Let's start with the.

The boxing experience was fantastic, with numerous accessories included, even compared to my much more expensive Moondrop Variations. The packaging appears premium, and the organization of items in smaller boxes led me to believe this was an expensive set. Well, done, Simgot!
The inclusion of four nozzles allows for significant tuning to your preference, and the standard nozzle bore enables the use of nozzles other sets and manufacturers.
The ET142 is built solid and best many other sets of higher cost with ease. It has a very thick and beautiful cable made from OFC and silver plated OFC lits. It is also modular making it compatible with all my devises and I really appreciate that feature.
The 142 also comes with 3 styles of tips unfortunately none are foam for those that use them.
You also get 4 tuning nozzles 2 are longer and there are replacement filters and rings also included adding to the longevity of this set. We round off the acessories with a nice case similar to the one with the EA1000.
As for isolation it was perfect with the medium nozzles. Fit for me was tight but comfortable, I fear smaller ears might have some difficulty because these are larger than average.
Equipment used:
Fossi audio SK02 and SK01, ifi Gryphon, TempoTec V6, Periodic audio Neon BT, Creative Soundblaster G8 and Fiio KA13
High quality MP3, DSD , FLAC + ALAC, and some streaming in LDAC.

My sound impressions after burn-in.

The Simgot ET142 was a joy to listen to right out of the box. I heard it needed burn-in, so even though I don't believe in such things, I did it for the sake of others.

We start with the lower end of the 142, the Bass was super controlled with excellent details and texture but is far from Bass head territory. The Sub-Bass carries the tones with that typical "PLANAR" Bass. The Bass line is neat and clean with good transient and depth but could use a little more emphasis, nothing that can't be resolved with Xbass if I really was in the need for it. That said, the Mid Bass is slightly behind the Sub but it's not lacking in texture quality and speed. There is enough Bass here for any type of music, double Bass drums sound fantastic. The overall bass analysis reveals a well-defined punch, adequate depth, speed, and quality befitting of a planar IEM.

The Midrange and vocals are greatly affected by the nozzles, ranging from a brighter and thinner response to a rich and meaty one. The ability to customize the mids are highly appreciated as it's like having a variety of IEM in one package.
Mids are focused and clear while with one nozzle there is a warmer signature this is not a set for the warm rich Harman found in other sets yet there is enough to be pleasing to my ears. Planar timbre is present but is not impeding my enjoyability as I like most planar sets. Vocals have good wight with the red ringed short nozzle but are always energetic and the titanium nozzle was overall enjoyable while I didn't care for the gold one as I thought it was too much. This is subjective and everyone hears differently. Midrange in general are clear and detailed with good energy and air, separation is far above average, and I would classify the 142 as a mid-centered IEM.

Treble can present as very airy and a nice upper limit with fine details and ample energy. Treble enthusiasts may prefer gold or titanium depending on their preference. I found the Titanium nozzle to be more my tastes when it came to upper tonality. Treble in general is open and spacious with clarity befitting of a flagship IEM, I could find no fault with how everything sounded listening to my eclectic collection of music.

Soundstage: Perfectly suited for the 142 the soundstage is wide and has a decent depth even if lesser than the width. Details are perfectly placed and not affected by congestion like some other IEM. Compared to the MoonDrop Variations I am testing out it is more detailed but far less holographic. I think both would work for gaming but perhaps the Better Bass and holographic stage would make the Variations a little better.


In My opinion the Simgot ET142 is a versatile IEM with a very quality lower end an excellent Midrange performance and upper treble of superb clarity, with class leading technical performance and while the 142 needs to be tuned towards your preference it should be decent for most people "after burn in" I can understand some of the points of negative but with the right , nozzle, filter, and tips these can be amazing!

The AGASound AGA ONE is a nicely built IEM with a 3D printed body and a metal faceplate. It looks sleek and modern. I found them very comfortable, and they provided above average isolation. The cable was actualy good as stock cables go, I found it both good looking and sturdy. the tips included were okay and provided a good fit for me.

Inside the box you will find the following
Aga OneIEM

Lets get into the sound:
The AGA One Has very good quality Bass while not exactly Bass head it still has a nice Sub-Bass presence and enough depth and width to be quite enjoyable on recordings that are more Bass oriented. Mid-Bass is no slouch it too is well refined with good control and speed.
The Mids are very interesting with the vocals being centered and not pushed forward, they are far from the typical Vshaped recession but instruments in general are slightly in front of them. The Mids have good clarity and note weight is also good with above average separation and are more towards a smooth rich Midrange with decent technicals.
The treble is well controlled offering enough energy and air without overextending or harshness. The soundstage is fairly wide with less depth and height, but good imaging and it doesn't fall apart on bad recordings.

In a nutshell:
The AGA One is a under $40 IEM with good build quality and a pleasant smooth Harman tuning for a comfortable and relaxed listening session anywhere. I like the look and find it very enjoyable as an everyday use IEM.

I found the KA13 to be a well-built Dongle with a nice modern look and cool lighting on the window. It sounds very neutral and has good details and a healthy amount of power 550mW, this means it can power full sized headphones as well as sensitive IEM with a low noise floor. As a Dongle it very much improves the sound quality and volume but it should be noted this is not the most dynamic sounding dongle. Note wight is thinner and highs are on the sharper side as it is very detailed and analytical depending on the IEM or headphones used this may be less.

I tested out the KA13 with the Meze 99 classic, HifiMan Sundara the MX Ray MF1 headphones and the Dunu DK3001bd, ROSESELSA Star City pro 5 and Westone Mach70 IEM

The Hidizs ST02 Nebula is a Single Dynamic driver IEM with a built in USB-C DSP Dac cable, this allows you to grab it and go without the need for other equipment. the cable can be switched so you can use it with your favorite dongle or portable player.

Inside the box is the IEM, a small pouch and the cable, a USB-C-to-A adapter and tips. The ST02 is lightweight and comfortable it is made of mostly plastic and has coin like faceplates. The cable is sturdy enough, but some may not like the nylon construction as it can tangle and kink.

Sound wise the DSP is tuned to give a bright Harman response with mild Sub-Bass impact and more focus on the Mid-Bass is typical Harman tuning with Sub-Bass rolling off fast and only a mild rumble when listening to boosted music. Mid-Bass hits fast and is very well controlled with nice texture.
Mids are mildly recessed with vocals being a little thicker than I was expecting, still everything sound as it should be, and nothing is out of sorts.
Treble is well extended with a nice natural tone, it is not the most detailed but has a nice smooth presentation that most will like.
Soundstage is wise with decent depth but nothing holographic are large, these are decently accurate but I wouldn't use them for gaming.

In a nutshell: The ST02 Nebula is good considering the cost and has potential, the selling point here is it's good to travel with for convenience and it has a enjoyable signature.

The unboxing experience of the Dunu DK3001BD is top-notch and among the most memorable I've had. It comes with everything shown above. The modular Cable is super sturdy, the case so spacious and a nice assortment of tips are also included.

The lower frequencies of the Brain Dance are expansive yet lean towards a balanced and controlled character. The Sub-Bass is responsive and capable of a robust rumble on enhanced recordings when necessary, while the Mid Bass is more subdued and precise, yielding prominence to the Sub-Bass. It's unexpectedly effective across various music genres. Bass enthusiasts may not favor it, but its long-term listenability appealed to me. The lower frequencies are best described as well-textured and intricately detailed.

The midrange of the DK3001BD possesses a pleasant, natural lightness, neither too thick nor too thin, providing just the right amount of body to feel appropriate. The vocals are placed forward, and while they lack the thick and rich character I'm accustomed to, they still sound correct and appropriate to me, with a natural timbre and placement. Great separation and clarity round off these natural and balanced Mids.

The treble extends well, offering good energy and an airy, detailed presentation. The highs have a sparkle and openness without crossing into the harsh, brighter peaks that some IEMs exhibit.

The soundstage of the DK3001BD is superb, offering a well-rounded experience with ample height and depth that complements its wide and open staging. The placement and accuracy are precise, ensuring no issues even with busy recordings.

In a nutshell:
The Dunu DK3001BD is an exceptional mid-tier IEM known for its respectable technical capabilities, detailed sound, and overall wonderful audio experience. Its aesthetic is also noteworthy; however, the larger shell size is something to consider.

The build quality is excellent, which is what I've come to expect from Cleer Audio. Included inside the environmentally-friendly packaging are the charging dock, a cable, and the units. I found them comfortable except when wearing big sunglasses.

Sound-wise, the ARC has evolved based on customer feedback, offering an immersive audio experience while preserving the openness of the ARC-3. The bass is significantly enhanced, delivering one of the best impacts for earphones of this kind. The clear midrange and sparkling treble are pleasing to the ears. Its balanced sound signature leans towards the brighter side, providing good detail for such a device. Additionally, the Dolby feature performs excellently for watching videos and gaming on the go.

The Capsule 3 Pro is well-crafted, boasting impressive internals and features. Similar to the Pro Plus, it supports LDAC, which I appreciate greatly as it enhances my streaming experience.
It comes in various colorways and i picked the see through as it was nostalgic looking.

In terms of sound, the Capsule 3 Pro closely resembles the Pro Plus in its lower-end capabilities, yet offers a more balanced and robust midrange, as well as an even treble, thanks to its single 12mm dynamic driver. The ANC functions flawlessly; I used it on the bus and could completely immerse myself in my personal music world. The call quality was clear and flawless with no cut outs or lag. I discovered that the C3 Pro offers a nicely balanced bass with good texture and punch, a rich midrange with a decent body, and only a slight recession in vocals on certain recordings. The treble sounded crisp and clear with natural details. The soundstage was precise and wide, providing enough space for gaming.

In a nutshell
The Soundpeats Capsule3 Pro is yet another impressive offering from the company, delivering high quality and features at a reasonable price. It boasts a pleasant sound profile that doesn't cause fatigue, along with excellent active noise cancellation and call quality.

A simple box, a straightforward design, and starline tips paired with a non-detachable cable characterize this lower-budget IEM. KZ Dawn presents two premium cable choices: silver-plated and OFC (Oxygen-Free Copper), each tailored for distinct audiophile preferences. The silver-plated cable, crafted from a 0.06mm high-purity oxygen-free copper wire core, delivers enhanced conductivity for a cleaner, quicker signal transfer, which amplifies the clarity and luminosity of each note. On the other hand, the OFC cable provides a harmonious, balanced audio performance, delving into the music's core with a deeper, more resonant texture. I found its lightweight and a see through looks to feel cheap and uninspired but comfortable.

The sound impressions offer a pleasantly warm, V-shaped IEM experience with a solid bass punch and warm mids that, while slightly recessed, deliver a rich and full-bodied presentation. The treble response is less relaxed, providing a nice sparkle and breathability.
This makes a great additional or backup set if you enjoy an IEM with a fun, warm sound profile.

The CVJ Aria stands out as a unique IEM despite its common name. Within the unassuming packaging lies a stunning illustration of a surreal world. It includes two types of tips in various sizes and a compact round metal case, which I initially thought was too small. The Aria also comes with tuning nozzles, with the blue one being my preferred choice. The included cable is quite impressive and ranks as one of my top stock cables; I would definitely rate the cable alone a 4.9 out of five. The comfort and isolation are as good as the build quality, all of which are excellent.
Specifications

Model : CVJ ARIA
Sensitivity : 110dB

Regarding the sound, I will only mention the silver and brass nozzles once because I find them unsatisfactory; however, you can enhance your experience by using nozzles from other brands. The silver nozzles amplify the highs to an extent that I perceive as harsh, while the brass nozzles muffle the sound, and despite a more V-shaped profile, they fail to capture finer details.

Blue Nozzle.
With the Blue nozzle, the Aria presents a balanced sound profile, boasting detailed lows and improved texture. While the bass may seem light on certain tracks, pairing it with a warm source like the Hip-dac3 or Burson Funk significantly enhances the experience. It may not satisfy bass enthusiasts, but it performs adequately, with balanced sub-bass and a mid-bass leaning towards neutral, characterized by a quick attack and decay.

The midrange, in its stock configuration, is neatly executed, providing just enough energy to satisfy and detailed enough to be clean and clear. It has a brighter upper range but is thinner compared to others in its price category.
Treble is clear and bright with good air and sparkle but very well controlled and detailed at normal volume.
The soundstage is excellently done, offering a broad and expansive presentation, albeit with a bit less depth. Imaging is precise and reliable across various recordings, with movies and games remaining clear and uncluttered.

In a nutshell
The CVJ Aria is a finely crafted IEM made from aircraft-grade aluminum, featuring excellent accessories and a distinctive, fun, bright, neutral/balanced sound signature that varies with the nozzle used.

I would like to express my gratitude to Apos Audio for providing the IEM. As always, my opinion is solely my own, and I have not been paid or coerced in any way.

• Impedance: 80Ω ±15%
• Total Harmonic Distortion (THD): <0.05%
• Cable: 4.92ft (1.5m) OFC braided cable
• Connector: 0.78mm 2-pin

We'll begin with the box; it's a decent-sized, blue and black box with comprehensive information about the item on the outside.
The box contains the Hane IEM, a beautifully designed faceplate with a blue, sparkly, feather-like design, well-crafted from medical-grade resin. It comprises a vast array of tips of various kinds, a decent yet slender cable, and an extremely small pouch.

Sound-wise, the Hane offers versatile directions; it's just north of balanced with an almost neutral tuning by default, and with a single switch, it can boost the bass to highly enjoyable levels, or further switches can fine-tune or amplify the treble.

In its default setting, the bass is quick and has a pleasant, subtle rumble, as I discovered while listening to LL Cool J's "Murdergram." With the first switch engaged, the bass gains a bit more depth and the rumble intensifies, which I find to be the best setting, especially when listening to Teddy Swims' "The Door." The bass can be subtly textured with decent detail or more pronounced with a slight decibel increase using the first two switches. The midrange is clear and perfectly neutral, with a touch of brightness at the upper end on the default setting, which shouldn't be a problem at normal volume. The Treble offers a clear and sparkling sound quality; it is not overly sharp but can be adjusted with the final few switches.
A soundstage that is well-rounded, offering good imaging and details within an open and equal field.

In a nutshell
The Hane Arpegear is a nice-looking IEM with good isolation and fit, it has a tunable neutral sound with the ability to increase air and treble as well as bass. the switches actually work well on this one and while the cable is thin it is robust, and the pouch is probably my least favorite thing.

Kima and Kima 2


Impressions:
The Dunu Kima 2 arrives in an attractively designed box featuring impressive graphics and includes an extensive array of accessories such as a large case, four different types of ear tips, and a high-quality cable, reminiscent of the Titans. I found the build to be exception with its all-metal shell and large number of tips to choose from. isolation was good for me with the stock tips. I would have preferred the green, but they look good in silver and don't attract any fingerprints.

Transparency:
I would like to express my gratitude to Dunu for sending the items to me. As always, I appreciate the gesture. However, possessing a substantial collection, it does not influence my opinion since I do not require them and I donate all my surplus IEMs to charity.

Equipment used:
I used mostly the Anue Yuki, IFI GoBar Kensei, ifi ZenDac-3, Hifiman EF500 , ifi Diablo-2, Gryphon, and HipDac3, Mamoritai Audio Euphony and from TempoTec V6 , Pixle-8 pro running android 15 as well as windows 11 desktop. The files ranged from HD-streaming to DSD.

Sound:

Let's delve into the sound of the Kima 2; the lower frequencies, especially the Sub-Bass, are focused and finely tuned, leaning towards a slight elevation above neutral. The bass has a pleasant rumble and texture, yet it is not overly bass-heavy, making it suitable for those who are not bass enthusiasts.
The mid-bass added sufficient warmth to the lower midrange, enriching and tastefully coloring the tones. The mids are well-focused, with a pleasant thickness and note weight that contribute to the enjoyment of this Kima.
The upper mids and treble are sufficiently open and possess a pleasing level of clarity, presenting both smoothly and without harshness.
The soundstage of the Kima 2 is sufficiently wide, though lacking in depth, yet it offers good imaging and separation. In most cases, it performs well enough for media and gaming experiences.

In a nutshell.
The new Kima2 represents not just an improvement, but also a slight shift in direction. It offers a pleasant and enjoyable experience throughout the day, complete with exceptional accessories and build quality.

Video:

Let's begin with the items inside the robust and informative box. Within, one will find the charging case, the earpieces, the charging cable and tips, as well as a manual.

The i5 boasts numerous features such as a 12mm topological diaphragm, a HiFi DSP chip with master-tuned EQ, and 48dB noise cancellation within a 4000Hz frequency range, achieving up to 98% reduction of daily noise. It also includes GoerTek microphones for HD clear calls, the capability for dual device connection, and a game mode that ensures 54ms low latency performance. The i5 supports features like LDAC, LLR lightning latency and ELC Equal loudness contour.

The design is quite comfortable, and the oval tips are expected to fit seamlessly with the provided tips. passive isolation is very good. The touch controls are somewhat complex, yet it's convenient to have all the features readily accessible at one's fingertips.
Sound;
The Earfree i5 boasts a well-balanced stock signature that is universally appealing, avoiding any fatiguing or harshness.

The bass delivers a solid punch that doesn't encroach on the midrange, while the treble is crisp and detailed, offering a pleasantly natural extension. The soundstage is impressively wide, enhancing the experience for mobile gaming on phones or the Nintendo Switch.

In a nutshell:
The Earfree i5 is a well-crafted and stylish TWS with competent ANC, calling capabilities, and a great universal sound profile.

The Clavelon Delta is certainly a unique IEM, boasting a cool-looking box and an unusually designed shell that may appeal to many.
The build is superb with a
Ergonomically Enhanced Design for Supreme Comfort,
Cyberpunk-Inspired Triangular Geometric Aesthetic,
High-Fidelity Audio with Precision Tuning,
CNC Precision-Machined Aerospace-Grade Aluminum Alloy Shell,
Custom High Magnetic Titanium Dynamic Driver,
Premium Hybrid Cable with German-Imported OFC Copper and Silver-Plated Copper,
Specially Designed Acoustic Eartips for Superior Sound Isolation.



Acoustically, the Delta is quite fascinating; it has a significant sub-bass depth that belies what the graph may suggest. The custom-designed high magnetic titanium dynamic driver delivers exceptional clarity and control to the lower frequencies, with the mid-bass slightly less dominant than the sub-bass.
There is a slight bleed into the midrange, which provides the lower frequencies with a pleasant warmth and gives vocals sufficient body and thickness to be highly enjoyable, all while preserving balance and exceptional resolution.
The treble is excellently managed, exhibiting only a minor enhancement in the upper treble that wasn't noticeable until the volume was increased. Nevertheless, the treble remains open and airy, free from any harshness or fatigue.
The soundstage is wider than average but lacks depth and height, although it does offer excellent imaging and detail.

In a nutshell
The Delta stands out as an exceptional IEM; though not without flaws, it offers considerable technical prowess and resolution for the budget-conscious audiophile market.

The packaging exudes the typical budget IEM aesthetic found with brands like KZ or the more affordably priced offerings from KBEAR. Inside, there are some tips and a slender cable. The DC02 is available with or without a microphone and comes in either black or silver. The comfort level of the SOLO is superb, offering good isolation, and the silicon-made CCZ fin on the back is great. The IEM fits well into the ear and is well-crafted.

Sound:
The lower end of the Solo DC02 is enhanced, offering a quick and deep bass response with fine texture and control, without overshadowing the other frequencies. The mid-bass hits well, but I believe the sub-bass is slightly more dominant. Listening to "Laid to Rest" by Lamb of God is one of my test songs; the bass kept up nicely and was enjoyable.

The midrange is crisp, exhibiting slight warmth and fullness in the lower mids, while the upper mids are bright and distinct. Vocals are well-balanced, with placement that is neither too forward nor too recessed.

The high frequencies offer a pleasant amount of sparkle, leaning more towards a balanced and safe profile, yet they still deliver a natural and clear sound.
The soundstage is impressive, providing a broad and open sound with excellent imaging and detail. While it may not be the best, it is outstanding for its price range.

In a nutshell:
The CCZ Solo DC02 is a reliable and outstanding IEM for its price, offering both solid technical performance and enjoyable, yet safe tuning.

Starting with the basics, the packaging remains consistent with what I've tested since the ZST Pro many years ago. The cable has significantly improved from the original striped, bendable ear hook design; it may not be the most aesthetically pleasing, but it's durable and built to last. The tips have remained unchanged, with their foam tips being particularly good, and the reliable star-line tips providing an enhanced bass experience due to the narrow opening, making them suitable for everyday listening.
KZ has made certain claims previously, but I focus on reviews, not politics. I've experienced high-end IEMs and personally own several in the $500-$1500 range. My reviews cover what's accessible. Surprisingly, I've encountered $20-$100 IEMs that deliver excellent sound quality. Conversely, I've been let down by $400 IEMs.

Sound ;
The sub-bass rumbles forward with robust intensity and depth. Its texture resembles that of a typical planar driver, characterized by good speed and decay. The mid-bass, while commendable, is slightly subdued in intensity and impact compared to the sub-bass, making it less prominent.
The midrange integrates seamlessly into the mix, offering a pleasant touch of lower warmth and a crisp, nearly neutral upper midrange. Vocals are well-positioned, neither overly thick nor artificially brightened, but clear and subtly detailed, exhibiting a characteristic planar timbre.
The treble on the PRX extends well, offering a controlled energy level with ample airiness and detail. The highs are less amplified yet still provide a pleasant sparkle, avoiding the overly harsh spikes previously experienced.
The soundstage on the PRX is of medium size, with its depth and height being approximately equal, and the placement and separation of sounds being notably above average.

In a nutshell;
The KZ PRX represents the ongoing evolution of the KZ planar series, with each iteration improving in various aspects. Regardless of personal preference, KZ boasts one of the most extensive collections of budget IEMs known for their solid construction and diverse tuning options.

The packaging remains the classic KZ style we've seen over the years, now with star-line tips and, interestingly, a copper cable—a notable change.

Straight from the start, the Saga emphasizes bass, as expected from its Bass version. The bass delivers impressive speed and impact. When listening to "Arlandria" by Foo Fighters, one of my favorites, the mid-bass power and speed are quite impressive. Transitioning to LL Cool J's "Murdergram," the sub-bass comes through powerfully, with a deep rumble that strikes hard and fades at just the right pace. Even though the bass may be slightly less tight compared to the Castor, it retains sufficient control, texture, and depth to be satisfying.
The midrange, contrary to expectations, is not as warm and thick, yet it retains sufficient body and note weight, with a hint of lower warmth. The upper midrange register presents almost neutrally. Vocals are slightly recessed but remain well-centered and in front of the instruments.
The treble tones are mellow, and although slightly subdued, they sound authentic and possess sufficient breathiness to be pleasurable. I would describe it as having a pleasantly smooth treble that provides ample detail.
The soundstage of the Saga isn't exceptionally broad, yet it offers reasonable imaging with precise details and placement.
The KZ Saga is another cost-effective, fun, and well-tuned IEM for casual enjoyment of pop and rock music. I appreciate its enjoyable signature, although it is in a market saturated with others.

The TempoTec Sonata BHD DSD is the company's latest Dongle-DAC, featuring physical volume and gain buttons.
The device comes in a simple box with the unit and a short, braided silver cable. The build is both metal and a glass like material.

Let's begin with the sound quality of the BSD; it boasts a warm, analog tone with ultra-low noise and substantial power output. This isn't to imply that the details are grainy; rather, they possess a pleasant, rounded, and smooth presentation. The BHD delivers a dynamic sound with a rich midrange and sufficient airiness in the upper registers. The soundstage is reasonable and offers good placement.
The brass side button adjusts the gain, and the Sonta features three levels of gain indicated by the front ring LED: yellow for low gain, purple for medium gain, and cyan for high gain.
The BHD supports files up to 32Bit/384kHz and also decodes DSD codecs up to DSD 256. It also has a single ended 3.5mm and a full Balanced output with a 4.4mm.
The TempoTec provided ample power for most in-ear monitors (IEMs) and several low-impedance headphones. It delivered excellent performance with the Aune AR5000 headphones and the Meze 99 Classics. Additionally, it was tested with demanding IEMs such as the 1More Penta P50, as well as planar models including the SuperMix4, MP145, TRI i3 MK3, and Audeze LCDi4, managing all with sufficient volume and without any distortion.

I used it on both my Pixel pro phone, Samsung Galaxy as well as my iPad and various DAP like the V6 from TempoTec.

The Tempotec sonata BHD DSD is a good looking and rich sounding Dongle with ample power.

The packaging is attractively simple and well-documented. Inside, you'll find the S08 and the standard plastic case. However, I have a preference for the older Letshuoer cases. I found the unique looking shell to be adequately comfortable, build is solid with an all-metal build. It come with different size tips in two types. The cable is very attractive and being modular is a feature I appreciate greatly.

Sound:
The bass hits with significant impact and satisfactory speed. It boasts a broad and profound sound, akin to experiencing a full-range speaker complemented by a subwoofer in the background, delivering the music with vigor.
The sub-bass maintains a fair amount of control while delivering a pleasant rumble; the bass in general has good detail and texture.
The midrange is robust and rich, offering a natural warmth and tone, though it may be mildly recessed depending on the music. There are still decent details, but overall, this is not a technical IEM; it's full and enjoyable.
Treble is decently extended with fair amount of air and sparkle, but its presentation is rather smooth and laidback for the most part it is fine.
The soundstage offers average imaging but lacks an open and expansive field; it is relatively small and can become congested with complex recordings.

In a nutshell:
The S08 remains an enjoyable planar that requires power to reach a decent and pleasurable level. It's not suitable for all music genres and definitely not ideal for gaming. It's simply enjoyable—take that for what it's worth. In my view, the S15 and S12 Pro are significantly better.



Video Soon!

Let's start with NF audio, a company that has been around and makes some great IEM for both professional and the everyday listener. Now known as NF-ACOUS. The packaging is that same wonderful CD style box I like opening. inside is tips of various sizes and a new type of square case as opposed to the traditional round one. A new logo in similar font to metal band judas priest is on the front with a N.

In a nutshell:
The NM20 IEM feature a finely tuned mature V-shaped sound signature, a stunning design, and a high-quality but lightweight feel. They boast an impressive technical and fun sound, with a wide soundstage that has superb imaging for the price. The soundstage is expansive, the sound resolution is high, and the details are crisp. The bass is robust, offering great value for money, all complemented by the robust and attractive packaging we are accustomed to from NF.

Sound:
The bass boasts impressive depth and a warm, well-textured slam, yet it is not over-boosted to the bass-head levels typical of V-shaped IEMs in this price range. Instead, it offers a well-defined and controlled bass, with both sub-bass and mid-bass being detailed and possessing a very fast attack. The bass may not be at 'bass head' levels, but I believe many will appreciate its quality and quantity.
The midrange delivers flawlessly, offering a subtle warmth and a gentle dip in the lower frequencies, complemented by a brighter, more vibrant upper range that maintains clarity. Vocals naturally position themselves just slightly ahead of the instruments. The mids themselves have good separation and details are impressive.
The treble is impressively extended, offering a good amount of air and sparkle, especially for a single driver. Those sensitive to treble may find it energetic, particularly at higher volumes and on brighter equipment, but I found it to be just fine and appreciated the openness.
The soundstage is expansive, as wide as it is deep, offering spot-on imaging with excellent detail placement that doesn't suffer from busy recordings at all. This would make it an excellent choice for gaming.
