The Racing Orange package is impressive, featuring a stunning array of accessories from the large case to the extensive selection of tips and a durable and robust modular cable. It's likely worth the cost for these items alone.
The DUNU Titan S2 is a single dynamic driver universal IEM with a bit of a twist.

The device features a distinctive dual chamber and dual magnet dynamic driver with a high-rigidity diaphragm, which guarantees more accurate sound reproduction across the frequency spectrum, while also enhancing driver efficiency and responsiveness.
The Titan S2 boasts an impedance of 16Ω and an SPL of 107 dB/mW (@1kHz), indicating that it is a relatively easy pair of earphones to power using most portable devices.
Additionally, it comes with DUNU's Q-lock cable, a versatile plug cable system that includes both 3.5mm SE and 4.4mm balanced plugs.
I personally appreciated the fit and finish of the S2 and found the comfort and isolation to be good.


The bass produced by the Dunu Titan S2 is deep and impactful, offering a satisfying rumble that maintains clarity without overwhelming the mix. The pronounced presence of percussive elements, like crisp snares and robust bass, is a hallmark of its U-shaped sound signature.
The midrange of the Titan S2 is warm and rich, offering a fine level of detail, though the note weight is thinner, and the musicality less than I would prefer. However, this doesn't mean they are poor; like most U-shaped IEMs, the mids are well-defined, and the technical proficiency of vocal performances is quite good, even with a slight recession.
The treble on the V2 closely resembles that of the original, with well-controlled and refined upper frequencies that are bright and crisp, offering good detail and spaciousness. It complements the warm bass and mids, adding a pleasant tonality to the overall performance.
The Titan S2 stands out for its imaging and instrument separation, allowing for precise sound placement within the soundstage and guaranteeing that each note is articulated with detail. It lends itself well to games and media.

Afterthoughts: The Dunu Titan S2 stands out in the budget category, offering a U-shaped signature that delivers ample technicality and detail with an enjoyable tuning. Although it may not be the most robust or fun, it remains a highly enjoyable option, providing excellent value for all that is included.

Let's begin with the all-black packaging, subtle and understated, yet inside it contains two different types of eartips, a silver cable, and a large case. Regarding the cable, although well-made, it is thin and seems mismatched for this IEM. However, the sleek etched design of the all-black IEM, with its metal and resin build, feels premium and durable. I found them to be comfortable, and they provided good isolation, especially considering the short nozzles.

Sound impressions:

We'll begin with the lower end and progress upward. I have a personal preference for the P20.

The bass offers a pleasing deep rumble and quick recovery, making it one of the fastest planar IEMs I've experienced. The mid-bass delivers a tangible impact, and the bass overall is smooth, well-defined, and characterized by both speed and accuracy.
The midrange on the P20 is warm, with vocals sounding exceptionally realistic with good texture and weight, especially male vocals. The vocals are generally smooth, and their placement is well-executed. I appreciate the natural tone and timbre of the P20; however, there is a slight tininess in the female presentation and upper mids. Despite this, they sound realistic and remain very pleasant overall.
The treble of the P20 leans towards a relaxed presentation, offering just enough energy, airiness, and sparkle. However, for some, it may appear dull and slightly dark. On one hand, the highs sound very good and clean, yet they lack definition and character. While this is not a treble-focused IEM, it does offer good air and a decent level of detail.

Soundstage and technical aspects: The P20 provides an average to above-average width of soundstage, and it is notably deep. It has decent separation and layering, although the positioning is average and not well-suited for gaming..

My Afterthoughts:

The Shozy P20 is a well-rounded planar IEM that offers a decent balance of technical prowess and smoothness. It will definitely be a contender for a solid all-around IEM, particularly in the planar segment of the market.

The Simgot Super Mix 4 is presented in a glossy green box, featuring an internal view of the distinctive IEM and comprehensive documentation on the back. The design is subtle, featuring a matte faceplate and a glossy resin body, complete with a gold circle on the front. The case is large and can accommodate a lot more, which I appreciate, and the cable is attractive and sturdy. However, I wish it included bore tips of various sizes. I found them comfortable for extended use, and the isolation was very good.

Sound:

Bass:
The Bass of the SM4 is deep and well textured with a slower response in the Sub-Bass but not overly so.
The bass is tastefully enhanced, with a focus on the Sub-Bass response. While it may not satisfy those seeking Bass Head quantity, the depth provided should be enjoyable and fun to most. The mid-bass has sufficient punch, and although it may not be the epitome of definition and impact, it presents a natural and captivating sound. The bass significantly contributes to the Supermix 4's warm tonality, yet due to the quality of the drivers and the tuning, it remains well-balanced with the midrange and treble.

Midrange:
The midrange is warm, and like most Harman products, it leans towards a sound that is slightly above neutral. The mids have a warm, rich signature, overall providing a very smooth and engaging experience, with the upper mids being slightly brighter and sharper compared to the lower midrange.

Treble:
The high tones offer balance. Although they may not be the most shimmering or bubbly treble, they deliver sufficient clarity and definition. There is just enough vibrancy to complement the warmth of the bass and midranges without becoming harsh.

Soundstage:
The Simgot SuperMix 4 delivers an impressively wide, deep and tall soundstage with outstanding resolution and precise imaging. It shines in retrieving details while maintaining a warm tone. The spatial precision and depth allow for easy discernment of instrument and vocal placements within the stage's confines. This would definitely work well for games and movies.

Afterthoughts:
The Simgot SuperMix 4 is a distinctive IEM that features four different types of drivers and a highly competent crossover. Regarding Harman U-shaped IEMs and hybrids, this particular model is definitely a well-executed example.
I believe it provides a warm and engaging tone that is enjoyable.

The KZ EDC Pro is packaged in a compact box containing the earphones, a standard cable, with the option to upgrade to a copper one, and the classic Starline tips. The EDC Pro has a mirrored faceplate and the clear, crystal-like resin body that looks fantastic, surpassing expectations for its price point. I have found both comfort and isolation to be on par with its competitors.

Sound:
The EDCX boasts a robust lower end, coupled with surprisingly controlled power. The Mid-Bass and Sub-Bass deliver impactful and swift responses, while the texture and details are outstanding, making it versatile for various music genres. The mids are clear and rich, endowed with a solid body; the lower mids are smooth and warm. Vocals, both male and female, are prominent and exhibit a natural timbre. The upper midrange frequencies are perceived as bright yet not abrasive. The highs are energetic and extended, detailed yet without excessive brightness that could lead to fatigue. The treble is well-controlled and safely tuned. The soundstage is expansive, with commendable width and depth, and the separation and overall accuracy exceed expectations.


Afterthoughts:
This makes an excellent choice for a daily driver; it's enjoyable, detailed, and free from harshness. Considering the cost, it would be an outstanding all-rounder.

Today, I'm examining the KZ AS10 Pro, the successor to the original AS10. The all-black packaging suggests a flagship product, although the accessories do not match up. Inside the box are the standard Starline tips and the usual cable that accompanies all their products. It's not a poor-quality cable; it's just unremarkable and lacks flair. The AS10 Pro earphones themselves look impressive and are well-constructed; however, they are on the larger side, so those with smaller ears should be aware that the fit may be tight. For me, I found them comfortable and snug, and the isolation was effective.

Sound-wise, the AS10 PRO represents a significant improvement over the original while preserving that classic tone.
Bass:
offers a satisfying depth that rivals many dynamic driver IEMs, with excellent extension, tight and controlled powerful impact, and impressive texturing. Both Mid and Sub Bass are remarkable, exhibiting an almost dynamic quality.
Midrange:
The midrange delivers a "smooth and natural" sound, with a lift that add thickness and warmth to male vocals, and presence to female vocals, without being overly harsh or fatiguing. The overall timbre leans slightly towards the warm and lush side. directly in opposition to the original.
Treble:
The high tones are smooth, yet they possess a natural detail, with a lift that imparts the perfect amount of sparkle and air to instruments, avoiding any excessive sibilance or harshness. They maintain a relaxed and secure quality with a well-managed upper treble extension.
Soundstage And Technical:
The soundstage is impressively spacious, offering an accurate imaging and instrument separation. Detail retrieval is just as impressive, with the drivers capable of revealing subtleties and textures across frequencies. The nuances in vocals and instruments are conveyed clearly, resulting in a more natural and life-like presentation.

Afterthoughts:
The new AS10 Pro is a capable and delightful IEM, with well-tuned BA drivers that are impressive, making it my favorite product from the brand to date.

The packaging of the new Penta P50 from 1More mirrors the classic style, featuring diagrams reminiscent of DaVinci's sketches, with everything presented elegantly. Inside, there is an extensive selection of ear tips and a pouch for the P50 Penta. It includes a small dongle for use with USB-C-only phones, and the cable comes with inline controls, which I found quite handy. Personally, I adore the design; my only wish would be for a case and higher-quality tips. The isolation and fit suited me well, and the build quality surpassed the unit's cost.

Sound
Bass:
The bass provides a deep and broad impact, with transient lows that will satisfy many listeners. The sub-bass has a gentle rumble but fades swiftly because of its rapid decay. The mid-bass is remarkable for its speed, marked by a swift decay that allows for a robust transient attack and efficient layering. The bass is well-controlled, textured, and exhibits excellent detail.

Midrange:
The mids are warm and lush with minimal recession, given the V-shaped performance. Both male and female present clear and finely bodied with a natural tone and good energy. Although there is noticeable bleed from the bass, it does not interfere and actually contributes to the richness and pleasantly thick tonality.

Treble:
The high level of detail is crucial here, owing to the P50's vibrant yet polished treble presentation. The top-end contributes an additional sense of clarity and "air" to the overall amazing and lively signature.

Sound:
The bass resonates broadly and openly, akin to standing before finely tuned monitors. The sub-bass is well-textured and controlled, exuding a refined smoothness. The mid-bass delivers a punchy yet lighter impact, characterized by its clear definition and quickness.
Mids:
The midrange delivers warm and full-bodied vocals; male voices sound rich and lush, while female vocals, though lighter, are equally captivating and natural. Both are a delight to the ear. The clarity is good, and the mids are warm and smooth. In general, I believe many will find this pleasant across all genres of music.

I3 MK3 packaging and build.
The packaging is vibrant and adorned with ample information, presenting a significant size difference compared to the original i3's simple black box. Within, one discovers three varieties of tips in multiple sizes to accommodate everyone ideally, included are also a cleaning cloth, a brush tool for cleaning, and a case.
The case is the standard yet high-quality KBear/TRI audio case, which is typically sufficient. However, considering the cable's remarkable thickness and sturdy build, I personally would have preferred a larger one. The I3 MK3 is constructed with high-quality aluminum, offering durability and a sleek design. The new i3 model is significantly more compact than its predecessor, ensuring a perfect fit in one's ears once the appropriate size tips are selected. The included cable is not only well-constructed but also looks fantastic in my opinion.

The equipment utilized for testing the i3 included the TRI TK-2 portable amplifier, The ifi Diablo-2, the Hifiman EF500 Amp/DAC, and various dongles such as the Questyle M15 and ifi GoBar Kensie, among others.


TRI i3 MK3 Sound:
Let's discuss the sound signature. It's worth mentioning that my musical tastes are quite diverse. Although rock, pop, and hip-hop dominate my daily playlist, I also enjoy country, jazz, contemporary, and world music whenever the mood strikes.
I'll begin from the ground up; I'm old school and have been in the game for a long time. I used to be a Stereo-Head, constantly upgrading my speakers and equipment, before diving into motorcycles and other interests. However, music has always been my motivation, sanctuary, and source of relaxation.

BASS:
The i3 MKIII is equipped with a 10mm Beryllium Dynamic Driver dedicated to its lower frequencies. These frequencies are expansive and dynamic, exhibiting superb control and energy. The Sub-Bass, in particular, delivers a commanding thump followed by a satisfying rumble before it fades, while the Mid-Bass boasts impressive speed and attack power.
This offers an enjoyable lower end with precision and quality, not a bass cannon or the typical overly V-shaped sound profile.

MIDRANGE:
The midrange on the i3 is exceptionally rich and smooth, with vocals displaying perfect tone and a natural-sounding timbre. The mids carry a substantial note weight and character, making them highly enjoyable to my ears.The clarity and layering, combined with a strong vocal position and smooth presentation, make the mids nearly perfect for most music genres.

TREBLE:
The MK3's highs are distinctive, featuring a 10mm planar driver dedicated to the treble frequencies—a rarity in hybrid IEMs, despite my experience testing thousands of them. The treble delivers a clean sound with excellent extension and airiness. It possesses a delightful amount of sparkle, and while the details are well-presented, the tuning leans towards a smoother and less sharp quality, resulting in a sound that is both natural and pleasing.

SOUNSTAGE ETC:
The soundstage of the NK3 is expansive and deep, offering substantial height and a broad field that extends slightly behind the ears. It boasts excellent imaging and placement, making it ideal for activities such as gaming and watching movies. In essence, it provides an open soundstage with impressive technicalities and high accuracy.

AFTERTHOUGHTS:
This is one of the best TRIbrids I've experienced this year, and possibly one of the best Hybrids as well. In its price range, I believe many will appreciate this very enjoyable and technically proficient IEM.

My thanks to HiFiGO for the sample https://hifigo.com/collections/kinera/products/kinera-celest-wyvern-abyss
https://hifigo.com/collections/kinera/products/kinera-celest-wyvern-abyss

As a reviewer who has tested and tried out nearly two thousand products, my opinions are shaped by experience and solely influenced by my passion for music.
My review is based exclusively on my experience using the Wyvern with the iFi GoBar Kensie, Hip-DAC 3, Gryphon, and several other DAPs, including the TempoTec V6. I listen to a wide range of music, focusing particularly on rock from the '90s and 2000s, as well as contemporary and metal genres.

The Wyvern Abyss comes in a simple yet elegant package that prominently displays the product. It's compact, and upon opening, one finds the IEMs already connected to the cable and tips. Unfortunately, it lacks a pouch or case. The build quality is robust, featuring a smooth resin construction that ensures comfort during extended use, and the isolation is excellent when paired with the correct size tips.

Specifications:
Driver Unit: 10mm LCP Diaphragm Dynamic Driver
Frequency Response: 20Hz-20kHz
Sensitivity: 105dB
Impedance: 16Ω
Connector: 0.78mm 2-Pin
Cable Length: 1.2m
Plug Type: 3.5mm

The Bass: is resonant and robust with the wide diameter ear-tips. I found the Sub-bass delivers a enjoyable deep rumble depending upon the Music. The medium speed of the impact leans towards the boomy side, there is surprisingly very little Bass bleed into the lower mids detected. When I listened to some Hip-Hop and Death Metal, the speed of the Sub and Mid Bass was more than adequate to keep up.

The midrange: is well-executed, providing a substantial body to the vocals. Both male and female voices sound full and robust, with the lower midrange offering a pleasant warmth and only a slight recession. The vocals are forward, positioned up to the center line. Overall, the midrange is rich and slightly dense, carrying good note weight.

The treble: extends nicely, offering a breath of air and a subtle sparkle, yet it retains a natural detail that avoids being harsh or sharp. It's a smooth, relaxed, and safe treble that carries just enough energy to keep it from being dull.

The soundstage: is wide and open, albeit with limited depth. Nonetheless, the technical aspects of the Celest Wyvern are above average, offering good separation details and accurate imaging without any congestion.

Conclusion: The Kinera Celest Wyvern Abyss might just be an exceptional value for someone looking for a fun and technically sound IEM. It looks fantastic and provides a good balance of bass and midrange, which is perfect for the rock listening experience I need.

Today, we'll be discussing the KZ Vader, an IEM featuring three 8mm dynamic drivers and a crossover. It includes four switches to customize its sound signature; although the changes are minimal, they are still perceptible. The Vader is packaged in the typical KZ box, accompanied by starline tips and the same silver cable that comes with nearly all of their IEMs, with few exceptions.

The Vader's shell boasts an attractive design, and its construction quality is above average for its price point.
Be aware that this particular model does not have the typically enjoyable KZ house sound that many appreciate, yet it still maintains a respectable quality in its own right.

Bass:
Starting with the lower end, the bass can be described as clean with an almost neutral tone presentation.

When listening to the Vader, the Mid-Bass is more pronounced, while the Sub-Bass remains in the background, offering a subdued rumble that quickly fades away. Overall, the bass is characterized by its precision, superb speed, and control.
Mids:
The midrange on the Vader is transparent and clean, offering a neutral presentation with fine details. There is clear clarity and separation between instruments, yet the vocals lack fullness, coming across as somewhat thin and forward. While male vocals sound adequate, a bit more body and warmth would be beneficial. Female vocals are slightly more pronounced and brighter but not excessively loud or harsh at normal volumes.
Treble:
The highs exhibit a bright and expansive extension, replete with fine details and a sparkling quality. The Vader's highs are energetically executed, displaying well-controlled and almost natural presentation of instruments and effects.

Soundstage ETC:
The soundstage is expansive, though with limited height and depth. It's accurate in placement, which is beneficial for gaming, and it remains intact during busy recordings, unlike some others.


Afterthoughts.
The KZ Vader marks a departure from their usual signature, and while die-hard fans may not appreciate the shift from V-shaped and fun tuning, I believe its unique signature is well-suited to EDM and similar genres of music. It's a neutral-bright IEM with impressive technicalities and details, especially considering its all-dynamic driver configuration.

The packaging is straightforward and informative, which is typical of KZ products. It contains the device, its charging case, and ear tips. It's unclear whether a charging cable is included; mine did not come with one, but it seems to be acceptable. The translucent smoke colored faceplate reveals the internals when exposed to light, which is a cool feature. The overall design is characteristic of KZ IEMs, offering a comfortable fit and excellent isolation.

Currently listening to the KZ Xtra, I'm enjoying the well-balanced bass that has a deep sub-bass rumble without being too dominant. The midrange is warm, showcasing a nicely projected vocal presence. The mids are richer and denser than average, providing a satisfying smoothness. The treble extends naturally and relaxedly, offering sufficient airiness and sparkle, yet it remains smooth and not overly lively. Personally, I would have preferred a bit more treble, but it functions adequately as is.

The ANC effectively cancels out daily life noises, and the call quality is crisp, perfectly suited for everyday tasks. Features like High-Performance mode and passthrough make the XTRA a great value and a convenient tool to carry on trips.

Bass: It delivers a solid Sub-Bass punch; although it's not the quickest, it has a satisfactory decay, and the rumble is less intrusive than others. The Mid-Bass isn't as pronounced but still noticeable.

Midrange: The Mids carry a substantial note weight, allowing for discernment of various instruments in their distinct spaces. They are rich and smooth, exuding warmth and a natural tonality.

Treble: The Treble is laid-back and smooth, with reasonable extension and a natural delivery. Given that this is a single-driver, wireless setup, it performs admirably.

When comparing products, the KZ Xtra distinguishes itself from the TinBuds 1. The TinBuds have a notably more pronounced lower end but do not match the clarity provided by the Xtra. Given their price point of only $55, they compete favorably even with higher-priced TWS options from brands like Beats, Apple, and Samsung.


In conclusion, the KZ XTRA provides a pleasurable listening experience without the necessity for wires, an external DAC, or a dongle. It's a convenient product with a delightful sound signature, making it ideal for workouts and walks.

The TinHiFi Tin-Buds-1 arrive in a simple yet robust box containing the earbuds, their charging case, a charging cable, and three sizes of ear tips. They sport a generic appearance with a tried-and-true design. The isolation and comfort I experienced were satisfactory. The call quality was decent, suitable for most environments, and the connection remained stable without signal loss up to 10 feet from the streaming source. The features are basic, lacking ANC or various modes, offering just a straightforward TWS earbud experience.

Sound:

In brief, the Tin Buds 1 deliver a playful, V-shaped sound profile with a pronounced lower end but little else. The mids are muddled and recessed, which is to be expected. The highs lack excitement, and the sub-bass is overshadowed by the significantly boosted mid-bass. While they are enjoyable, they don't compare to my KZ Xtra. Despite the 13mm drivers made from a composite PU+PEEK material, I anticipated a more balanced performance.

These are for the person who just wants a gym pair of earbuds that are fun I guess they are okay just not my cup of tea.

The unboxing offered a premium experience, complete with nicely arranged packaging, although it is exactly the same as everything in the NM / NA series.

Inside, the all-aluminum IEM shone beautifully, accompanied by a quality cable, two sets of ear tips in various sizes for Balanced and Bass types, an adapter, and a case that was aesthetically pleasing, albeit slightly small. The cable was well made and looks similar to the NM cable I have. In my opinion the best cable is from the NM2+

The comfort level was satisfactory, with decent isolation, although this might vary due to the short nozzles. The build quality significantly surpasses its price point.

Sound impressions:

Bass: It offers a balanced profile with a more pronounced Sub-Bass than Mids. The bass sounds natural, is of high quality, clean, and provides a respectable punch characterized by clarity and fine details. The bass is controlled and well-textured.

Mids: They are clear and well-defined, with an emphasis on the upper Mids and almost neutral lower Mids. The details are impressive, offering transparency that I found refreshing and enjoyable on most recordings, despite a few hot spots that did not significantly diminish my enjoyment. Both male and female vocals sounded natural, possessing a robust body and vibrant energy.

Treble: The treble is open and detailed, the sound is devoid of sibilance, featuring well-managed highs and a moderate level of sparkle. There is a nice natural tone to the treble and less heat than the NM2+ in the lower treble.

Soundstage: The soundstage is wide and natural, tapering off into the distance appropriately, with a slight, almost 3D effect. Excellent imaging and separation contribute to an outstanding overall presentation.

Conclusion: This IEM is exceptionally well-crafted and fits comfortably. It is highly detailed and surprisingly enjoyable, even if the mids can be a bit intense at times. Designed for monitoring, it is likely one of the most affordable options in its category. It should appeal to those engaged in professional and critical listening rather than those seeking a casual listening experience with pop music. Hit or miss? I appreciate it for its qualities and find it refreshingly pleasant.

The RG15 fully leverages the Assassin's Creed brand to influence its design. The gold finish, patterns, and insignia are aesthetically appealing and thematically consistent with the setting of Mirage. It stands out in its price range, and this high quality extends to its fit. Despite the luxurious design, the physical shell is quite compact, making it comfortable for extended wear, although the weight may cause a slight tilt without properly sized ear tips.

The RG15 is equipped with a Type-C plug featuring built-in DSP tuning. It utilizes 5N oxygen-free copper wire for superior sound transmission quality. Crafted to enhance your gaming experience, it allows every note and sound effect to provide an enhanced experience when gaming.

The Bass on the RG15 is notably subdued. Unlike other gaming IEMs, you won't experience a bass response rich in texture and body, which may be disappointing. Nevertheless, the bass maintains a notable presence in the mix, subtly enhancing the sound signature. Specific sub-bass frequencies provide a robust foundation for effects. Although it seems quite distinct from the overall sound signature, this clear distinction may be advantageous for gaming. The RG15 still delivers an enjoyable rumble, albeit not as thick as one might expect from gaming earbuds.

Midrange:
The mids on the RG15 are exceptionally transparent, forward, and clear. The effects are detailed, and the separation is well-executed. The vocals are not excessively thin and possess a pleasing timbre. This provides a clear sense of the origins of footsteps and dialogue. However, the mid-treble is less stable, exhibiting some spiciness in some vocals.

The Treble:
The highs on the RG15 possess a considerable amount of sparkle and airiness, delivering very good detail. The effects, such as metal clashing against metal and the overall atmosphere, are presented naturally and effectively.

Soundstage: It is open, offering expansive detail with impressive depth and height. The layering is superb, and the imaging is precise, making it well-suited for gaming.


This IEM is well-crafted, whether for gaming or music listening, its capabilities are impressive. The onboard DSP and DAC make it very convenient for traveling and mobile gaming. I personally appreciate its design, and it performs admirably for RPG games and occasional music sessions.

The Truthear GATE is an affordable IEM that serves as a successor to the previously sold HOLA in their product lineup.
The Gate arrives in a simple box adorned with attractive artwork on the front. Inside, you'll find the Gate, the same cable as the Hola, two types of tips each with a different size bore, available in various sizes, and a pouch. I found the lightweight build of the gate to be comfortable using the medium tips, I experimented with wide and narrow boar tips finding I liked the latter of the bunch. While the transparent faceplate might not be traditionally attractive, I believe it has a certain cool appeal. Considering the cost, the build is decent, and at normal volumes, the isolation is found to be above average.

I evaluated the GATE across a wide range of devices, focusing on portable ones as they would serve well as travel IEM or a good spare. The equipment utilized comprised the Tempotec V6, Hidizs XO, Thruthear Shio, ifi Hip-Dac 3, and Fosi SK02.

My impressions of the sound:

Bass: I found the Bass to be lighter than the Hola, yet it still delivers a very good bass with control, excellent detail, and texture. The Mid-Bass delivers a quick impact, while the Sub-Bass provides a substantial rumble.

Midrange: The midrange delivers outstanding clarity and a nearly neutral performance, with a slight warmth in the lower mids and a subtle brightness in the upper midrange. The vocals possess a transparent quality and, although thinner than the Hola, they maintain a substantial presence in the notes with a pronounced forward position.

Treble: The highs are relaxed and not at all harsh, which makes the upper brightness of the mids less fatiguing and more enjoyable. The treble extends well and is reasonably detailed, although it lacks the energy I would prefer.

Soundstage and technicalities: It is noteworthy that the GATE features a wide yet not as deep stage. Nonetheless, it boasts commendable separation and detail, with imaging that is notably above average in terms of accuracy.

My final thoughts on the New Truthear GATE:

The Gate provides an excellent mix of technical prowess and enjoyment for under $20. With the inclusion of a pouch and cable, it represents great value and would serve well as a beginner IEM or as a spare for travel. Given its sound quality and comfort, it's difficult to find fault at this price point.

Here is my thoughts on this Tangzu X HBB Xuan NV

The Shell is a nice all resin design it is both attractive and comfortable with good isolation for me and they are light.
The tips are unique, and I must say I like them. The cable is not bad quality per say but is a very sticky kind of rubber that catches easily on my clothes and attracts lint, hairs, ETC. it comes with a kind of case pouch thingy like some of the Truethears.


The Xuan NV Sound:

It presents with a neutral-warm signature.
Bass: is punchy and Sub-Bass has a nice rumble and decay. Mid-Bass punches quickly and both are well tectured with excellent control.
Midrange: Mids offer a thick lush presentation with good vocals particularly male but that's not to say female dont sound good as well. vocals have a good potion and clarity this IEM in my opinion leans more towards a U shape tuning.
Treble: The highs offer an almost totally Neutral presentation with good sparkle and air but zero harshness. The highs are smooth and safely tuned so even treble sensitive should find them well tuned. Details are average and the smooth non fatiguing highs are not for treble heads.

Soundstage: The stage is accurate with good placement but less deep than it is wide. While not a technical wounder it does do a decent job for a dual dynamic IEM.

In a nutshell: The neutral-warm signature and relaxing nature of the Xuan NV make a perfect all-around everyday IEM for me I love the enjoyable and fun tone.

The Kiwi Ears x Crinacle Singolo is another collaboration from Crinacle with his signature sound and an interesting innovative technology the (Kiwi Acoustic Resonance System).
The Medical grade resin is comfortable and despite the short nozzles I found the isolation good as well as the fit. The Singolo comes with the units, a cable and some tips. accessories are sparce and the silver-plated cable is just fine but nothing special. It does have those odd 7Hz style curved horn shaped two pin connectors. The Singolo has a 11mm custom LCP dynamic driver that was made in Japan for them.





Here are my impressions of the Kiwi ears Singolo:

Bass: is the subject of focus here. The 11mm driver and Helmholtz resonator give a clean and deep Bass response with Sub-Bass front and center with good depth and a healthy rumble, Bass in general is well textured and Mid-Bass has a speedy and notable impact but is not the most accurate.

Midrange: While not the most technical the Mids do have a natural tonality and present almost Neutral. There is a little recession in the lower Mids and a mild warmth, upper mids are transparent and neutral for the most part. body and vocal energy are above average.

Treble: The Highs are relaxed with a decent but lackluster amount of energy and sparkle, there is enough air and details but ultimately it is a smooth and relaxed extension.

Soundstage: Is decently Wide with less depth and good imaging and separation. this is not a technical IEM but it does good enough here.

Equipment Used:
I use a large variety of devices but mostly I used the Fosi SK02, Burson Funk, Tempotech V6, Pixel 8 pro, Pixel 7, the Questyle M15, ifi GoBar, Diablo-2 and Gryphon for most of this.

My final thoughts:
I like the enjoyable signature of the Singolo for Jazz and K-pop music, not that it didn't work on rock and Pop, but I think there are others in the price range that do a better job. that said the Bass is fantastic on these. I think they would be a good travel companion.
