, more transparent, better resolving, more three-dimensional, yet not peaky or sibilant at any point. Just an altogether better performer for around 120 USD more price.

Conclusion​

iBasso has truly hit it out of the park with the DC07PRO. In the below 200 USD segment such a refined tuning coupled with the classy look and premium build is a first. The well-built android app only elevates the overall snappy user experience even more.

Granted, it is not perfect. It left me slightly dissatisfied in the fields of macrodynamics and stage depth. However, the overall nearly uncoloured, very natural, competitively technical and yet comfortable tuning makes it unparalleled and a default recommendation under 200 USD.

Introduction​

Aful does not need any more introduction by now, as they have established themselves as a competent brand creating beautiful sound through constant innovations. Till now, they have been creating mostly BA-based transducers, and with the SnowyNight they finally have ventured into the source segment.

Disclaimer: I received the Aful SnowyNight as a part of review tour. I will not retain this unit.

Packaging​

The SnowyNight is housed in a small and compact box.

In the box​

• SnowyNight
• Nylon sheathed type-c to lightning cable

Design​

The SnowyNight has a really nice design and build. Simple rectangular design, with just the right amount of aesthetics added via the three-pronged snowflake patterns to make it visually pleasing. The edges are not sharp. Another positive aspect is the compact size - I really do not like extra long or wide dongles. SnowyNight has just the right proportion.

The end where the 3.5mm and 4.4mm jacks are housed is a bit thicker than the rest of the part. In the snowflake pattern, an LED is hidden at the center right beneath a snowflake - looks classy.

The volume control buttons are located on a side. It is an independent volume control - much appreciated.

Aful has also selected a nice material for the cable - 6N OCC. Whether it has any actual impact on the sound - I was unable to determine that as I had to use a different cable, since the supplied cable was lightning and I do not have any apple source. The cable looks quite premium as well.

Internals​

The SnowyNight has dual Cirrus Logic CS43198 DAC embedded inside, the flagship one. It is also declared to utilise an advanced USB lossless transmission for enhanced performance.

SnowyNight Sound​

I used the SnowyNight with aftermarket type-c cable and Oriveti OH700VB for evaluation.

Click to expand...

The SnowyNight has a really refined and matured sound signature. The tonality is largely neutral with a slight hint of warmth to make the presentation comfortable and natural. Aful has struck a wonderful balance between the musicality and technicalities here.

The whole spectrum is handled in a very uniform and even manner. Nothing is emphasized over others, and yet the overall presentation is not boring. It is kept dynamic enough to grab the listener's attention.

The bass goes deep but does not have any added body here. The midrange is smooth and transparent. The treble is well-extended and has a very decent amount of energy. The notes are crisp but the edges are smooth, providing a comfortable but detailed presentation.

The soundstage has very good width, decent height and depth. The depth feels a bit less compared to the width so it might come across as a bit flat, but nevertheless, that is not a big caveat. The imaging is precise.

Comparison​

Vs. Fiio KA5​

For comparison, I have chosen another CS43198 powered dongle, the Fiio KA5 (currently my daily carry).

Not commenting on output as it is more or less comparable. Perhaps the SnowyNight is slightly more powerful than the KA5, but marginal difference.

The KA5 has a music play/pause button, along with a plethora of other functions - filter selection, volume step selection, UAC1.0 and 2.0 toggle, display rotation, S/PDIF On/Off, High and Low gain, etc. The small LED display further helps in providing the necessary information. The SnowyNight is much inferior in this, having just an LED light and High/Low gain, nothing else.

The KA5 sounds slightly more dynamic and slightly warmer. but the stage feels slightly more narrow, albeit with noticeably greater depth. It is also lighter and more compact compared to the SnowyNight. The SnowyNight is no slouch though, - the resolution and imaging seem to be at par with the KA5, and the more neutral tonality is a welcome change.

Conclusion​

The Aful SnowyNight is a very morally correct source. It is like a model student - nobody can pick out any bad qualities of it, but it is also not fun in parties either. It is very hard not to like it, and yet after a while the heart will crave for something more fun. However, those who are looking for a comfortable source with no major drawbacks - SnowyNight is perfect for them. Smooth yet technical, Neutral yet enjoyable - the unique presentation of it is sure to win hearts. An altogether very mature performance, hats off to Aful for that.

The Oriveti OD100 surprise with their highly dynamic, crystal clear, and wide-open presentation.​

Thank you to Oriveti for providing the OD100 for review.

Oriveti had a fair market presence back in the day. They had some nice hybrid models like OH300 and OH500 that were somewhat positively received by the audiophile community. Some years back they released some full BA iems, O400, O800, and a variable bass option of O800 named OV800.

Only recently they came out with some single DD and premium hybrid models. Among them is their first budget single DD offering - the OD100.

Design and Build​

The OD100 get full marks from me in terms of design and build. The cylindrical shape body has a CNC milled full metal build which feels sturdy and yet surprisingly light (only 4g). The size is quite small so it never becomes uncomfortable. The spiral pattern on the backplate and the etched brand and model names add a premium touch.

Although it seems to be a bullet style, the nozzle is not straight, it is placed at an angle - which makes them difficult to wear cable down and makes them invariably fit for only over-the-ear wearing.

Cable​

The cable of the OD100 feels quite premium. It is a 4-strand cable, presumably made of silver-plated oxygen-free copper from the visual depiction. The cable is of the right thickness - not too thin to feel cheap, not too thick to become uncomfortable. Overall it is very soft and pliable with no memory effect, and minimum tangle-prone. The aluminum hardwares are properly branded, well-made, and lightweight.

Comfort​

The small cylindrical shaped body along with the angled nozzle is very ergonomic and ensures a comfortable and easy fit. In my ears they are totally a flush fit depending on the eartips used. There are no oddly protruding edges that might cause pain. The 2-pin connectors fit snugly and tightly.

The cable however has tight ear hooks that cause pain after a while for my ears. I had to partially remove them for a more comfortable fit.

Under the Hood​

The OD100 employ a single high-quality 9.2mm DLC (Diamond-like carbon) dynamic driver to deliver the sound.

How Do the OD100 Sound?​

The OD100 have a w-shaped sound. Bass, midrange, and treble - all three of them sound appropriately boosted to create a very lively and fun sound. Tonality is warm and balanced, which makes it all the more enjoyable.

I tested the OD100 with Hiby R3 II and Tanchjim Space Lite, with stock narrow and long bore eartips.

Bass​

The midbass slams quite hard and fast. The notes are thick and very well-textured. The subbass is slightly rolled-off so that physical reverberation cannot be felt to that degree. Still, the subbass is quite decently powerful and can be heard clearly. The textures are very prominent.

Oriveti has gone for a bass that is strong yet clean. The slight subbass roll-off helps to make the stage a bit clearer. The midbass punch enhances the fun and macro-dynamics. The wonderfully sculpted notes bring refinement to the mix. Altogether, this is a very unique tuning pulled off quite skillfully.

Midrange​

This is the real delight. The midrange is forward, full, transparent, highly detailed, and vibrant, with crisp notes. The life of music is in its midrange, and the OD100 provides a very rich one.

The lower midrange puts a smile on my face. This area sounds organic yet very nicely resolving. The male vocals have a beautiful throaty tone with excellent edge definition. The same goes for string instruments - acoustic guitars and cellos sound natural, full-bodied, and sometimes appropriately gritty.

The upper midrange has plenty of energy to bring out the soul. Despite the energy, there is a slight dip in the 4-6kHz that keeps the sibilance mostly in check. Hence the female vocals and the violins flow freely, and the electric guitars scream with no restraints. The slight warmth along with the unbridled energy brings out the emotion in its entirety.

Treble​

The excellence of the midrange is rightly complemented by a similarly exhilarating treble region.

Frankly, I am at a loss of words. This region sounds so effortlessly detailed that it takes my breath away. The lower treble emphasis is just the perfect amount where it sits right behind the midrange but not any further. The cymbal strikes are strikingly clear but never feel pushed forward. The notes feel tactile and highly articulated.

The upper treble is another level of delicacy. It is very well extended and superbly resolving. Even the finest amount of details are brought forward without any uncomfortable peak. The airy presentation is moderated by a controlled amount of energy and enhanced by distinctly defined notes.

The treble here in my opinion is at the pinnacle of refinement.

Soundstage, imaging, and details​

The soundstage is very wide and creates a nice out-of-the-head presentation. The depth and height are good as well, but not proportionate with the width. Hence, the stage is very enveloping from both sides, but not spherical.

The forward presentation slightly compromises the depth, but the first-class layering makes up for it. Imaging is pretty good - I never felt anything is blurry. The separation is very good with each note having its own field to play.

Bar the subbass, the whole spectrum has very delicately designed notes with a high degree of palpability. There is an excellent balance between the macro and micro-dynamics. The sound is abundantly exuberant all the while carefully extracting the finer details.

Comparisons​

Vs. Hiby Hela​

The Hiby Hela are an entry-level single DD offering from Hiby. The shells are the classic semi-custom shape, semi-transparent resin made, and of dark brown color. They have 10mm PU+PEEK diaphragm and dual chamber dynamic drivers powered by dual magnets.

Comfortwise both are identical. Even though the shells of Hela are slightly larger than the OD100, the shape is such that it provides a very comfortable fit. Although the OD100’s full metal build feels more sturdy than the Hela.

The Hela have a more pronounced V-shaped sound compared to the OD100. The subbass is deeper, the midbass is almost similar (maybe slightly bolder), and the notes are thicker. The midrange is a bit pushed back compared to OD100, and sounds slightly thinner and edgier. The treble is a bit more forward with sharper notes. The presentation is a tiny bit more holographic.

The OD100 feel more mature in comparison. The midrange feels fuller and more organic. The treble is more controlled yet with a similar technical performance. The midbass is dynamic and the subbass supports it well. The presentation is sufficiently spacious. Nothing to complain really.

Who Should Buy This?​

Anyone who is interested in dynamic yet refined sound from an easy-to-drive pair of earphones should buy this. They should also have a tolerance for slightly bright midrange.

Final Thoughts​

The Oriveti OD100 is the surprise of the year for me, especially considering they are priced at around 70 USD. Very rarely a iem comes around with good sound paired with classy looks - and OD100 is exactly the same. The sturdy and compact metal shells scream quality, along with the well-built cable and carrying case.

And then when you put them into your ears, you are greeted with a bold and beautiful sound, that shakes your core and makes you tap your foot along with the rhythm. The strong and dynamic bass starts the party, the lush and charming midrange woos the heart, and the phenomenally exhilarating treble gives an exquisite finishing touch while maintaining an excellent separation and immersive stage.

I love the OD100. They are my daily carry iems when I want a casual listen straight from my phone without wanting to compromise on the quality. Their robust build ensures safety while being carried in pockets while the light weight means zero ear fatigue. Frankly, I cannot ask for anything more for their asking price.

Company Overview​

Oriveti was founded in 2015. The founders had years of engineering and design experience in the earphone industry. They are based out of Hong Kong.

Their initial releases were more or less warmly received by the audiophiles. Their all BA offerings like O800, O400, and OV800 garnered numerous praises as well.

Introduction​

Tanchjim, a well-known audio brand from China, has a strong presence in the ChiFi audio market. They're known for their unique sound signature that's neutral, smooth, and engaging. Following the success of their Zero model, which had a great neutral sound, they've introduced the One. The Tanchjim ONE Earphones (Without Microphone) is their latest offering. I reviewed the Ola earlier, which I found very unique and quite worthy of its price. In this review, we'll explore the One’s sound quality, design, and comfort.

Disclaimer​

I was sent this IEM by ForHiFi Store for an honest review. You can purchase this from the following link:
https://www.aliexpress.us/item/3256805717722491.html?gatewayAdapt=glo2usa4itemAdapt

Specifications​

Driver Unit: 10mm Dynamic Driver
Sensitivity: 126dB
Impedance: 16Ω
Frequency Range: 7Hz-45kHz
Connector: 0.78mm 2 Pin
Plug: 3.5mm/Type-C (DSP Variant)

In the Box​

The Tanchjim One comes with a simple box which I find is the standard philosophy of all of their gears - be it IEM or source. The minimalistic design of the packaging is attractive. In the box the following can be found:

• One earphones
• DSP Cable
• 3.5mm cable with mic (extra for review)
• 1 set of narrow bore eartips
• 1 set of wide bore eartips
• Branded carrying pouch
• Literatures

The cable is really good. Soft, pliable, and absolutely no microphonics. Mic performance is quite good as well.

Design and Fit​

The earphones are made of two parts - the front housing is made of ABS plastic and the back housing is made of Aluminium, with the Tanchjim logo and One etched on either side. The transparent shells display the clean innards and the DD. The angled nozzles and the very lightweight design provide a secure fit.

Sound​

The TANCHJIM ONE Earphones offer a well-balanced sound profile that will please both new and seasoned audiophiles. The tuning is quite refined for its price range. It has a distinct V-shaped sound with the stock 3.5mm cable but does not sound overly dark or bright at any point.

Bass​

The bass on the TANCHJIM ONE is well-bodied and impactful. It maintains a distinct presence without overwhelming the rest of the spectrum. However, there still is a slight midbass bloom that I can detect. It adds to the fun rather than muddying the stage. The subbass reaches really deep but does not sound bloated or overly slow. The textures in the bass notes are pretty fine. The tastefully powerful bass ensures listening comfort and avoids blending into the midrange.

Midrange​

The midrange is where the TANCHJIM ONE truly excels. It offers a very pleasantly natural tonality in the lower midrange that places you right in front of the artist. The instruments have quite enjoyable crunch and bite with the correct amount of note weight. The textures and details also surprised me.
There is a slight but noticeable hint of harshness or sharpness in the upper midrange, making it sound a bit metallic and spicy. This becomes evident in mostly the coarse male and energetic female vocals. This throws the overall tonal balance slightly off, but nothing severely objectionable. Apart from that the upper midrange sounds quite pleasant.

Treble​

The lower treble in the TANCHJIM ONE is decently energetic. It has a very clear and slightly forward presence. The upper treble is also very prominent in the mix and sounds airy. Notes seem to have a proper body, tonality is neutral. On a handful of tracks, the lower treble may sound slightly spicy but still retains the tonal balance.

Technicalities​

While not very large, the soundstage is very well-rounded with very nicely proportionate width, depth, and height. The overall presentation is reasonably clean. Imaging is good.
The notes are well-bodied and crisp, despite having an overall smooth tonality (except the upper-mids). Details produced are exceeding expectations in this price range, to be honest. Simply put - the technicalities are more than enough one can expect for the price.

DSP Vs. 3.5mm​

The main differences I noticed between the two are that the bass is livelier in the sub-bass and better controlled in the midbass, making the mid-range clearer and more distinct. The treble also sounds a bit crisper.
The vocals sound more pronounced with better perceptible details and instruments sound more vibrant. Female vocals have a livelier, lighter response, and the midrange sounds more spacious and more precise. The lower mid-range has a more transparent, expressive quality.
Technically, the details seem to be a bit more prominent, and the imaging seems clearer and more defined.

Conclusion​

The Tanchjim One is an outstanding IEM for the price. Discounting the slightly metallic spiciness in the upper-mid, the rest of the sound is very pleasant for general on-the-go casual listening. The addition of mic makes it all the more desirable. This is a very capable introductory offering from Tanchjim, showcasing what they are capable of doing in higher price brackets. Newbie audiophiles who are just trying to take an entry into the hobby but unsure of what to get - this is a great start. I definitely recommend them.

Introduction​

BQEYZ has been a long-standing player by now, and their offerings have continued to impress audiophiles around the world. They introduced the Winter as the fourth and the last offering in their seasonal series of IEMs (Summer, Autumn, Spring, and Winter). I have heard the Autumn and honestly liked it really. You can find it here.

The Winter had a pretty unique driver combination - one full-range DD with a Bone Conduction Driver. Winter Ultra is a retuned and improved version of the same, designed as a collaboration project between Angel Ears and BQEYZ. The cable and the tuning both are improved.

Disclaimer​

I received the Winter Ultra as a review tour unit from Hifigo. This is a loaner unit and not a keeper. Here is the product link: https://hifigo.com/products/bqeyz-winter-ultra

Design, Build Quality, and Accessories​

When you look at the original Winter IEMs and compare them to the new Winter Ultra, you'll notice some differences. The Winter Ultra has a special filter that makes the low-pitched sounds even better. The pair now sounds more even compared to the original version. There's a smaller peak in the sound around 5kHz, which makes the sound smoother and cleaner. The eartips that come with it are balanced, so you can hear things clearly. The cable that comes with it is better now, made from high-quality materials that can be changed around. And if you like cool colors, you'll be happy to know that the Winter Ultra comes in a beautiful blue color.

The Winter Ultra has a nice curved design on the front cover and a shape that fits well in my ears. There's a silver line on the front cover that matches the deep blue color of the shells. The BQEYZ Winter Ultra is actually the brand's top model right now, and it's made to be just like that. The parts inside are made of metal, and the color looks really fancy and high-quality.

It has two kinds of drivers inside: special 11.6mm PZT bone conduction drivers and 12mm Dual cavity PAR dynamic drivers. The dynamic driver takes care of the whole frequency, whereas the PZT driver enhances the treble region.

The IEM comes with a high-purity single-crystal copper silver-plated cable with swappable termination plugs - 3.5mm and 4.4mm. It's not heavy when you hold it, but it feels really nice and high-quality. The IEMs also have a case for carrying them, a brush for cleaning, and nine sets of eartips in three kinds (Atmosphere, Reference, and Balanced) and three sizes (Small, Medium, and Large).

I used the Winter Ultra with Fosi Audio DS2, and Tempotec V6.

Sound​

The Winter Ultra has above-average macrodynamics, clear highs, and impactful bass. The midrange is smooth and clear. Overall these have an excellently engaging sound profile.

The low end is fun yet controlled. The midbass slams well, subbass goes deep and rumbles fine. But everything is under control. There is no overabundance of power here. Midbass slams are a little bit more highlighted than the subbass rumble. The decay is pretty natural as well - does not feel too slow or too snappy. It injects just the right amount of energy to keep things lively.



The midrange is slightly behind the bass, however, it is not particularly V-shaped. The lower midrange stands clear and prominent. They sound sweet and well-textured - both the male and female vocals. The instruments have a focused presentation - the notes are crisp but not peaky. This region is smooth but is cleanly recreated. String instruments sound especially delightful - both acoustic and electric alike.



The treble is a really nice sparkle and vividness, without being piercing. The lower treble has a distinct forwardness that adds spice to the music. The upper treble extension is above average. There is a hint of sibilance but does not get very uncomfortable. The details are easily noticeable, but the notes are not particularly edgy. I believe this is the working of the PZT Bone Conduction Driver - I have to say, very deftly implemented.



The soundstage has above-average width and depth, with average height. But what won me over is the very clean yet smooth presentation of the sound. Layering and imaging are above average. It is mostly an intimate presentation. The slightly warm tilt and the cohesiveness of the tuning make it extremely pleasing to the ears.

Conclusion​

BQEYZ has made a really attractive iem with Winter ultra, consisting of a well-rounded performance altogether. For its price point, there are many more that can surpass it in technical chops but cannot match in terms of providing musical engagement. While I crave a bit more energy in the sound signature, and a bit more bite in the notes, I do admit for those who want a slightly more laid-back yet crisp sound - Winter Ultra will satisfy them without a doubt.

The implementation of the two types of drivers are done such exquisitely that both of their individual contribution merges very cohesively. Another point to note is the extreme comfort it offers. There is no uncomfortable pressure build-up, and yet they feel quite secure in place. The stock eartips are quite nice for varied preferences.

Review: Simgot EW200 Maze – Nearly Flawless​

The Simgot EW200 sound practically perfect, with unprecedented finesse at their low price point.​

Introduction​

Well, by now RIkubuds needs no new introduction. But for those that are not familiar with them, let me tell you a bit about the man behind them - @RikudouGoku . He is a beloved and respected individual in the audiophile community. A quite competent reviewer and overall a very nice person. Rikubuds is his venture into the earbuds world.

I was not a very big fan of earbuds, to be honest. The fit sometimes gave me pain in the ears and the lack of sealing made the ambient noise a bit intrusive into the music. However, after owning and enjoying multiple iems, I got curious enough, and reasoned with myself that it will be same as listening music through speakers, which I enjoy despite the presence of ambient noise. So I got something else, and then thought of getting the Rider 1 as well.

Specification​

Packaging, Design, & Fit​

Rikubuds comes in a very spartan packaging. Just a cheap small carrying case, housing the earbuds, spare foam covers of two different colours (black and blue), and the class card.

While making the product page, I have not included a photo of the same because the appearance of Rider 1 can be modded slightly by choosing the mx500 shell colour and cable colour. Remember, just the colour, as the inside is same - silver plated copper. I chose a dark blue shell (red being the other option) with matching blue/white cable. Looks stunning, as you can see below. Termination is 3.5 mm single ended.



Initially I had to struggle with the fit a bit, my ears took time to accustom to it and I went through slight pain on the concha. However, to search for a better fit and to get a bit more bass, I chose to put two foam covers back to back on the buds, and voila! Now it is much pleasant to wear with a slight more bass boost. Presently using them with Hiegi foams, better clarity over double foam while preserving the bass boost.

Disclaimer: I bought it at full price (50 Euro + 16 Euro shipping). I was not obliged to write a review but I love it so very much I have decided to write my opinions about them. I believe I am the first one from India to be an owner of a Rikubuds earbud.

Sound​

Let me tell you this - I was NOT prepared for the sound that came out of Rider 1. It immediately felt as if I was swimming in a world full of music. The projection was well beyond the boundaries of my head - very similar to having a speaker arrangement around my head at a slight distance. I was lost in a musical euphoria.

Tonality wise it can be classified as warm neutral. Previously it was neutral with a hint of warmth, but putting two foam covers back to back has introduced a hair bit more warmth.

Bass surprised me with its slam in the midbass. It is not that I have not experienced the same with other earbuds before, but they did not come with such awesome transparency. Now, coming from IEMs, the bass definitely did not sound as powerful or visceral in the beginning, but once my ears got used to it, I actually found it sufficiently full in most occasions. The midbass has a really nice punch and a volume that feels just right. Subbass extension is not bad either, but ultimately it does not get very tactile. Still, there is a very nice weight in the whole bass region that makes it sound natural, and the textures are wonderfully reproduced. If I have to nitpick, the decay sometimes seems to be a bit faster than my preference.

The drums in Metallica - Enter Sandman and The Four Horsemen sound quite impactful and fun. But the bass drums in Battlestar Galactica Season 2 OST - Prelude To War does not thunder to their best capacity, they do still sound quite punchy, but not as full because of the slight compromise in the subbass and the decay. The bassline of Massive Attack - Angel has enough pressure

Midrange took my breath away. I did not expect such effortlessly natural mids with outstanding separation, textures, a fair bit of crunchiness but completely devoid of sharpness. This is a refinement unexperienced beforehand. Yeah they are not overly juicy and thick, but still sufficiently organic. The notes sit forward, and strike a perfect balance between organic and textured, having a fair amount of body & weight with well-defined edges. Male vocals have an hint of that throaty feel. Female vocals sound delightfully emotional and euphonic. String instruments are sublime. The magic lies in how well each and every instrument are reproduced without overlapping each other, and even the faintest sound can be distinctly heard in the mix. Nothing dominates anything - it is a masterful cohabitation of all of them to their best capacity. What fascinates me most is that sometimes the instruments sound so alive that I feel I could just touch them.

Listening to Lana Del Rey has simply been a treat with them. Not just that, they also handled Bloodhunter quite nice!

Treble is smooth, yes, but very prominent. This region feels very present, and yet not pushed forward. They are placed slightly behind the midrange, but only in position, not in presence. The notes have a very realistic timbre - feel very tactile, and have very well defined body. The energy feels adequate. Details are easily noticeable. Upper treble extends very nicely and is quite airy.

The cymbals in Metallica - Enter Sandman, and Steely Dan - Do It Again sounded smooth but quite present.

Technicalities are fairly strong also. The stage is large with lots of space between the notes, owing to the open nature. It extends more in height than in width, although the width isn't bad either. Due to the forward midrange the presentation might sound a bit intimate, but the spacious presentation helps to keep it from being congested. Separation is outstanding, and imaging is quite fairly articulated as well.

Conclusion​

Rider 1 is just a glimpse of Kevin's tuning prowess. And it left me amazed since the get go. I honestly do not know what is not to like about this pair except perhaps a bit more rumble and body in the subbass, which I cannot really fault them with since it is not exactly a forte of any earbuds. The highly organic midrange, the punchy bass, and the smooth but prominent treble, coupled with an airy soundstage simply blows you away with a wave of pure musicality. Your only choice is to get on top of it and ride along! So godspeed!

Build
the yume 2 looks a stunner and is more on the compact side, thus being a very good match for people with small ears. it is a bit smaller than i'd wanted for my ears, but it was mitigated by the correct choice of tips. it seats deep and creates a perfect seal in my ears. needless to say there is no discomfort in my ears even after extended listening, and it quite literally vanishes in my ear (fit-wise). I do have concerns regarding the nature of the shells though, and it may turn out to be scratch prone but that is something I cannot verify. As other reviews have already mentioned, it is indeed a fingerprint magnet.



Sound quality
The sound of the yume 2 is balanced for the most part. It has a detailed and musical midrange and the overall tone of the sound is very pleasant. The midbass has tight and clean attack/decay but I wish it had more bass extension in the subbass region. Due to this, there is some detail lost in the lowest bass frequencies where there is rumble and deep attack. however for most music this might not be an issue. The upper midrange is very pleasant to the ears and even harsh female vocals come out as smooth and polished. The treble region for the most part is balanced and smooth but I wish it had more extension in the ultra highs that would have given it more air and micro details and spatial cues but that is me being nitpicky. the overall tuning is very good for the price



Conclusion
yume 2 is a definitive step up from the OG Yume but I still wish it had more extensions in both ends. but it is still an excellently tuned iem for the price.

Build quality
zetian wu heyday is a chunky iem but remarkably comfortable to my ears. it seats well and even after hours of listening there is no discomfort at any point. However, it may be too big for small ears. It is built like a tank and the materials and quality are substantial. The quality of accessories are really premium, specially the carry case, which is rare to see at this price point. I would have liked the cable more if it were thinner as it adds noticeable weight to the earphone when using.



Sound quality
The bass is tight and clean and very deep extension with a slight boost in midbass that is tastefully done. The resolution is excellent in all regions of the sound. The midrange is natural, dense enough and well centered with clean transparent clarity and great layering. The top end is very airy and extremely detailed and it offers a clean and neutral presentation that always keeps the sound engaging. the soundstage is wide and deep with laser sharp imaging. dynamics may not be the strong point of this iem and it may be overtaken with some dd iems in this market. Compared to the OG Zetian Wu, the Heyday version sounds more natural and has a better tuning overall. It is a more polished and better tuned iem than the OG Zetian Wu.



Conclusion
The Zetian Wu Heyday is a better tuned iem than OG Zetian Wu and it provides an amazing tuning aided with a highly technical performance which is unheard of in this price range.

Introduction:
ISN Audio is quite a renowned brand in the world of cables. I have had the pleasure of having the S4 cable in my possession, which provides incredible value in a very lightweight package. Recently they have released a new line with detachable plugs - C2 (copper), S2 (SPC), and H2 (Copper + SPC Hybrid). Penon Audio sent me a sample of the H2 for a review, so here I go...

Specification:
Brand: ISN Audio
Model: H2
Cable material: 6N+ OCC & silver-plated OCC hybrid
Cable Cores: 2 shares 72 cores, the wire core is 0.08
Accessory material: Aluminum alloy + carbon fiber accessory
Plug: 3-in-1 detachable gold-plated plug (3.5mm audio,2.5mm balanced ,4.4mm balanced)
Cable length: 1.2M

Disclaimer:
I was provided this item for free in exchange of my impressions. The impressions recorded below are solely mine own and as much unbiased as possible.

Packaging and Accessories:
The cable comes in a beautiful blue box with shiny ISN Audio logo and a cloth like cover on the shell. The box feels quite sturdy, although there is not much space inside. Inside the box there is the cable, the 3 connectors (2.5, 3.5, 4.5 mm), a cable tie with snap fit buttons, and a cable clip. The last two items are not in the photo below.



Build And Fit:
Now, the very first aspect of a cable that I look for is how pliable it is. I dislike stiff cables, and I dislike heavy and thick cables. So even if a cable is thin and light, if it is stiff, that is automatically a major con to me. One other aspect that I look for is how the build of the connectors, splitters, chin sliders, etc. - do they feel cheap, or do they feel well built and premium? Here again my first preference is always lightweight, as if these parts are heavy, they will create unnecessary pull on the cable and will give rise to discomfort.

And this is where it feels like ISN Audio really has considered all these aspects before making this cable. The cable is not thin at all, the individual strands are rather on the thicker side. However, since there are only 2 strands, the overall thickness of the cable is not very much, and even though it definitely is not as light as the S4, it still feels fairly light - I cannot feel any undue pull on my ears.
Just as well, the splitter, chin slider, and connectors are made primarily of metal, feel sturdy, but are not heavy at all. The matte finish black colour looks with slight carbon fibre decoration quite nice.



The detachable connectors are of 4 pin type, and fit quite snugly and tightly. Needs considerable force to detach them from the cable - which ensures no surprising detachment resulting in unexpected damages. There's a slot and white dot to properly guide the connectors. The plugs themselves feel pretty well made and fit in the respective jacks snugly.



Gears Used:
Hiby FC4 as the source, and I could not help but to pick the revered Penon Vortex to test the cable's performance - matches the colour scheme perfectly. Also, afterwards, I had a whim to try the one other blue iem I got, the MEAOES Eagle. The result was more than pleasant I must say.

Sound:
With Penon Vortex the hybrid characteristics of the cable is very distinctly evident from the very moment I played the first song. The low end has a very distinct emphasis, although not over the top, and feels full and slamming. The subbass reach is quite good, textures in the bass feel quite fleshed out and well defined. Midbass slams are tight and dynamic. From the stock cable the difference is really noticeable and multiple degrees more pleasing.

In the midrange, it feels as if the notes have grown slightly bigger and fuller, resulting in a more organic presentation. Textures are quite noticeable, but peaks are not accentuated. The midrange sounds slightly more open but not thin and peaky. Male vocals and string instruments seem to have more body with a decent grunt. Female vocals feel slightly more powerful and emotional. However, the overall transparency is in no way negatively affected by this - such is the overall improvement.

The treble region is made slightly more distinct without enhancing the peaks. This is really a wonderful effect the H2 has. The background cymbal rolls come into notice quite effortlessly, and yet the forward cymbal crashes never become piercing. Lower treble sounds very slightly more energised, while upper treble feels a bit more extended and the trailing edges are more prominent.

The overall presentation feel slightly bigger with a bit more expansion in height and depth of stage, a bit more dynamic and organic, and overall extremely pleasing. Despite the bigger notes there was no decrease in air or any hint of congestion. Separation was still the same wonderful as before.



With MEAOES Eagle, the result is very much in line with the Vortex. Eagle already has a decently powerful low end with a very slight roll off in the subbass, difficult to notice unless A/B-ing with other iems. H2 comes into play here and provides that last bit of boost in the subbass to make it fuller and bigger, but not boomy. Midbass notes similarly feel slightly bigger with more noticeable textures - which is a definite plus for Eagle.

As I already mentioned in my initial impression of Eagle, it has a very transparent midrange, albeit slightly lean. Well, H2 provides its magic touch here as well. The midrange notes become slightly fuller and bigger sounding with no loss of transparency. Male vocals and Guitars are the primary benefactors of this effect, as they become near euphoric after this. Female vocals were already quite magical in Eagle, but H2 elevates them to a slightly upper level as well.

As I already mentioned earlier, Eagle has a treble that was to die for. Seriously, I cannot emphasise enough how much I love it. It is brilliant, airy, sparkling, full of details, and never ever shouty or piercing. Well, H2 enhances this also! Imagine my surprise when with H2 I can suddenly feel the treble be more open and prominent sounding! No, it does not become overly bright or piercing, instead, the notes become slightly better defined with a wee bit more extension in the upper treble.

As a whole, H2 enhances and expands the already big sound of MEAOES Eagle. The overall presentation feels slightly bigger and bolder, with a bit more macro dynamics added. Stage was already massive, and that is not negatively affected, just the previously lean nature becomes fuller and more refined with the H2.



Conclusion:
ISN Audio H2 is a winner in my book, and it most certainly deserves its place among the default recommendations under $100. Grand sound - check, Soft and light - check, Sturdy build - check, Detachable connectors that fit tightly - check. I mean, it ticks so many checkboxes that it is very difficult to pick out any cons at all! The only con I could make out was with the carrying case, but even that was pushing it. H2 is a wonderful hybrid cable, and now it will be permanently attached to my Vortex.

Introduction:
Dunu Kima - an interesting name, a very welcome configuration, quite an extensive package, and a pretty lucrative price tag. No wonder it was winning hearts from the very moment it was introduced, and it certainly had my rapt attention. Kima in India means minced meat, just like in other places also as I understood from various facebook comments. I do not know the reason behind the name, nor the slogan Criz Faction, but those are just aesthetics and I am never much worried about them. A friend here, @gadgetgod, got the Kima for a review tour, and I willingly became a part of it for the chance to listen to it.

Packaging and Accessories:
I did not receive the whole package, just the orange carrying case inside which all the accessories and the IEM were packed. The carrying case is as always beautiful and I so very want to get one from Dunu, but cannot due to the already multiple cases that I have.



There are three different sets of eartips, but I only ever used the S&S one. The others seemed a bit too narrow bore, and considering the sound profile I was not inclined to use narrow bore tips.

The silver plated single crystal copper looked mesmerising to say the least. On top of that, it was soft and supple - one of the most important characteristics I look for in cables.



Build and Fit:
The Kima is built solid. The aluminium body is small, has a fair amount of weight, and feels quite sturdy. The matte finish is quite beautiful, although I cannot say I liked the geometric contours a lot - felt rather odd and incoherent.
Because of the small form factor, it fit inside my ears pretty snugly. Never could I feel the weight, nor did it ever popped off from my ears due to the weight.

Sound:
Kima is a very…safe sounding IEM in my opinion, but that isn’t necessarily a bad thing. Despite having a safe tuning, Dunu has managed to include enough elements of excitement to keep the listener entertained. The sound profile is very balanced, with perhaps the most emphasis given in the midrange. Tonality is neutral with a hint of warmth.



Bass of Kima is rather reserved in my opinion, which reflects in the graphs as well. The midbass notes have a controlled body, and an above average amount of weight. The midbass does not slam particularly hard, but does not feel weak either - somewhere in the middle it dwells. Textures are clearly produced though, both here and in the Subbass region. Even though the subbass notes do not have that physical presence or rumbling depth, they do not sound hollow. Sure, the notes could do with a bit more body, but the density of notes is just enough not to sound dissatisfactory. Decay is fairly fast so as not to clutter the stage.
When it comes to the bass drums of Bear McCreary-Battlestar Galactica Season 2 OST: Prelude To War, the fast subbass fails to portray the atmospheric reverberations they produce. However, in Deep Purple - Chasing Shadows and Eluveitie - Inis Mona, the bass guitar notes are very distinctly produced with quite a nice texture, and never do they feel lost beside the kickdrums. The double pedal of Metallica - The Four Horsemen is fairly distinctly present in the mix also, although could have done with a bit more meat.



Midrange is where Kima really shines. It really pops out from the whole spectrum - which truly produced a spark of pure joy the first time I noticed it. The hint of warmth really makes the overall tonality a pleasing one. The notes are really something here - they are very well defined, have just the right amount of body not to sound thin, the textures are effortlessly reproduced - overall they have a very distinct presence in the spectrum. The midrange sounds very nicely crunchy and have a fair amount of crispness, without giving rise to any kind of peaks. Lower mids do sport enough fullness that male vocals and string instruments start with a nice body, whereas upper mids have just enough energy coupled with a bit of smoothness to sound emotional but not uncomfortable. Thanks to the pronounced textures, the microdetails really stand out and amazes the listener.
The microdetails came into the highlight right from playing the Bear McCreary-Battlestar Galactica Season 2 OST: Prelude To War. The subtle details of the snare drum were pushed forward so beautifully, while maintaining an ample amount of body to sound natural and not thin - really caught me off guard. And since then I could identify this trait in every string instrument being played also. Male vocals like Leonard Cohen sounds really sweet, although the body at the lower register might not wow so much as the upper register. Female vocals are full of emotions, energetic, slightly on the smoother side and yet not sounding tonally off at the same time.



Treble of Kima has its ups and downs. The lower treble carried forward the good parts of the midrange - crisp, textured, energetic, nice body, right tonality, and distinct presence. The cymbal hits truly sound sublime in the mix. On the other hand, the energy in the upper treble is slightly toned down in order to, I presume, control the degree of brightness. It’s not rolled off, but it just does not command the same amount of body and the presence as the lower treble. The air seems slightly compromised as well hence. The trailing edges of the treble instruments do not pop out that well - which might or might not be a big deal, depending on the listener. Personally, I felt the trade-off can be accepted in favour of the whole complete package.
In RHCP - Dani California, the forward cymbal hits were very clearly produced and was hard not to notice, however, the background cymbal rolls were slightly subdued in comparison, but that did not detriment the complete presentation as a whole.



As I already focused multiple times, Kima is fairly competitive in the Technicalities section. The details, the bodies, the presence - nothing seems to have been compromised within the larger part of the spectrum. The separation between the notes are outstanding with clear distinction between them - nothing feels overshadowing the other. The presentation is rather intimate though - and that can be the only point of slight dissatisfaction, depending upon the listener. It’s not that the perception of depth is missing - it is very much there with a clean layering as well. The stage width is also respectable. It’s just that the height seems to be a bit less and the space between individual notes seems a bit less than what I would have expected - but really not a deal breaker, not at all. Imaging is not a bit fuzzy, may be not spreaded over a wide space, but not fuzzy at all.

Comparison:
Vs. Hiby Hela($89, Review Pending) - Right from the beginning, the very first difference that pops up is that Hela has a much deeper and more voluminous bass, albeit with slightly less resolution. That’s right, the very next aspect that struck me was that Kima had the upper hand in the individual note details and definition - the notes were slightly better constructed to give a slightly more real feel, and textures were slightly more pronounced. However, where Hela had the upper hand was treble extension, and, most importantly, the stage. Kima has a slightly more pushed forward midrange presentation, while Hela has its mids slightly pulled backward. However, that could not be the sole reason for the huge soundstage that Hela offered. There was another aspect - the notes of Hela felt to be very slightly leaner compared to Kima, but not anaemic in any way, and in fact I barely noticed it until I started A/B-ing them. So, anyway, the crux of the matter is that Hela had much more space between the notes, and hence had a perceivably bigger, airier, and more spacious presentation compared to Kima, which felt rather intimate. Both have their individual strengths and weaknesses, and I really cannot put one over the other.



Conclusion:
Just as I said in the caption, Kima is a Small, Simple, and Sweet offering from Dunu that I liked immensely. Point to be noted - liked, not loved. The reason being the Bass felt rather incomplete because of the slightly weak subbass depth and weight. The intimate stage is not a negative aspect in my opinion, especially given the outstanding separation and note definition it sports. However, I do prefer a rather meaty, and even not meaty, a rather complete lower end, and I felt Kima was missing it a bit. But nevertheless, it is what it is. And frankly, I was quite pleased at its upper end tuning, which I felt had more energy and air compared to Falcon Pro - which was rather reserved. Yeah, I like a bit bright treble as well, and hence I get biased when something does not have that. All in all, I can say that Dunu has pulled a pretty nice tuning with Kima, targetted for those seeking a comfortable, balanced, but not laid back presentation. Kima does all of them, and then some.

Introduction:
Penon has a pretty long history in the field of audiophilia, starting from their e-commerce website for audiophile products, going into the cable venture, and subsequently the IEM. The first IEM of Penon that I got my hands onto are the Orb, which I loved. The second was Fan, which was quite interesting and a very well done smooth sounding IEM as well - quite laid back and with a nice sense of space.
Since then, I fell in love with single DD iems, so the subsequent offerings from Penon, like Globe, Volt, Legend etc. did not entice me much. Serial was quite interesting as a triple DD IEM, but I had other competitive IEMs in that price range so never really got interested in it.
However, when the Vortex was announced, my curiosity got really perked up. A single DD at around $200, and it was rumoured to be entirely differently tuned than the previously signature smooth tuning. I somehow felt that I just HAD to listen to it, kind of a gut feeling per se.
So I reached out to Penon, and they happily agreed to provide me with a review sample! However, due to some unavoidable circumstances I was not able to deliver the review within the timeline they expected it. However, they graciously accepted my inability to do so, and I thank them for being so understanding.
That said, I also felt that I required the time I took to let the driver develop, or burn-in properly, to properly understand the tuning, and thereby I was able to properly analyse and put down my impressions.

Disclaimer: Penon provided this item to me free of charge for my honest impression. The impressions recorded below are solely mine and in no way affected by any outside influence.



Packaging and Accessories:
Penon follows a consistent style of packaging ever since Orb (with Fan being the only difference), and honestly I somehow like how simple and puritan it is. No flashy colours or design, very simple jacket and box, albeit appropriately sturdy. Inside, the accessories remain also the same irrespective of iems, (may be some minute add-ons in the recent models) - which proves the fact that the price difference solely reflects the actual difference in the sound tuning and drivers since there are next to nothing changes in the accessories.



The copper and SPC hybrid CS819 cable, despite being 8 core, is quite slim and soft. Very user friendly, and not bad sound-wise either.



There are a total of 3 types of eartips - Grey-Green, Transparent-Green, and ePro horn eartips. I played with the Grey-Green and Transparent Green eartips for a while, but eventually decided to settle on something else to suit my preference.
Cleaning brush and cable clips are standard. Never understood how to use the cable clip though.



The blue carrying box feels quite high quality, as always. There was also an added tiny faux leather pouch that I used for a while to carry the Vortex in my pocket - pretty handy I must say.



Build and Fit:
Penon Vortex is…tiny! Honestly, I was not expecting them to be so small! They just disappear inside the ears - the perfect pair to sleep on (not that I ever do it.) The form factor is quite compact without any unnecessary extra space, in fact, the 10mm DD occupies more than 85% of the shell cavity - and I love it! I forever wondered, regarding other iems, why the shell needs to be so unnecessarily large if the actual drivers are so small? Seemed like a waste of material, and by reducing them maybe a bit more raw material cost could have been saved. Well, with Vortex I had no such gripes!
The shell itself seems to be made of semi transparent blue plastic, which feels quite sturdy. The faceplate with blue and white swirls looks really beautiful.
The fit is rather shallow, though, so tips with long nozzles were required for me to get the best fit and isolation. One other thing to note here - Vortex has ZERO driver flex.

Sound:
So now, to the important part - How does the Vortex sound? Is it a vortex of notes? Swirls of emotions? What is it?
Well, I am gonna tell you what it is, but let me tell you before that, that this little piece blindsided me completely with its sound! I have had my run in with Penon’s iem, through Penon Orb and Fan. Orb was an extremely pleasing sound to say the least - smooth, warm, with a pleasingly full low-end and organic sound. Fan was not so much, but it still had its distinct merits. And then came this little guy, taking me completely by surprise!
Because Vortex is the complete opposite of the regular Penon house sound that I heard last or read about! For starters, it is one of the fastest dynamic drivers that I have ever heard. Despite being fast it still packs a punch. The tonality is generally on the bright side, which felt a bit overbearing in the beginning but settled down with time. The incredibly clean background it portrays is one of the first I have heard around $200, even more than Hiby Lasya that I reviewed some days before. Penon has truly hit it out of the park with the Vortex - such a brilliant and mature sound it has!



Low is where everything starts. And low is where Vortex surprises. From the initial listen my immediate impression was meh, the bass is lean. But somehow it still seemed fairly interesting, and as time went by and burn in progressed, I could clearly identify the strength the bass has. It is fast and tight, slams reasonably hard, disappears quick, but never sounds lean and weak.
The Subbass reaches quite deep, despite being not enough voluminous to qualify as juicy, but the body still feels appropriate enough. The magic here is in the textures. The subbass textures here are reproduced quite prominently, which, combined with notes with sufficient weight and body gives way to a very detailed subbass. There is a certain bite to the notes that captures the one’s attention easily.
Then comes the midbass, and along comes another surprise. Despite the polite tuning, the midbass slams reasonably hard. There is no sense of restrain here. Granted, the body of the notes are not entirely up to my satisfaction, however, they do not feel incomplete or half-hearted either. Hits reasonably hard, decay fast, does not clutter the stage - to my ears, they sound unique and successful at what they were trying to do. Yes, I am well aware of the bass mod that is being actively explored in the Penon thread; I, however, felt that doing that will rob it off its signature that Penon was trying to achieve, and I should respect it.
The underlying rumbling bassline in Deep Purple - Chasing Shadows and Eluveitie - Inis Mona sound quite pronounced and distinct even beside the drums. The hard slamming drums in Red Hot Chili Peppers - Dani California and the fast but slightly soft kickdrums in Metallica - The Four Horsemen declare their presence quite prominently and never sound weak. However, the thunderous bass drums in Bear McCreary-Battlestar Galactica Season 2 OST: Prelude To War do not exactly reach their full thundering glory, but still, sound quite full. In Hans Zimmer - Why So Serious, the subbass sure reaches low, but due to the lack of volume cannot exert as much pressure as it should to become atmospheric.



Midrange of Vortex is a clean and quite magical affair. It might not give an orgasmic fullness, but it will give you a clean, crisp, and quite transparent presentation while not skimping out on the body of the notes…it caught me off guard from the very first listen! String instruments are an absolute treat to listen to on Vortex. Crunchy? Check. Well-bodied? Check. Detailed? Check. Dynamic? Check. Peaks not exaggerated? Check. For example, I am listening to Tina Guo - Cello Metal album, and I cannot stop grooving along with the tracks! The electric guitars sound quite crunchy and the textures are to die for. And then Tina Guo’s marvellous Cello comes into action, goodness! In one track the dynamic rawness and the gritty texture just pops out and takes one’s breath away! The next track the cello is strong but melodious, taking the centre stage, transitioning between a fast noisy nature and slow musical nature - Vortex accurately portrays that along with all the minuscule variations, bringing out the finer micro-details in the textures effortlessly. And hereby Vortex pulls off another great feat - by bringing the finest details of the background instruments to immediate notice. No, Vortex does not push them forward, but despite how busy the tracks are, the microdetails of the instruments background pops out quite well.

Despite the crisp trait, male vocals still sound adequately organic and natural. They preserve enough of the weight that adds the pleasing throatiness, while avoiding any unnecessarily thickening of the notes. What’s more astounding is that the notes do not lose any of the textures in the process - there is no smoothening, and neither is there any over-accentuation of the peaks. Even in the rough vocals, like Metallica - The Four Horsemen, Enter Sandman, Eluveitie - Inis Mona, or strong vocals with peaks, like RHCP - Dani California, it never gets uncomfortable. Rather, they pop out quite nicely even from inside the busy mix they are in. Leonard Cohen and Mike Saaresto have a nice deep voice with evident sibilance. Vortex does a wonderful job in bringing out the weight, while hinting at the sibilant parts but keeping them under a tight control. In my opinion, the way Vortex makes the vocals stand out, however recessed it is (Metallica - The Four Horsemen, Tool - Stinkfist), is truly impressive.

Let us focus on the female vocals, which get a largely similar treatment like that of male vocals. They are brilliant, silky, textured, full of details, occasionally hinting at the inherent sibilance but never going overboard, just right tonality - yeah, I cannot find anything dissatisfactory in them. Even the body seemed quite appropriate - never felt unnaturally thin, never felt unnaturally thick. They have a distinct presence with the original nature intact. Sara Bareilles’s slightly raspy voice in Love Song sounds alive and kicking - yes, the roughness is present, not smoothened, peaks can be clearly apprehended, but never becomes uncomfortable. Same goes for Yao Si Ting in Scarborough Fair, her voice here is silky, but has occasional sibilant peaks - Vortex reproduces those peaks in their original nature, neither smoothens them down to comfortable level, nor accentuates them to make me wince. To be more precise, Vortex presents the female vocals in the way they are intended to sound - the transparency helps to enhance the overall experience even more.



The High frequency region does not disappoint either, in fact, they are equally impressive. It’s not easy to find an IEM that manages to reproduce all of the frequencies in an equally satisfactory manner, but somehow, Vortex does. The whole high frequency region has quite a fair amount of brightness, and there is not a bit of early roll-off. The lower treble sounds quite energetic, neutral in tonality, and very very well-textured. What’s even more pleasing is that the upper treble has an equally pleasing amount of energy, enhancing the air with all those fine micro-details. Not a hint of smoothened edges, but no uncomfortably accentuated peaks either. The brilliant cymbal crashes, the sparkling cymbal rolls, the fine textures popping out from the decays - coupled they create one of the most pleasant treble representations. I can confidently say these are some Sweet, sweet Treble. Metallica - Enter Sandman, The Four Horsemen, Steely Dan - Do It Again, RHCP - Dani California, Tool - Stinkfist, Neil Young - Misfits…all of them have varying degrees of brilliant treble showcases, complete with cymbal crash, roll, hi-hat, sticks, cowbells, etc. Vortex brings out the best of them with distinct notes, vibrant tonality, and superfine micro-details.



In the Technicalities section, as already multiple times mentioned, Vortex pulls quite ahead of the other competitions in terms of the brilliant textures and fine details. The notes do portray a very nice sense of realism. It has a very nicely clean background as well, along with a high degree of transparency. And if it is not evident already, the whole presentation is highly dynamic and engaging.
Now, coming to the soundstage, interestingly it seems that Penon has gone for a somewhat intimate stage. The forward midrange might be a reason for that. The width of the stage is quite commendable though, extends well outside the head on both sides. Depth I would say is above average - it does not extend very deep, but it most certainly is not flat. Height is one aspect that Vortex’s soundstage lacks, and frankly this might be the only chink in the otherwise solid performance of it.
However, one aspect has to be highlighted here - despite the intimate stage, the presentation never felt boring because of the impressive imaging it has. The front-to-back layering is quite excellently done. Each instrument is placed quite distinctly inside the stage and while it might not be completely three-dimensional, it still gives me much satisfaction.

With an Upgrade Cable: Now, I felt compelled to include this special section as I genuinely felt that Vortex had more to give. Make no mistake, the CS819 cable provided by Penon is a pretty good hybrid cable in its own merits. However, the incredible tuning of Vortex sparked a curiosity in my mind that what would happen if I pair it with a different, and more importantly, pure copper cable.
Hence, I swapped an Empire Ears Alpha-IV cable on it…and voila! I could detect an immediate improvement in the stage depth. The midrange also got pushed back slightly which attenuated the intimacy ever so slightly. I could also perceive a tiny bit more space between the notes. All these improvements gave way to slightly more enhanced imaging as well. No considerable improvement could be detected in the textures and definitions, although they did not need any to start with. The treble got accentuated very slightly, and a tiny amount of weight felt added to the bass slam and subbass rumble - which made it even more pleasant.

I threw another pure copper cable, EarAudio Anasa, 8 core 28 AWG 4N Monocrystalline Copper, on Vortex. The difference with Alpha-IV was imminent. With Alpha-IV the midrange was a bit more hard hitting with slightly bigger note, subbass rumbles had slightly more body, and stage was also slightly more intimate. With Anasa, the midrange notes became very slightly smaller with slightly softer attack (which in no way had any detrimental effect over the complete soundsignature), subbass rumbles body felt very very slightly lean, and the stage opens up a bit with increased depth. Overall, I liked the final effect it had on the sound.

And with this, I can say this with confidence, that simply a cable upgrade has made the Vortex earn a complete from me!

Effect of Tips: Now, this is another section I have not ever considered to include, but somehow, given how moody the Vortex is depending upon tips, I felt compelled to mention it separately. Here goes:

Azla Sednaearfit - Soundstage becomes larger, at the cost of bass slam.

Stock Grey/Green - Nothing satisfactory, neither bass slams, nor stage expands.

Stock White/Green - Better bass slams, but still nothing special.

Final Type-E White/Pink - Best bass slams, but stage becomes more intimate and space between notes reduces.

Generic Red core Grey umbrella - Long nozzle, hence nice stage, but despite the narrower bore from stock White/Green, bass slam is not much improved due to soft umbrella.

Tanchjim Bass (from Ola) - This provided me a lot of satisfaction in terms of very nice bass slams and very nice stage. But the bores were too pliable, and came out of the nozzle once on its own in normal handling itself. Changed it promptly.

FAudio Instrument - This is my current pairing. Provides a beautiful balance between bass slams and stage.

It was quite difficult to get a perfect seal because of the slightly shallower fit, hence it took me quite awhile to land the best pairing.

Comparison:
Vs. Hiby Lasya ($199): I very recently reviewed the Hiby Lasya, which is an outstanding IEM in its own merits. As the Penon Vortex is also around the same price point, I felt it would be justified to make a comparison of them.
The first difference that sticks out immediately is the tonality. Lasya follows a largely smooth and laid back approach with just enough dynamics and a distinct touch of warmth so as not to make the overall sound dull. Vortex, on the other hand, has a largely technical approach to the sound, which is also quite dynamic, and has a rather bright tonality with a very slight hint of warmth.
Regarding Bass, Lasya has a tiny bit more quantity. The subbass rumbles have definitely more body and feels distinctly more atmospheric. The midbass slams, on the other hand, despite having a bit more body, feels slightly softer in comparison. Vortex pulls ahead in sheer quality of the bass. The whole low end region is more tight and snappy in comparison. The textures feel notably more pronounced and detailed. Midbass slams a bit harder. Both of the mhave their own strengths here.
In the Midrange, Lasya is a bit more smooth and feels a touch more organic. The notes have a tiny bit more body in the comparison, but not a lot more. In line with the bass, Vortex mids are noticeably more textured and details feel more pronounced. The notes of Vortex also feels to have more bite.
Treble region is where Lasya plays a bit more safe than Vortex. No, it is not muted, but it is not super energetic either. The extension in the upper treble is above average whereas the lower treble has a fair amount of energy. Vortex has a notably more energetic treble region, with more brilliance in the lower treble and more sparkles in the upper treble, the extension is better as well, as are the textures.
Soundstage is where lasya excels notably over Vortex, owing to its much better height and depth. Lasya has a distinctly more expansive stage over Vortex.Vortex, however, seems to perform slightly better in terms of imaging - the positioning of instruments feels more distinct. Layering seems to be about similar in both.

Conclusion:
Fast, Precise, Incredibly Well Textured, Vibrant, Clean, Transparent, Dynamic - these are all the words that are associated with Penon Vortex in my mind. It is an incredibly solid performer in a surprisingly small package. The fine microdetails, prominent textures, transparent and dynamic sound, intimate stage coupled with pinpoint imaging - all of them envelop you from all sides, slowly drawing you nearer and nearer to the centre of the music. The more time you spend with them, the more enamoured you become. Quite frankly, I was not expecting such a mind-blowing performance from such a small and compact IEM…but it really proved how an incredible driver tuning works the magic! This is now my default recommendation for anyone who wishes to get a sound as described in the very first line of this section. Penon Vortex is truly a maelstrom of small ingenuities that might not sound much impressive from the get go, I remember I found them a bit bright and thin sounding with a rather lacklustre low-end in the beginning, but the more time I spent, the more trapped I got in its flow, and now I can say this is one entrapment I am not looking to get out of anytime soon.

Introduction:
Hiby has been a long term player in the sources field, and recently has entered into the IEM market as well. In general, Hiby’s DAPs are held in high regard, and having listened to RS6, I hold the same opinion too.

Hiby started their foray into the IEM segment with Crystal 6, a 6 BA iem. Now, I was not much fond of BA bass (still am not), hence I never really paid them much attention. However, this year, a few months back, Hiby announced the Lasya. Now, that immediately caught my attention. Why? Because Lasya is a word of Indian Origin, and being an Indian myself, I was instantly interested! I reached out to Hiby, to understand why they decided on this particular name, and whether the essence of the Sanskrit word Lasya was taken into consideration.

Hiby replied this:
The term Lāsya in the context of Hindu mythology describes the dance performed by Goddess Parvati as it expresses happiness and is filled with grace and beauty. The Lasya was designed with recreating the emotions and soulfulness of a female performer in mind, and the faceplates are as colourful and beautiful as the dancing goddess. So we felt that the name Lasya goes well with our product image and our slogan for this new product is "born to sing". That's why it is named "Lasya".

Well, suffice to say I was quite pleasantly surprised by the thought they had put behind it and of course quite glad at this cultural appreciation. I asked Hiby whether I may have a chance of reviewing them, and they obliged and sent me a review sample. So here are my impressions below.

Disclaimer:
I received this item from Hiby for free in exchange for my honest opinion on this. I have recorded my impressions below while trying to remain bias-free as much as possible.

Packaging and Accessories:
When I received the box, I was surprised at how refreshing it looked from the outside. The near-perfect cubic shape, the flowing silver letters, and the subtle design in the background - had a very bright Autumn vibe to my eyes.

Under the cuboid top cover lies the first layer housing the earpieces lie. Beneath that is the layer where the 3 types of silicone eartips are housed - Crisp, bass, and Balanced, along with a pair of Memory Foam eartips. I used the Crisp eartips for a while but eventually settled with the BGVP W01 eartips which made it sound its best.



Pick up that layer, and underneath is the Big case. Yes, it is Big, and Round with a bulge and padding on the inside for extra protection - exceeding my expectations. Well, the volume was needed to house not one but TWO Cables.



Yes, Lasya is perhaps the first iem that I came across at this price range (under $200) that comes with two cables - one 4.4 mm balanced and another 3.5 mm single end. A pleasant surprise, to say the least. However, and I do not know why, Hiby has decided to go with Pentaconn Ear connectors instead of the more conventional mmcx or 2pin. Acoustune is the company that introduced these connectors first in their product line, I think. But I do believe that going with this connector might have prompted Hiby to include the balanced cable, as a lot of us are preferring to use balanced over single end, and Pentaconn Ear balanced cables are not exactly easy to come by. Props to Hiby for that.



Build and Fit:
Lasya is completely made of a semi-transparent acrylic shell which I believe is also filled with Acrylic. The shell, albeit light, feels quite sturdy. The Hiby has employed a unique design of air pathway, as shown below:



In Hiby’s words: The convective intake and exhaust acoustic chamber design is fully integrated with the housing, effectively eliminating pressure differential and driver flex. It achieves the beautiful wear design of CIEM styles while obtaining the same acoustic utility as traditional utilitarian driver housings. Eliminating pressure differential and driver flex makes for freedom from channel imbalance upon tight fit and a clear sound and a soundfield that extends out of the head.

Basically, it seems that the front vent is ported towards the back of the housing. Something unique, no doubt, but not exactly groundbreaking. How accurate the claim of 'soundfield that extends out of the head' is, we will see later. However, I can confirm that the semi-custom shape of the shell is in fact extremely comfortable and fits like a glove inside the ear. Also, there is absolutely zero driver flex. The green shell looks appropriately luscious for the name with the beautiful faceplate and the gold lettering.

I have tried to capture the ports in my photos. Here are some close-up looks:





The OCC cables are quite slim, but not thin, and quite supple - which is a plus for me. The SS parts feel sturdy. Overall, they do feel like quality products.

Sound:
Before speaking about the sound, I must speak about the store produced frequency response graph, or rather, how inaccurate that is. Take a look below:


It is quite obvious from the above that there is a very strong bass emphasis of almost 10 dB over 800 Hz that continues almost horizontally from 20 Hz to 250 Hz. This most definitely signifies a full blown bass. And yet, when I received it and put it in my ears, I was pleasantly surprised with a much much more controlled bass, which I was totally not expecting!

Then, techpowerup published their review of Hiby Lasya, along with a measured graph. Take a look at the below link:
https://vsg.squig.link/?share=VSG_Target,HiBy_Lasya

In quite the stark contrast to the store produced graph, it shows a very gentle rise from 500 Hz of about 7 dB at most till 20 Hz. Now, this explains the actual bass response that I was hearing perfectly, and I was content.



With this out of the way, let us plunge into a more thorough discussion on how it sounds:

The tuning of Lasya felt so matured from the very first listening, that I was totally captivated. It felt smooth, and yet not muted. The transparency was quite decent, quite clean midrange. A gentle boost in the bass, and a boost in the mid treble region to add a bit of sparkle, do the magic. The overall sound is quite comfortable for extended listening, and yet you’ll never feel that the sound lacks life. Due to the gentle boost in bass and treble region, coupled with a balanced mid range (not too far back, not too forward either), the overall presentation becomes really engaging. The tonality is a bit on the warmer side, which adds to the listening comfort. It is quite clear that Hiby has gone in the opposite direction of trying to push out as much detail as possible. What Hiby has evidently tried to achieve is creating a sound that is comfortable to listen to, has enough air to not feel congested, and is dynamic enough to make it engaging. Of course, compromises are made here and there, but the whole feels greater than the sum.



Not even once the low end feels overwhelming, and yet it never feels missing either. The gentle boost makes the bass stay at such a level where it makes its presence known and felt distinctly, but never fights to grab your attention. One might think that to attain such balance the bass had to compromise a full bodied presence. Well, in that case they’ll be in for a surprise! The mid bass slams, albeit gentle, never felt half-hearted or lacking body. They have quite a full bodied reproduction. The notes have a very nice weight that adds a touch of physicality without emphasising them. The double pedal kickdrum slams in Metallica - The Four Horseman, the timbale and drums in Deep Purple - Chasing Shadows, the attacking drum beats in Red Hot Chili Peppers - Dani California sound appropriately impactful, weighty, and present, without eating at the stage. However, it’s not just the midbass that is masterfully tuned, subbass gets the same treatment also. If splitting hairs, subbass might seem to have a tiny bit of more emphasis than the midbass. The bass guitar rumbles in Deep Purple - Chasing Shadows, the individual plucks of bass guitar strings in Leonard Cohen - Hallelujah sound wonderfully deep and well-bodied, and very slightly more present over the drums. Textures are not bad, in spite of having a bit of smoothness - which gives the impression of masking some details, but frankly, in my whole listening session I never once felt it was lacking anything.
The checking of low end always ends with Bear McCreary-Battlestar Galactica Season 2 OST: Prelude To War. The thunderous bass drums here sound a bit controlled, although they definitely do not sound hollow. Sufficient weight was present throughout the track. While they do not slam and rumble in their full glory, they certainly do not sound lacking body or weak. On the other hand, the double bass set up a very nice groundwork that grows from being in the background to commanding a frontal presence along with the drum, and all throughout this transition they sound consistently deep and full bodied without becoming overwhelming.



The single defining trait of the midrange is how incredibly organic it sounds, while still boasting a decent amount of transparency. The notes have a beautiful combination of the right amount of body, crispness, and slight smoothening of edges; together they provide the midrange a beautiful lushness that I simply could not get enough of. Instruments like stick hits, snare drums, sound crisp enough to stand out, but the smooth edges blunts the attacks a bit - which was not a deal breaker for me. The same applies for guitars, although, in this case, the acoustic guitars attain a more natural timbre. The note weight sounds quite balanced, neither too lean nor too thick, and the attack sounds appropriate. Estas Tonne and Antoine Dufour - I love these two acoustic guitarists, and both of them sound absolutely magical on their respective tracks - Strings Of A Bard and Development. The guitar notes sound really crunchy and alive. Coming to electric guitar, Joe Satriani sounds mesmerising in Always With Me, Always With You, however, a bit more energy here would have been more appreciated. The rhythm guitars in Evanescence - Imaginary sound quite crunchy, textured, and maintain a distinct presence in the mix. The snare drum rolls in Bear McCreary-Battlestar Galactica Season 2 OST: Prelude To War sound a bit dull and not as textured as crispier and livelier sets, but not totally washed out and blunt either - have enough crispness to still sound satisfactory.
Male vocals are given a somewhat neutral treatment here, but that does not imply they sound dry. There is a distinct warmth here, with the notes having satisfactory weight and body to sound natural, but not thick enough to sound juicy and heavily coloured. They do still sound organic enough that I never once had to grimace in dissatisfaction. Lasya reproduces the textures in the vocal quite well, but smoothens the rough edges to minimise discomfort - and that is truly a masterful tuning, again. The deep baritone parts of Leonard Cohen in Hallelujah sound appropriately deep and full bodied, while Marko Saaresto’s ‘bass-baritone’ voice has the right emotional touch in The Ballad of Jeremiah Peacekeeper without sounding grating or harsh. In both of these cases, the sibilant sounds (s, z, sh, zh) are smoothened out not to cause even the slightest discomfort while still reproducing them clearly. When it comes to rasp and rough or gritty vocals, like Eluveitie - Inis Mona and Metallica - Enter Sandman, Lasya portrays them in such a manner where the rough edges do not get overly emphasised, and yet the overall gritty texture is reproduced well along with a fullness that helps the vocals attain an appropriate presence and avoid thinness.
Now, let us talk about the female vocals, which, as claimed by Hiby, Lasya is tuned for. And Lasya delivers here. The way the female vocals get portrayed here is this - the energy of the female vocal is preserved in ample quantity, slight hint of warmth is added to enhance the emotive factor, and in line with their main tuning philosophy the sibilant notes are smoothened a bit for listening comfort. What it culminates into is a beautiful and sweet sounding female vocal that never goes out of bound despite how sibilant it gets, and yet never fails to deliver the underlying energy. Celine Dion’s soaring voice in The Power of Love, Christina Aguilera’s powerful voice in Hurt, Yao Si Ting’s silky voice in Scarborough Fair, Cherryl Wheeler’s jolly voice in I Know This Town, Amy Lee’s versatile voice in Going Under, My Immortal, Hello, Sara Bareilles’s slightly raspy voice in Love Song - Lasya brings out the most of them every time without sounding strident. And this is what I believe is one of the greatest feats of Lasya and how it justifies Hiby’s claim regarding its tuning. Other iems in a similar price range that I have listened to, none of them have ever managed to play all of the above vocals equally beautifully. Some of the vocals would sound ethereal, and then some would sound too sharp and peaky. Lasya is an enigma here where it made all of them sound great without giving any special treatment.



Treble section of Lasya sounds a bit controlled, but thankfully not muted and super rolled off. I’d say they are more on the comfortable side without severely compromising the energy. In fact, there is quite a noticeable amount of energy at the lower trebe region, while the upper treble region is a bit pulled back. Although not as bright and sparkling as other bright sounding iems like Penon Vortex or Azla Horizon, the treble of Lasya still stands out quite well to make its presence known without getting in your face. Somehow, Hiby managed to tune the treble such that the energy is quite sufficient to make it engaging, and yet had the rough edges smoothened to preserve the listening comfort. The notes have a slight warm tonality while having just enough body. Point to note - despite the smoothed edges, the treble notes still sound crispy. I’d like to say, while this kind of treble is certainly not for trebleheads, they are still of just the right quantity and quality to make the whole tuning achieve the balance it was aiming for.
In Katja Maria Werker - Contact Myself the background treble notes are nicely reproduced and have a distinct crispness. Not very bright, yet not subdued. Same goes for Metallica - Enter Sandman, the forerunning hi-hat roll sounds pronounced yet never peaky. Cymbal crashes are quite easily discernible in the mix as well, although not as bright and sparkling as other sets I mentioned.



Talking about the Technicalities, I would say the Lasya is fairly technical. Not too much due to the slightly smoother notes, not too smooth to sound mushy. Again, there is a nice sense of balance. Crisp notes with smoothed edges isn’t something I come across regularly, and hence, when I have, I have tried to make sure to point that out.
Although, that’s not the first attribute that comes to my mind when talking about technicalities.
Rather, what first comes to mind is the outstandingly open presentation it creates. While the stage width and depth are quite above average, the excellent height it has elevates the whole presentation to quite a grand level. The imaging is one of the best I have heard in this price range, and the air between the notes is plenty. Separation is quite nice again. Everything together, it certainly makes an attempt to get close to a 3-dimensional stage, and achieves about 80% of it, in my humble opinion. This wide open presentation is certainly one of the best aspects of Lasya, as I surely wasn’t expecting this given that its tuning was on the smoother side. And here, the statement, 'soundfield that extends out of the head' gets justified.

Conclusion:
Hiby Lasya is an enigma. It is smooth iem done right. Those who know me know that I love my treble as I love my bass, powerful/energetic, tight/sparkling, and with a nice controlled decay. Lasya by no means has sparkling treble, and yet I simply cannot think the treble is anything less than satisfactory. I think this has more to do with the sum of the individual attributes that it has. The low end is not the most full-bodied, nor does it slam exceptionally hard; it is tight though. The treble is not highly extended, although has an above average amount of energy at the lower treble and sounds crisp. The midrange is surely magical, such is the open and airy presentation. And when all of them come together, the listener, I in this case, can’t help just float in the music while having absolutely zero concerns towards finer details. Lasya was truly “born to sing”, emotionally and soulfully. I find no fault in Hiby’s logic behind the naming. Lasya focuses on musicality and brings out the happiness in the music rather than focusing on extreme technicalities. I mentioned ‘extreme’ because Lasya is indeed fairly technical. Hiby has pulled off a wondrous tuning and I will surely be looking out for the further single DD offerings from them. For the time being, Lasya is my go-to iem whenever I need to take a change from sheer technical sound or when I just need to relax.

Introduction:
Azla has gained a fair reputation in the field of eartips. Sednaearfit, Sednaearfit Light, Sednaearfit Short, Sednaearfit Light Short, Xelastec, Crystal - all of them are pretty highly appreciated in the audiophile community. I personally have the Sednaearfit Light and Light short, along with the Crystal, and I love them. I very much want to get my hands on their Sednaearfit Vivid edition as well, but cannot find a suitable vendor who will ship to India, and they are not yet available with local vendors also.

While researching Azla, I came to find out that they have some iems as well. I gave them a cursory glance in the past and thought nothing much about them. However, after that my preference changed, and I got completely inclined to single-DD iems. I have kind of a treasure hunter syndrome (coined by myself), I always try to look for those gears (mostly iems) which have stayed out of the limelight, but which might have solid potential. If you’d look at my signature you’d know that. Anyway, that is how my search for a TOTL iem landed me on FAudio Dark Sky. I located it on zeppelinandco, and shot them a message asking for a review sample for a discount. They agreed, and just then, by luck, the Horizon on their site caught my glance. This time, I put some more time into it, looking deep into the tech, combing through the handful of reviews it has online, and decided to play a gamble on it. Asked zeppelin for a similar reviewer’s discount, and they agreed. And that is how I came into possession of it.



Specifications:

• Driver Unit: 8mm new SF ARD(Advanced Research Driver)
• Sensitivity: 103dB
• Total Harmonic Distortion: Less than 0.5%
• Rated Input: 5mW
• Max Input: 20mW
• Impedance: 27Ω ±10%
• Frequency Range: 5Hz - 30kHz
• Weight: 24g (with cable)
• Plug: 3.5mm stereo

Disclaimer:
I bought this from Zeppelin&Co. for a reviewer’s discount in the promise of my honest opinion. I have recorded my impressions below while trying to remain as much as bias-free.

Packaging and Accessories:
Azla has gone with quite the minimalistic approach with the packaging of Horizon. A plain black cardboard box with black sleeve. Although the inscription of the titles feel fairly premium. Inside is a compartment with cavities for the earpieces and the cable. Below that is 2 flat boxes containing eartips. There is some literature in a black envelope as well, but I did not spend much time with it. There was no carrying case or carrying pouch.








The cable that came with Horizon seems to be nothing special, although not particularly cheap. The sleeve seems to be a rubbery kind of material with a pretty high coefficient of friction, and hence very prone to getting tangled. The details of the cable is as below:

Cable For Superior Sound
AZLA fully understands that cable is extremely important. Therefore, researched and developed the best cable through long time, and finally succeeded to apply the result to Horizon.
Urethane-coated high-quality copper wires are built with 128 strands total (32 copper wire, Kevlar/250D*4 cores), present accurate sound with low impedance through various treatments.
Also, applied superior cable weaving method, which is used for high-end earphones only, and finished 4wires cable weaving for L/R, after that, able to experience the quality sound.

Click to expand...

Well, from the description it seems to be of fairly good quality, although I am not sure what sonic properties the Kevlar/250D*4 cores provide, or whether it’s just there for structural reinforcement.



The eartips were regular run of the mill short stem wide bore tips. I didn't understand the idea of including the same type of eartips twice. As a saving grace the earpieces came with Sednaearfit M tips attached, but even though I was disappointed, as I found in a previous review that it came with one full set of regular tips and one full set of Sednaearfit tips. I contacted Zeppelin regarding this, and upon checking they confirmed that this is how they received this product. Might be a reshuffling of the packaging. Anyway not a severe deal breaker per se.







The absence of a carrying case or carrying pouch was really something that I disapprove of. At this price range, a carrying case is a given, especially when iems 1/10th of its price are coming with at least a soft carrying pouch.

Build and Fit:
The build of Horizon is quite unique. The actual functioning part is a single metal cylinder that houses the dynamic driver and extends from the back to the front of the earpiece. The middle portion of the cylinder is housed within a polycarbonate (yes, polycarbonate, just regular polycarbonate) shell, which, from the first glance seems to have a lot of empty space save for the pair of cables, but it actually has a different purpose, which will be detailed below.



The nozzle is quite long and reaches deep within the ear. It also is on a somewhat wider side in respect of diameter, about 5 mm wide. Both of these coupled together makes it a tricky fit. Any eartips that I put it on, had either of the two problems: First, it was either slightly narrower than ideal, which, despite the deep fit, did not provide the correct seal; or Second, the eartips provided a snug fit and strong isolation, but also put pressure in such a way that had some effect on the sound signature. It did not become painful or anything, but I could detect that if my ear moves (yeah I can wiggle my ears), the pressure on the inside of my ear canal lessens slightly, and the sound seems to open up slightly more, without breaking the isolation. Despite the strong isolation, I would like to mention that there was absolutely zero driver flex. Also, once I could achieve an ideal seal, I largely forgot that it was even there.



I am not a fan of the PVC shell. While it makes it quite light in weight, the shells themselves are not very hard and hence quite prone to scratches. I am using it as an everyday carry, and while I always keep them inside a cloth pouch, there are several fine scratches on them already. Although I never have any concern regarding the durability of it, it seems to be pretty sturdily assembled.



Tech Inside:
Normally this is not a section I include in my other reviews, however, Horizon is special. It employs some such unique techs inside that I felt obligated to talk about them. I won’t go into rewriting them in my own words to avoid unnecessary hassle, I am just copy-pasting them from their website:

Infinity Advanced Research Driver
SF(Superior Fidelity) Driver: Developed by Professor Shin-Ryeol Lee, the next generation’s driver which removes partial vibration at the driver, enables it to play original sound.
Upgraded SF driver, which is the main part of INFINITY ARD, produced stronger diaphragm by ‘46nanos 3 multi-layers' method, providing minimum partial vibration with shape of diaphragm through scientific 3D scanned analysis.

Click to expand...

Characteristics of Sound
The special thing is, fundamentally closed phase distortion due to whole sounds are made from one diaphragm without crossover network. Throughout scientific diaphragm analysis, there is able to minimise partial vibration, therefore it is able to play super high frequency range which is over 30kHz area, and minimised phase distortion and frequency characteristics through the sole diaphragm, which it was unable to reduce with common earphone structure. Especially, by adding ‘Air Flow’ technology, which is a system of Infinity Driver for AZLA, minimises sound distortion and improves staging, space impression and sense of hitting. In summary, the main advantage is to be able to realise the natural acoustic atmosphere and sense of hitting though bass range.

Sound Air Vent Holes
HORIZON is engraft Air Flow technology which is used for AZLA-01R, improves space impression and staging sense. For clearer and deeper sound, applied two holes with Air Flow technology to the metal housing, it finishes INFINITY ARD and provides a very special hitting sense, deep and rich bass and specialised wide staging. Through Horizon, able to enjoy natural sound and concrete low sound,
never experienced before with conventional earphones.

Drawing For Best Sound Quality
Horizon’s design has been started to make earphones as a speaker. For ‘space’, like a loudspeaker, AZLA researched hard and finally found the best design to apply to the production. Material also, after numerous trials and errors, the top grade of polycarbonate housing is chosen and combined with metal housing.
Assembly method of AZLA Horizon is a patent pending method, it is completely new. Regarding assembling different materials, applied ‘sound prefer’ method. Minimised chemical assembly way (bonding), and best sound is provided through screw-finished way, of course whole parts are fixed well. Horizon is applied the best shape for the best fitting at human ears throughout many modelling and tests, after that the user is able to enjoy the best sound with the best and stable fit.

Click to expand...

Well, as explained in the Sound Air Vent Holes section, along with the above line diagram, it is clear that within the polycarbonate housing the metal cylinder has small vents, through which air circulation occurs between the metal cylinder and polycarbonate housing. This, along with the two air vents on the conical portion in the back, might help create such an immersive stage combined with a deep and hard hitting bass. Well, this is purely my guess, because no words regarding that internal airflow is mentioned anywhere in the official product page.

Sound:
It’s not every day that I fall in love with a iem that has a very crowd pleasing V shaped tuning. I love a bit more balanced sound. Nice bass slam that stays controlled, clean and slightly forward midrange, sparkly highs…more like a W shaped sound. However, Horizon is quite an excursion from that. It has a typical V shaped sound that can be found in some quite popular iems, namely, Ikko OH10, Sennheiser IE300, Kinera Norn. And if anyone has read my reviews, they would know that none of them did particularly catch my fancy.

Well, Azla Horizon changed that.

When I first put them in my ears and started playing, there were three aspects that immediately caught my attention:

1. The Big and Bold Bass
2. The quite energetic and somewhat sharp highs
3. The sense of a well crafted three dimensional space

In that order. While the first one was a guilty pleasure and the third one was a genuine pleasure, the second one was a concern. The Azla Sednaearfit M tips were still on, they came pre-attached. And while they did enhance the three dimensional stage, they also enhanced the energy in the upper mid and highs. Which, from the below frequency response curve (taken from crinacle’s database), is already in abundance.

So, I did a lot of tip rolling, and finally settled on the generic red bore dark grey flange eartips, which are available on Penon and come bundled with a lot of iems. The bass was enhanced slightly more, the stage got slightly smaller (but still providing plenty of satisfaction), and the energy in the upper registers felt dimmed very little bit - which was welcoming nonetheless.
While the stock cable was fine and I used it for quite a while, I finally paired it with the Satin Audio Gaia II, the SPOCC pure copper type-4 litz cable from Satin Audio’s entry level Titan series. Further impressions of Horizon will be with this pair.



Where was I? Oh yes, as I said before, Horizon, in spite of being a V shaped iem, really really captivated me. Now, how did it do that? Well, you see, I was getting bass that was thunderous to a fair degree, and yet a highly transparent midrange, crisp and slightly sharp notes, etched out details, brilliant separation, superb layering & imaging, three dimensional soundstage, and extended sparkling & quite energetic highs (which can make or break it, depending upon tolerance)...it was rare to find all of them together at around $300 mark, so don’t blame me for being enamoured with them! The complete presentation was so dynamic that it shook me to the core and made my foot tap all together!



Let’s get to the details. Firstly, as already mentioned several times and is quite evident in the graph, it boasts a big and bold Bass. There’s no favouritism here - Mid and Sub, none of them are favoured over the other. Both of them are boosted quite a fair bit, as can be clearly seen in the crinacle’s graph: a clear 12 dB boost from 1khz. And every bit of it can be heard and felt. It slams quite powerfully, digs quite deep, exerts quite a respectable amount of pressure, and reproduces textures with authority. Each drum hit is felt. The bass guitar riffs resonate deep within your soul. And yet never they become muddy or overlap one another. A brilliant track to check is Deep Purple - Chasing Shadows. There’s a unique rhythm here, consisting of drums, timbales, maracas, cowbell, along with a clearly pronounced bassline almost throughout the track. The drum and timbales hits are thick and commands a quite strong presence right from the onset of the track. And shortly after the bass guitar comes into play, exerting full bodied notes and deep rumbles. However, never once the drum hits and bass guitar rumbles overlap each other or get mashed together - such is the brilliant control and outstanding textures. Being this strong and thick, one would think that the bass will be one note, but that is the farthest from the truth here - the variation in the bass guitar tones are clearly produced and easily noticeable; there’s a clear distinction between the drum and timbale notes as well. This shows how refined the bass is.
To get an idea of the extent of the low end, I played Bear McCreary-Battlestar Galactica Season 2 OST: Prelude To War. This track has some serious bass drums that slam and rumble in a thunderous way that shook me to the core. And never once did I feel the textures became overshadowed by the thick bodies of the notes. There are also some bass at play which set up a firm groundwork for the track with equally formidable presence.



One would think, given how deep the Midrange sits behind the bass, that its midrange performance will be quite substandard. And in fact, I felt the same when I was reviewing the Ikko OH10. The curves of Horizon and OH10 are pretty similar, and the midrange performance of OH10 was not anything remarkable. However, the handful of reviews of Horizon that I could find, not one of them bashed it for being unimpressive. And once it started playing, I can clearly hear why.
Immediately after the powerful bass the aspect that stands out the most is the highly clean and clear midrange. The first defining trait that I can detect is precision. It’s rare to get to hear such a cleanly defined and well separated midrange in this price segment. The strong low end never meddles into it, albeit it does add some weight to the lower mid which is highly welcome. There is an edge in the midrange notes which helps to enhance definitions, which is one of the notable aspects of it. One might say it’s prone to being clinical and dry, but thankfully the DD timbre barely saves it from that…but yeah, ‘barely’. Compared to my other DD iems, the midrange definitely feels a bit lean, and yet not that lean to abandon musicality. Lower mids, especially deep male vocals still have that touch of throaty sound which make them sound natural, but as it goes upwards the edges in the vocals can be detected, especially in the finishing notes, and they do sound slightly less organic then - a bit more digital. There seems to be a slightly metallic sheen in the vocals. All these can be experienced in the track Leonard Cohen - Hallelujah; here his voice starts deep and weighty, but as it soars the sharp edges become a bit accentuated. Rasp and harsh male vocals, like in Metallica - Enter Sandman and RHCP - Dani California sound a bit edgy, but not overly thin and unnatural - an acceptable amount of note weight is still present, but not exactly up to desirable degree (I hope this makes sense.) But come to smooth and baritone vocals, like Neil Diamond, Bob Dylan, they sound nothing short of delightful. Sure, I would have preferred slightly more body, but that’s really just me fussing over it, as the DD timbre makes them quite enjoyable nonetheless.
Coming to female vocals, well, Horizon bestows them with a brilliance and extension which perfectly conveys the emotion in them. Be it Whitney Houston,Madonna, Julia Jacklin, Amy Lee, Christina Aguilera, Cherryl Wheeler, Pink, Yao Si Ting, Charlotte Cardin…all of them sound alive and appropriately full of life. The smooth ones have that sublime depth, the energetic ones soar high with surreal radiance. They do have one thing in common - all of them have a silky nature added to them, which makes them all the more magical. Following the trait of the male vocals, here also the sharpness might sometimes work against the female vocals, and accentuates the peaks occasionally to become slightly piercing and adds that metallic sheen to them, but thankfully that happens in very specific tracks only, and that too quite seldom. However, as I played Sara Bareilles through Qudelix 5K, the peaky parts of her voice became really uncomfortably accentuated and sharp, slightly sibilant, and ultimately not enjoyable at all. Yao Si Ting in Scarborough Fair also had one or two sibilant areas that got slightly piercing for a moment or two.
On the other hand, the instrumental tracks sound outstanding. Each instrument notes sound well defined, details are effortlessly brought out. The slightly sharp notes help here a lot. Especially string instrument notes, such as guitar (both electric and acoustic), sound crunchy. Despite having the sharpness, the notes do not feel dry, and most certainly not flat. May be very slightly thinner in body, but that assists in improving the separation rather than making it unnatural. The most notable aspect of Horizon here is how effortlessly it recreates the detail in the instruments being played in the far background. Despite being in the background they do not feel muted and washed out, rather the microdynamics of them are brought forward quite nicely and I never failed to notice them. Don’t misunderstand, though, it’s not like the background instruments are pushed forward in your face, that will kill the stage depth. They remain situated at the depth of the stage they are meant to be, just they sound quite clear and stand out so prominently that the details become really easy to pick up. This is precisely the reason why I love listening to orchestral and instrumental tracks the most with Horizon, for e.g, James Newton Howard - Red Sparrow OST: Overture, Cloud Atlas OST: Won’t Let Go, Estas Tonne - Strings Of A Bard, Hans Zimmer - The Dune Sketchbook.



The Treble of Horizon has a considerably bright and slightly cold nature, despite the steep 20 dB roll off past 8 khz. It still has plenty of energy in the region of 6 khz-8 khz. The high frequency notes have a silky nature, however, they’re not silky SMOOTH…rather silky and sparkling, with slight edges here and there. The utter transparency of the midrange is carried forward to this region as well. These two aspects combined really elevates the treble to an ethereal presentation. The cymbal and hi-hat notes stand out quite well in the mix, even in the busiest tracks. However, this is purely my guess, because of the steep roll off past 8 khz, they never become uncomfortably piercing. Again, this is purely my guess. The crash cymbals notes sound brilliant in the mix and the subsequent decay is quite natural, but even on tracks where the cymbal crashes are at the forefront, they never become overly piercing. I never had to wince once in the tracks Tool - Stinkfist, Red Hot Chilli Pepper - Dani California, Metallica - Enter Sandman. Specifically, Enter Sandman has a constant hi-hat roll placed quite forward, which has an abundance of sparkle and energy, and never once I had the sensation of getting stabbed in my brain with several icy needles, even though they retained a strong presence throughout the track. In Stinkfist and Dani California various cymbals notes are placed in various depths of the stage - some in front while some come from back in the scene. Horizon, while portraying the frontal cymbal notes with sufficient energy but not uncomfortably bright, also manages to bring out the background treble notes to their justified presence. The background treble notes - cymbal crash, ride cymbal roll, or cowbell - everything becomes clearly discernible in the mix, at their respective position, with sufficient details. Even the faintest of notes sounds clear. The layering of the different notes is masterfully carried out.
Granted, there is a spicy nature due to the edgy notes and perhaps a metallic sheen…but then, treble notes generally originate from metal to metal collisions, so the metallic sheen really did not prove to be detrimental for them, at least to my ears. The sharpness of the notes also remains somewhat within control so that they never become too spicy to sound wrong. However, for treble sensitive ears I can clearly see it may provide notable discomfort, as despite the absence of piercing peaks, the general abundance of energy can get a bit overwhelming. For treble heads, well, you’re in for a treat.
Post 11 khz the treble peaks up and recovers some energy, which helps in retaining the air in the treble region. The multiple different types of treble notes never fight among each other to gain prominence - all of them are well separated and have enough room to breathe.



I believe I have already said enough regarding the several aspects of technicalities of the iem. The stage is sufficiently deep while having a nice width and height, imaging is quite pinpoint and accurate. No need to repeat after myself any more.

Conclusion:
Let me be perfectly clear - Azla Horizon is not a safe choice for everybody. It is very much a specialist iem. Such a sharp V shaped iem at about $300 range ($286 to be exact) is not what most people are looking for at this range. A 12 dB boost in the low end over 1 khz, and a similar boost in the upper mid frequency generally gives off a lot of red flags. And truth be told, I would have definitely preferred a bit less emphasis in the 5khz - 8khz range; however, it is what it is. In spite of so many alarming aspects, Azla managed to tune the final sound in such a way that has definitely drawn me towards it. And that’s where it distinguishes itself from other V-shaped tuning iems. The highly transparent midrange with captivating instruments, just right male vocals, ethereal female vocals, brilliant treble, airy and spacious presentation, immaculate imaging, and all over a very dynamic and engaging sound do not take much time to capture the heart of the listener, the way it did mine, despite the slight nagging of the sharpness of the notes. I cannot recommend it to anyone as a blind buy suggestion, because it takes time and a certain level of tolerance to bright tuning to really adapt to its sound signature and appreciate it. But quite honestly, those who do have these two, would find satisfaction in it - that’s one thing I can swear on. It has become my EDC (every day carry), paired with Qudelix 5K or occasionally L&P W2. The Hiby Lasya is a calmer sister that compliments it. When on the road and I need that energy, that power, to drown out the outside noise a bit to enjoy my music, Horizon fills in that role perfectly for me.

Since this was a review sample, the retail packaging was not available. I received the iem, the eartips, the carrying pouch, the earhooks, and the literature.



Build and Fit:
Chu is rather solidly built with a fair amount of weight that really seems surprising given the small sizes of them. However, that makes it unnaturally heavy which totally was not required in my opinion as I don't think it has anything to provide to the actual acoustic tuning.
Although, because of the small size, the fit is rather snug and nice.

Sound:
Chu has a largely neutral sound that is quite clean and has ample amount of brightness. The lower end has some slam, but not enough power with the stock Spring tips. Hence I changed to some narrow bore IMR tips I had lying around, and the sound improved a bit.

Do note that I have tried to record my impressions below while keeping its price point in mind.

The first impression that comes to mind regarding Chu’s sound is that it is a bit on the thinner side. With the narrow bore tips there is finally a bit of a boost in the lower region to add a bit of slam in the midbass. Subbass has a bit of warmth and the rumble cannot be missed, but it still feels a bit restrained. Textures are nice for the price, does not feel washed out. Bass drums do not feel as attacking as they should, and kickdrums also are a bit restrained.
Mids sound quite clean, but also is pretty much lean, which enhances the clarity and transparency, in exchange of a bit of engagement and musicality. No, Chu most certainly is not an analytical iem, and sounds a bit musical also, but not to the point that I start to groove with it. The transparency is commendable though, and really helps to improve separation. I really could not find any fault on that front, given the price. Male vocals do have that DD timbre to avoid sounding unnatural, but they still do sound thinner than my preference. Same occurences are noticed for guitars, snare drums, etc. - they just do not sound full enough. However, they do sound quite crisp which makes them easier to notice and appreciate. Although, it most certainly is not that much V-shaped that the vocals feel further away than the bass; rather, they sit a bit closer and have a nice presence. Female vocals on the other hand have quite a nice amount of brilliance and energy to sound vivid...which is quite enjoyable. Chu also makes sure not to make the female vocals sibilant - another feather to its hat.
Now comes the treble, which I found the best part of the package. It's energetic and sparkling with respectable extension, and yet never feels particularly harsh or piercing. It has a rather cooler hue, which syncs nicely with the overall neutral tonality. Nice amount of air and transparency are present here. Cymbals and hi-hats sound really crisp and bright without being piercing. The only gripe I have here is that it sits quite forward and almost in line with the bass, which gives rise to the lessened depth of the stage, and subsequently portrays the stage as rather flat.



Conclusion:
There are numerous weak points here that I can note down. However, once you remember that the price is just $20, most of your arguments will just stop at their tracks. Then, I cannot but marvel at the quite clean presentation it pulls off without sacrificing the bass much. I love an energetic sound and CHu also provides that in spades. Yeah lean mids is a big no no for me, but the DD timbre saves it somewhat this time. Pretty solid recommendation in this price range to be very honest.

Introduction:
It’s a new seasonal offering from BQEYZ, the Autumn! From the very first look of it I fell in love with it - such a beautiful elegant look! Coupled with it the mention of a 13 mm DD inside surely had me interested…and the swappable magnetic filters were a fresh and unique addition. So when Elle from BQEYZ offered me the Autumn for a review, I could not turn it down.

Disclaimer: I was provided this BQEYZ Autumn as a review sample from BQEYZ for free in exchange for my honest impressions. The impressions recorded below are completely my own and not biased by any manner.

In the Box:
The beautiful black and orange box looks beautiful and compact. Inside are the iems, a 2.5mm balanced termination cable, a small BQEYZ carrying case with a cleaning tool inside, the magnetic tuning filters and the filter changing too, and 2 types of eartips - small bore and wide bore - 3 pairs each. Nothing flashy, just the necessary elements. Liked it.
The cable is really quite nice though - soft and supple. Quality is not bad either.



Build and Fit:
The very first aspect of Autumn that draws attention is its build. The matte finish blackish blue body coupled with its signature subtle curves looks very premium while being fairly lightweight. Even though light, I never had a feeling that it can have a tendency to fail by the slightest impact. Quite faith inspiring build.
However, following my legacy with BQEYZ iems, I struggled to get a secure fit with M sized tips. It’s only with L sized narrow bore tips that I could have a good fit. However, it still was not the best.

The magnetic filters have already been talked about extensively, so I need not focus on how extremely convenient and effective they are.

There were 2 different sets of tips with different bore width. I went with the narrow bore for my review.



Sound:
Autumn is a very joyous season for me, without much flamboyance. BQEYZ Autumn apparently follows the exact same methodology in reproducing the sound. Whenever I put it on, I can feel a calm and content feeling. However, the content does not linger if an energetic track comes around, and Autumn cannot perfectly portray that energy…but apart from that, for the rest, I did not have many complaints. Autumn has a distinct warm tonality which is quite pleasing and forgiving. The sound is quite clear. The dynamics take a hit though, but let’s save it for later.

Before coming to sound, some words regarding the filters need to be said. You see, I started with the normal filter, but felt that the top end was a bit too muted, and hence I put on the Treble filter, and never went back. Trying on the Bass filter was practically useless for me, hence I did not give it much thought. But I did put it on once to get an idea of how much the bass increases, and it did increase noticeably.

To start with the Low End, let’s say it gets the job done. I cannot find anything to bash about, nor did I find anything to boast about here. Midbass is favoured a bit more here over the subbass, which isn’t entirely overlooked by the way. Subbass rumbles have above average body, and have a slight bit of pressure to hint at the presence. Midbass slams have slightly more emphasis here, however, the impact is a bit slow and the notes are slightly on the thicker side. The slams have volume, but the attack feels a little soft, and hence has a bit of a pillowy nature to it. Textures are not bad. Overall, with the treble filter, the low end feels rather polite and controlled - which can be hit or miss depending on track.

The traits mentioned above become mostly apparent on the fast kickbass of Metallica - The Four Horsemen, the hits feel thick, but not as attacking as I would have liked.

The bass drums in Battlestar Galactica Season 2 OST - Prelude To War have a very nice reverb, but the initial attack is a bit restrained - which makes the stage cleaner, but lacks the engagement factor.



Midrange is where the strength of Autumn lies. There are a lot of positive aspects here - the notes are smooth, the midrange has forward seating, and overall sounds quite transparent. The one aspect that becomes evident is how the individual notes have a controlled presence. They are not overly thick to sound natural while eating up space, not overly thin to sound unnatural and shrill while opening up more space - they are just at the right balance of both. What’s more - the notes have no untoward peaks at all, so at no point of a listening session you will experience discomfort, however rough the track might be.
The percussion instruments (snare drum, tom tom) sound crisp enough, but not exactly striking. Notes are slightly on the thicker side, which does not play negatively in case of instruments, while enriching the male vocals to have that throaty presence. On the other hand, the female vocals slightly lack that brilliance, and do not portray the energy and excitement completely. However, they do not sound dull.
But the most notable aspect is how clean the midrange sound despite having a smooth presentation. Nothing sounds muffled. However, the smoothness comes with its own caveat - the notes do not have much bite, and hence that spark of life feels missing a bit.

I listened to a busy track Eluveitie - Slania to confirm the transparency, and it also confirmed the lack of bite. However, Leonard Cohen sounded quite natural in the track Hallelujah. Yao Si Ting, as I mentioned earlier, sounded fatigue free but also not as brilliant as she should be in the track Scarborough Fair.



High range is tuned to play a supportive role, not as a main character. There is an evident control present in the lower treble region that prevents it from being splashy or piercing, but the tonality is preserved well while doing that. Treble is not dark at all, rather have an above average amount of energy coupled with an added smoothness. Upper treble extension is above average, which makes the treble sufficiently airy. The shimmers are present, but following the smooth tuning does not sound crisp enough. Not a deal breaker, in my opinion, for someone who prefers this type of tuning.

Regarding Technicalities, let me start with soundstage first. Autumn portrays a nicely wide stage with a quite open presentation. Height is above average, but the depth is about average, which makes for rather an average imaging at best. A bit fuzzy and two-dimensional - that is how the imaging is. However, the clean stage and transparent mids helps to keep the presentation enjoyable yet. Details may seem a bit less pronounced due to the smoothness, but again, musicality takes lead here. An extremely laid back presentation, which also means the macro dynamics are severely compromised. The overall presentation is simply not dynamic at all, but rather suitable for when you just need to relax with some good music.

Conclusion:
I have said all I have to say about Autumn. From an objective point of view, Autumn is a brilliant set of iem for those who like this sort of signature: laid back, open, airy, smooth, and musical. Me? I prefer some excitement in my life. More vibrancy, more macro-dynamics, more bites in the notes. So, no, BQEYZ Autumn, despite being a maturely tuned iem, is not for me. But that in now way means that Autumn is not recommendable. I would recommend it in a heartbeat to anyone looking for a iem for a comfortable listening session.

Introduction:
When Tanchjim first anounced OLA, I took an instant liking to it because of its unique shape and small size. In the world of iems, the offerings from Tanchjim are generally held in high regard - Oxygen, Hana 2021. Did not hear much noise regarding the Darling or the Prism, but may be because of the price points. I have experienced the Hana 2021 and took an instant liking to that. However, I did not have much hope for OLA regarding the sound given the rather weak low end response, as seen on various measured graphs. And yet, when @shenzhenaudio reached out to me for a review of OLA, I could not turn it away simply because of my curiosity. Who would have known how I would fall for it...



Specification:
Sensitivity: 126dB/Vrms
Impedance: 160± 10%
Frequency range: 7-45kHz
THD: < 0.3%
Driver: 10mm dynamic driver
Cable: 1.25M 3.5- 0.78PIN
Technology: DMT 4
Cable Material: Double-Core OFC Core sandwitched with Kevlar fiber
Diaphragm material: polymer graphene

Disclaimer:
I was provided this unit by Shenzhenaudio for free in return of my honest opinions. My opinions recorded here are not influenced by any means and are completely of my own.



In the Box:
The box of Tanchjim OLA is a compact one with an anime girl photo on top (that seems to be the trend nowadays.) Inside, there are the iems, the stock SPC cable (with mic in my case), a soft cloth carrying pouch, two sets of eartips - one for bass enhancement one for treble enhancepment, or, in simpler words, one narrow bore and one wide bore set.



Build and Fit:
I have not yet encountered another more lightweight iem. The aerospace grade aluminium looks sleek and premium, without addind almost anything to weight. The PVC shell does not look cheap either, and clear view of the inner DD really improves the aesthetic. The bright silver cable adds to that. Everything together certainly creates an elegant visual impression.

Point to be noted here is, there is a general misconception that the cable is a Silver Plated OFC cable. However, as per the description provided by Tanchjim:

Which means the cable is essentially a OFC cable, and the outer silver plated OFC wire is just for aesthetic purpose and strengthening of the cable as it "does not participate in electric conduction."

Fit is another story. For my ear, only the L size Narrow Bore tip gave me a somewhat secure seal and somewhat comfortable fit. The nozzle, even though having the impression of being long, because of the unique shape of the shell, does not reach very deap, and hence getting a comfortable fit with secured seal becomes almost difficult. For the other record, my other usual aftermarket tips failed to give a secure fit.

Sound:
The whole focus here seems to be on producing a vivid and open sound while preserving as much body as possible in the low end to preserve the naturality at bare minimum satisfaction level. Tanchjim has achieved this with exemplary finesse. Tonality is decidedly neutral, however, still quite pleasing.



Talking about the Low End, well, the subbass isn't anything to write home about - it's not very well extended, does not have much pressure hence not much tactility. And yet they do not sound lanky and thin. How to say it...I could clearly hear the subbass rumbles, and the note weight was just ok, but I did not feel any aversion to it for sounding thin or unnatural. Yes, I could not feel that pressure, but that was a trade off I readily accepted. The textures are well reproduced though, so props for that. And frankly, while going through my test tracks, I found that while on some tracks the subbass roll-off DID bother me, on other tracks I simply did not notice - which might be the way my brain adapted to the whole sound signature.

I would like to focus on a few tracks here:
Battlestar Galactica Season 2 OST: - Prelude To War In this instrumental track, the bass drums digs deep with long decay and they really need that subbass focus to sound natural and have that body. However, OLA failed to capture that due to the rather limited extension. The drums can be clearly heard, but not felt. That thick body from each note sounds missing. While the slams do not sound that much lean or lanky, they do sound a bit cut short, due to the fast decay. And also, that sheer force behind each slam also sounds rather restrained.

But now I come to Massive Attack - Teardrop, and suddenly, I do not feel that much discontent any more. The electronic bassline is very much enjoyable with very good texture and sufficient body, although the pressure cannot be felt, as it cannot be felt in The Dark Knight OST - Why So Serious?

And then, the bass guitar pluckings in Leonard Cohen - Hallelujah and the bassline in Evanescence - Imaginary and Red Hot Chilli Pepper - Dani California does not sound weak at all, rather they struck a very nice balance between having a nice weight and staying just north of neutral. Sure, they do not touch the inside of your soul, but they move you nonetheless. What's more, you can clearly distinguish the textures because of the clean reproduction.

However, all of the shortcoming stated above are compensated by the brilliant midbass, which has a very nice amount of slam and, most importantly, body, not to feel weak or unnatural. Kickbass hits are just enough full not to sound hollow, while not being overly fat either. Most of all, it does NOT sound like a BA, the goodness of natural DD timbre is very much present throughout this spectrum. Tanchjim truly has tuned the low end incredibly well - while most certainly not given the highest priority, not compensated in the presence either. A masterfully tuned low end that is fast yet impactful, sounds natural, and absolutely stays out of the midrange's way.

My go to track here are Metallica - The Four Horsemen and Red Hot Chilli Pepper - Dani California. The fast kickbass in the former and hard slams in the later sound quite impactful and enjoyable. However, when I played Eluveitie - Inis Mona, I felt the kickdrum hits were may be a wee bit hollow, but it may be the recording.



Coming to Midrange, well, it's the very definition of neutrality at this price. This is where the whole focus lies. What will make you instantly go WOW is the sheer transparency the midrange boasts. The insanely open and clean presentation is nothing short of cathartic; there's not even a hint of congestion anywhere! The tonality is neither warm nor cold. Guitar, violin, piano, snare drum - everything sounds clean, crisp, natural, well separated, and most of all all of them seem to have an evenly distrubuted emphasis so that there is no infighting going on for grabbing the focus. Notes are crisp and has a certain amount of bite that helps in capturing the attention, and yet there is never any uncomfortable peaks throughout the upper mids and lower treble region. Notes are so cleanly separated that the sense of airiness just takes your breath away. Especially on busy tracks OLA shows its prowess.

For e.g, in the track Poets Of The Fall - The Ballad OF Jeremiah Peacekeeper, the brilliant ensemble of violin, acoustic guitar, bass guitar, snare drum, and backing vocals is rendered so beautifully that it simply made me awed

Male vocals won't certainly make you weak in the knees, and yet doesn't sound lean and pale - just the right amount of fullness is there for the natural tonality. They do not sound lean, just the right amount of fullness, and still have the bite to grab the attention. Female vocals are brilliant and captivating, soaring high with energy. The occasional peaks that are presented in the recording are hinted at, but never emphasised, so they never become uncomfortable.

My staple track for checking the body of male vocal is Leonard Cohen - Hallelujah, and OLA passed that test with flying colours - Leonard Cohen's voice sounds deep and full bodied and very well textured. A very similar experience I had while listening to Poets Of The Fall - The Ballad Of Jeremiah Peacekeeper, Mike Saaresto's voice sounded throaty, textured, and emotional.

For female vocals, I went to Yao Si Ting - Scarborough Fair. Yao Si Ting's already brilliant voice sounds even more ethereal and dreamy, while having a distinct spicy sizzle that might prove to be sibilant on other bright IEMs, but not on OLA, no, OLA reproduced those sizzles and yet kept the sibilance at check. When Amy Lee sings the track Evanescence - Hello, the pain in her voice comes alive through her voice, and as her voice soars upwards goosebumps rises.



The High range certainly isn't overlooked to focus on the midrange, and yet, to my utmost surprise, it is not unnecessarily boosted to create the sense of airiness either. No, the airiness is already so prevalent that Tanchjim only had to tune the treble in a way to maintain the brilliance at an acceptable degree while making sure not to cross over to the uncomfortable peaky regions - and they passed the test with flying colours. High frequency notes have quite the sparkle - sounds crisp with a tad bit less energy than the midrange (which isn't a deal breaker for me.) The fact that it doesn't compete with midrange to be in focus of the presentation, and yet makes its presence distinctly felt, is what makes it a masterful tuning. Upper treble extension is quite good, while trebleheads might long for a bit more energy there. Lower treble, as stated above, sound crisp and clean, has the right amount of bite and energy, while maintaining a presence slightly behind the midrange.

I played Steely Dan - Do It Again, and the constant background light cymbal hits were brought into notice very nicely by OLA. The crash cymbal rolls also sounded brilliant and extended well with a nice decay.
Red Hot Chilli Pepper - Dani California has some aggressive cymbal and hi-hats at play which sound brilliant but never overbearing.



Now, let's come to the Technicalities. Regarding the Soundstage, well, I was dumbfounded. The stage is W-I-D-E for its price, if not the widest at this range. A quite out of head experience, it is. While it does not extend that far in the depth region, it still does to some extent. The height is nice, helping to create a quite well rounded soundstage. Most importantly, as the instruments are not fighting with each other to gain focus, a very nice headspace is created with precise imaging. The brilliant Separation between the notes aided into this even more.



Conclusion
If it's already not very obvious, I'll say it again: I freaking love it! Tanchjim has literally hit it outta the park with OLA. They have my confidence now, and I'll surely follow them closely from now on. Anyone who knows me knows I love my bass, especially subbass that reaches deep and vibrates in the chest, coupled with juicy midbass slams. OLA has none of those traits - the bass is rather on the fast side, with just enough midbass body that the slams do not feel hollow. However, the other aspects have blown my mind so much that I am not missing anything, anything at all! It's at the peak of neutrality and balance under $50, and I just get lost in the music without having to think about the bits and pieces.

Introduction:
A new year, a new Kinera to join the fray, with a fresh set of driver combination. And I must say, it is a looker indeed! Just like its predecessor Norn, it has got a similar, if not better, breathtaking visual appeal that captivates the attention instantly. I will not go into details of the history of the name and all, as those can be easily found on other websites. I got the chance to audition and review it thanks to Hifigo.

https://hifigo.com/products/kinera-urd-1

Accessories:
The unit came in its carrying case with the cable and 1 set of Final-E type eartips. The carrying case looks quite premium with its fabric outer shell and Kinera written on top. The cable looks quite mesmerising with the gold and silver stripes. What’s more, the cable is of swappable plug type, and 3 plugs are supplied alongwith - 3.5 mm SE, 2.5 mm balanced, 4.4 mm balanced. That’s a whole lotta option for anyone out there. The tips that were provided with the package were the Final-E type tips, so no idea if other tips were also provided. I did not tip roll.



Build and Fit:
As already mentioned, the all resin body looks stunning to say the least, and has somewhat of a perception of depth on the faceplate. Moreover, on the sides, the aquamarine parts sparkle under light that looks absolutely stunning. The shell size is not too big, but quite thick and it sticks out of the ear. With the provided tips the fit was quite secure. There is a bit of a vacuum build up inside the ear though, which can be a bit disconcerting in the beginning, but after a while the feeling goes away.

Sound:
The first term that came to my mind regarding Urd was that it was very safely tuned, while keeping focus on not to wash away the details. The tonality was obviously warm, a bit beyond my preference but that is not necessarily a bad thing. The one positive aspect of its tuning is that it is a very comfortable sounding iem which will not make you miss out on the technicalities a whole lot also.



As the specs say, the Low range is handled by a dual diaphragm Dynamic Driver. Anyone would expect that it will pack a solid punch in the low frequencies with deep subbass. However, to my ears, that was not the case. Now, it can be that the pairings were at play, but even then, the innate characteristics of the driver cannot change that drastically by change of source that will completely transform to being juicy from dry. The subbass of Urd is a bit too early rolled off to my ears, which allows you to listen to the subbass rumbles and reverbs, but does not allow you to really feel it. Midbass slams are definitely punchy, however, the rather controlled subbass does not add enough body to the midbass notes to feel lively or tactile. On the other hand, this also guarantees a very clean bass with easily perceivable textures and details.
A point to note here - the satisfaction level of bass also changes depending upon the instrument being played. For example:
The kickdrums in Metallica - The Four Horsemen sound good enough - fast and punchy while not taking up the centre stage. But, the same cannot be said of the bass drums in Battlestar Galactica Season 2 OST - Prelude To War or the subbass rumbles in The Dark Knight - Why So Serious: The pressure and reverbs were not present in satisfactory quantities.

The BA driver handles the Mid range rather well, in my opinion. If the BA timbre can be overlooked, the notes it produces are detailed enough while devoid of any unnecessary peaks. A rather smooth yet crisp midrange that can work for almost anyone without much offense. Musicality is well preserved here. The added warmth makes listening to male vocals a pleasure. However, the female vocals may seem a bit too warm to have that euphonic touch to them, but nevertheless, that is not a deal breaker and they still sound sweet enough. Trying to remain as neutral as possible while ignoring my obvious bias towards DD timbre, I can say that the lower midrange has struck a balance between having sufficient body not to sound too lean, while maintaining adequate amount of crispness to provide excellent separation as well. The upper midrange is tuned rather safely while smoothing down the peaks to provide the most comfortable experience.
Snare drums and guitars (both acoustic and electric) sound crisp and clear and very easily identifiable in the mix. Bass guitars may lack a bit of body, but do not sound particularly weak. Cellos sound distinct and present in the mix without being excessively fat. However, with the smoothness comes a caveat - the midrange lacks any kind of bite. It does not really grab your attention or make you feel engaged - but that is completely a case of personal preference.
Some test tracks:
Battlestar Galactica Season 2 OST - Prelude To War
Eluveitie - Inis Mona
Evanescence - Imaginary
Leonard Cohen - Hallelujah
Yao Si Ting - Scarborough Fair

What surprised me was how the EST driver handled the High range. I had my previous run in with EST drivers in TSMR Land, and the high frequencies were exceptionally energetic there with brilliant extension. Moreover, Land had a dedicated BA driver for handling the high frequencies along with the ESTs. Here, however, as claimed by Kinera, the High range is solely controlled by the 2 EST drivers themselves. I was expecting a rather sparkling high range with plenty of energy…but was a bit surprised when I was presented with a rather smooth sounding one. It seems as if the EST drivers are dutifully following the midrange BA driver - no peaks or harshness throughout the spectrum, while still sounding crisp enough to provide above average separation. Cymbal hits do not get splashy or piercing at any moment. The tonality is also a bit on the warmer side, and hence the excitement may sound missing from the treble region, which may or may not be an issue depending upon preferences. Extension is decent enough that the ride cymbals in the background do not sound muted.
The drawbacks of the treble of Urd has to be the missing sparkles and a bit of air between the notes, but that’s all. Personally, such a safely tuned treble response is not at all up my alley, but I am trying to keep this review as less emotional as possible.
Some test tracks:
Eluveitie - Inis Mona
Steven Wilson - Pariah
Red Hot Chili Peppers - Dani California

Urd does not skimp on Technicalities, but does not particularly excel either. Given the very controlled low range, a well separated smooth mid range, and a similarly smooth yet extended high range, it manages to create a very open sounding atmosphere with above average imaging. The stage is unmistakably tall, and the height is a bit more compared to the width and depth, so it sounded a bit odd to my ears at times. However, there is one aspect of Urd that I did not like at all - and that is the dynamics. Yes, micro-dynamics were good enough, but the macro-dynamics was considerably compromised in my opinion by way of the too safe tuning. There simply is not enough life to the music, the dynamic nature is meticulously avoided to obtain a rather laid back presentation. It was definitely intentional, and I do not want to put it down because of that simply because it does not suit my particular preference.



Conclusion:
I would like to finally take the liberty here to be a bit more emotional than purely objective. Does the Urd suit my preference? No. Urd lacks that visceral and tactile low range, the authoritative and gritty, full-bodied midrange, and a sparkling energetic high range. Urd is the total opposite of that. It is not a very dynamic sounding iem, the notes do not bite enough, the engagement factor is missing, the overall sound is so safe that it’s borderline dull! I could not connect to the music emotionally at all. However, I can understand that for someone who is looking for precisely these aspects in a iem, Urd can be a very nice choice. For me, it was a hard pass.
