TL;DR
Who should consider the Letshuoer EJ07?
• Those who would want a safe tuning and is good in almost any track except for orchestral or instruments that needs details.
• Those who loves imaging and soundstage.
• Those who listen to Pop or EDM tracks will sound great in this IEM as it mitigates the bright sound nature of those genres.

Tonality (6/10)

The EJ07 offers a fair tonality with a neutral to warm sound signature. Which offers tracks with a non-fatiguing and a more relaxed listening experience. Upon first listen, what stands out is the IEM's forward and linear sound profile. Vocals come through as intimate and pronounced, while instrumental tracks tend to feel compressed and clustered, leading to a somewhat limited soundstage.

However, the treble has a significant dip, which detracts from the detail and results in a sound that lacks the crispness and clarity that I prefer.

Despite this, the EJ07 maintains a balanced and natural sound overall. Its warmth may not suit my personal taste, but I can appreciate why others might enjoy this tuning, especially considering it's designed with a diffuse field tuning in mind.

Bass (6.5/10)

The bass performance of the EJ07 is good, showcasing a pronounced sub-bass presence. However, it falls short in delivering the texture and punch that are pivotal to my personal preferences.

While it is engaging with several of my tracks, the bass response failed to offer me that 'wow' factor or the head-nodding enjoyment typically with strong and dynamic bass. This experience led me to ponder if this is the characteristic sound of a neutral bass profile.

For the first track, I delved into "Speed of Light" by Jazz Funk Soul. Here, the EJ07 managed to maintain a balanced and neutral reproduction of drum hits, yet it lacked the impact that could have elevated the track further. The presentation was accurate but somewhat lacking in energy.

However, the EJ07 adeptly handled the sub-bass impact in Marilyn Manson's "Killing Strangers," revealing an impressive clarity in frequencies as low as 40Hz. Similarly, "Kashmir" by Marcin showcased its capability to deliver a strong rumble upon the beat drop, affirming their proficiency in sub-bass presence and extension. Despite these strengths, a persistent sense of excitement and punch was conspicuously absent. A slight enhancement around the 100Hz mark could potentially infuse the much-needed vibrancy and fun into the sound profile.

To sum up, the EJ07 delivers a sound that is lean and neutral. While they excel in certain aspects, there's an overarching lack of energy and excitement in their bass performance that leaves something to be desired for those in search of a more engaging listening experience.

Mids (7/10)
The mids of the EJ09 are quite impressive. Instruments and vocals stand out, offering a sense of presence, immediacy, and intimacy.

Listening to male vocals, the EJ09 conveys a rich and warm tone, perfectly exemplified by tracks from Michael Bolton. However, I find the warmth slightly excessive, leading to a somewhat muffled sound.

When it comes to female vocals, they strike a balanced sound. There's an absence of harshness, with the sound leaning towards a neutral and refined quality. Celine Dion's "My Heart Will Go On" is rendered naturally and neutrally, free from any harshness or coloring.

Instruments, while present, don't have as much clarity as one might expect. The track by Joe Hisaishi "Summer" revealed this limitation, with instruments sounding muffled and at times, indistinct. This issue largely stems from a subdued treble response, which we will discuss later.

In summary, the mids performance of the EJ07 are characterized by their lean and intimate quality, with vocals tending towards warm sounding. Instrumentation, on the other hand, appears slightly obscured.

Treble (5/10)
The treble performance of the EJ07 leaves something to be desired. It falls short in capturing the crisp details and the higher frequencies that I highly value in my music. This aspect significantly impacts my listening experience, as I seek out the nuances in my favorite tracks.

For example, in Joe Hisaishi's "Porco Rosso," the initial breaths of the trumpeter, which should be discernible, become elusive. Similarly, Metallica's "Enter Sandman" misses the shimmering quality of the hi-hats, leaving me yearning for more. On the upside, the treble does not exhibit graininess, which is a common flaw in treble-lacking IEMs that often indicates lower-quality drivers.

In conclusion, the treble performance of the EJ07 is underwhelming. The lack of detail is a significant drawback for me.

Imaging and Separation (8/10)

The EJ07 shines in its imaging capabilities. It manages to accurately place elements across the soundstage in many of the tracks I tested, although it slightly misses the mark on capturing the full precision in my favorite orchestral piece, "Porco Rosso" by Joe Hisaishi. Particularly, the movement of the trumpet across the stereo field at the 2:10 mark wasn't as pronounced as I've experienced with other IEMs.

"Chocolate Chip Trip" by TOOL, however, was a revelation. The EJ07 delivered a holographic sound experience that exceeded my expectations, showcasing its strengths in creating a three-dimensional audio landscape.

Gaming tests with Valorant and CSGO further proved the EJ07's adeptness at rendering directional cues like gunfire and footsteps with remarkable accuracy.

When it comes to instrument separation, the EJ07 performs admirably. In tracks like "You Shook Me All Night Long" by AC/DC, each instrument is clearly delineated, contributing to a cohesive yet distinct listening experience.

Overall, imaging and separation are standout features of the EJ07, showcasing its ability to deliver a spacious and well-defined soundstage.

Soundstage (7/10)
The EJ07 offers a pretty good soundstage that greatly enhances the listening experience, providing a holographic sensation across various tracks.

Michael Jackson's "Thriller" serves as an exemplary showcase for this IEM's capabilities. The intricacies of the opening scene—the creaking door, the footsteps, and the distant howl—are rendered with remarkable clarity, immersing the listener in the track's eerie atmosphere. While the soundstage impresses with its width, it falls slightly short in terms of height, leaving a bit of room for improvement.

Another track I explored was "Porco Rosso" by Joe Hisaishi. While the presentation was engaging, it didn't quite achieve the expansive breadth I've experienced with other IEMs. The perceived distance between me and the instruments lacked a certain spaciousness, which slightly detracted from the overall sense of immersion.

In comparison to the EJ09, the EJ07's soundstage is competent, yet it doesn't quite reach the expansive widths that some listeners, including myself, might prefer. Nonetheless, it delivers a solidly good performance that enhances the listening experience across a variety of musical genres and recordings.

EQ Performance (6/10)
The EQ performance of the Shuoer EJ07 presents as somewhat middling straight out of the box. To tailor the listening experience more to my preference, I introduced a high shelf EQ adjustment starting at 5kHz, with an increase of around 3dB. This modification infused the audio output with a significantly more vibrant and dynamic character, bringing to life the higher frequencies that initially felt a bit restrained.

It's worth noting that EQ settings are highly subjective and can vary widely based on individual preferences and the genres of music being listened to. Therefore, I encourage listeners to experiment with the EQ settings to find their ideal balance. Adjusting the decibels up or down from my starting point might yield the perfect audio landscape for your unique ears.

I'd be interested to hear how others have customized their EQ settings for the EJ07 and whether my approach resonates with your audio experience.

Comparison with other IEMs

Shuoer EJ09

Both the EJ07 and the EJ09 are kind of like brothers. One sounds neutral-ish warm while the other sounds neutral-ish bright. The EJ09 sounds a lot better in the technicalities department while the other sounds better in the mids department. Though tonally similar, their distinct sonic characteristics cater to different musical preferences. So it just comes down to whether what genres you listen to. If you prefer instrumentals and orchestral tracks, then the EJ09 is for you. If you focus more on vocals, Pop, and EDM. Then the EJ07 might be for you.

Letshuoer S12 Pro
The Letshuoer S12 Pro stands out as my favored in-ear monitor (IEM) among those I have reviewed. It boasts a balanced and neutral sound signature. However, in terms of technical performance, it falls short compared to the EJ07. Therefore, when deliberating between these two IEMs, one must weigh the importance of imaging and soundstage against tonal quality. The S12 Pro impresses with its exceptional tonality straight out of the box, while the EJ07 offers a more laid-back yet still neutral sound. Additionally, it's worth noting the significant price discrepancy between the two models. Considering value for money, the S12 Pro remains my top recommendation.

Letshuoer S15
The Letshuoer S15 and the EJ07 exhibit similar tuning, albeit with the EJ07 leaning towards a warmer sound profile. I would characterize the S15 as having a more balanced to neutral tuning in comparison. Both models demonstrate commendable technical performance, making it challenging to discern notable differences between them. However, in terms of treble reproduction, the S15 notably outperforms the EJ07. Consequently, the S15 emerges as a versatile IEM, suited for a wide range of musical genres. In contrast, the EJ07 excels particularly with vocal-centric and bright genre tracks, showcasing a more limited scope.

Conclusion
The Shuoer EJ07 stands out as one of Letshuoer's top-of-the-line IEMs, boasting impressive design, build quality, and technical performance that surpass many others I have reviewed. However, a significant drawback that dissuades me from wholeheartedly recommending this IEM is its tuning. The noticeable lack of treble and missing details in some tracks detract from the overall listening experience.

Whether I would recommend the EJ07 ultimately hinges on your specific needs and preferences. If you prefer a warm, neutral sound signature, then this IEM may suit your tastes perfectly. Its exceptional technical performance and sturdy build ensure longevity. However, if you prioritize capturing all the intricate details in your tracks, especially in orchestral compositions, then I would steer you towards alternatives such as the S12 Pro or the EJ09.

419710265_900501024785477_8276805607102325933_n.jpg


TL;DR
Who should consider the Letshuoer EJ09?
• Those who are seeking a superior soundstage and precise imaging.
• Those who love orchestral music and instrumentals.
• Those who favor a bright sound signature
• Those who value intricate audio details in their tracks.



Tonality (6.5/10)
The Letshuoer EJ09 offers an okay tonality. It has a neutral-ish bright sound signature that may lead to ear fatigue during extended listening sessions. However, this sound profile is particularly well-suited for instrumentals and orchestral tracks, aligning with Letshuoer's claim of being the "best in-ear monitors for classical music."

Upon testing with the orchestral track "Porco Rosso" by Joe Hisaishi, the EJ09 displayed crisp and detailed sound reproduction, creating a pleasing audio experience. I noticed that the IEM enhances the instrument sounds, by amplifying the upper frequencies. Thus, this effect may not always produce a natural sound.

Regarding bass performance, the EJ09 performs well, offering a balanced and satisfying bass response. EQ adjustments or low shelf filters are typically unnecessary. Tracks like "Kashmir" by Marcin showcase deep, satisfying bass, while "Killing Strangers" by Marilyn Manson demonstrates the IEM's bass quality in delivering deep and low sub-bass frequencies effectively.

However, when it comes to the midrange, there are some shortcomings. The EJ09 tends to sound a bit shouty, with upper mids that lean towards being overly bright. Male vocal performances may come across as sibilant and overly emphasized, while female vocals fare better but still might not align with personal preferences, appearing somewhat unnatural.

In summary, the Letshuoer EJ09 offers a neutral-ish bright tonality, making it an excellent choice for instrumental and orchestral tracks. However, it may not perform as well with other music genres, particularly Pop and EDM, where it can accentuate sibilance issues in tracks.

Bass (8.5/10)
The Letshuoer EJ09 showcases a commendable bass performance, earning a solid score of 8.5/10. It manages to deliver good sub-bass presence while maintaining a well-textured bass response. However, it may not deliver that "wow factor" often sought after in bassy tracks, such as "Kashmir" by Marcin and "Killing Strangers" by Marilyn Manson, where it appears to lean towards a more linear and neutral presentation, potentially leading to a somewhat unexciting bass experience.

Where the EJ09 truly shines is in reproducing organic instruments like drums and kickdrums. With this type of instrument, it excels by accurately rendering bass notes, staying perfectly neutral. It manages to capture the authentic sound of these instruments, ensuring a faithful representation.

In summary, the Letshuoer EJ09 offers a bass performance that is notably neutral and capable of accurately reproducing low frequencies. While it may not deliver a fun and party experience with bass-heavy tracks, its strength lies in faithfully portraying organic instrument sounds with precision and authenticity.

Mids (7/10)
The Letshuoer EJ09's midrange performance is rated at 7/10, displaying a mixed bag of qualities.

Starting with male vocals, they may not come across as entirely accurate to some listeners. The upper midrange appears emphasized, resulting in a somewhat spicy and sibilant quality on certain tracks like "Gravity" by John Mayer. Higher notes in male vocals, such as those in "Lay Me Down" by Sam Smith, can sound sharp and unnatural.

When it comes to female vocals, the EJ09 introduces added brightness that can accentuate the singer's voice. For instance, in Celine Dion's "My Heart Will Go On," this brightness can bring out the vocal but may also introduce a sense of coloration, potentially affecting the naturalness of the sound. Similarly, when listening to "一念執著" by 故歌和阿兰, both male and female vocals sound impressive but may be slightly overemphasized, which can cause ear fatigue for some listeners.

However, the EJ09 truly excels when rendering instruments. Its added coloration imbues instruments with liveliness and texture. In my favorite orchestral track "Porco Rosso" by Joe Hisaishi, all instruments are rendered with remarkable detail and texture, creating an immersive and enjoyable listening experience.

In summary, the Letshuoer EJ09's midrange performance has its strengths and weaknesses. While it may not excel with certain vocals due to its emphasis on upper mids, it shines when it comes to instrumentals, enhancing their liveliness and texture, particularly in orchestral compositions.

Treble (7.5/10)
The treble performance of the EJ09 is good. It's able to present small details in orchestral tracks, but it falls slightly short when compared to other IEMs in terms of revealing those finer nuances. Some listeners may find that it lacks a bit of sparkle in the top end, which can affect its ability to fully showcase the intricacies of high-frequency elements.

In my assessment of "Porco Rosso" by Joe Hisaishi, the piano and trumpets, along with all the other instruments, are rendered with a neutral and natural tone. While neutrality can be appreciated for accuracy, it may not deliver the same level of engagement and liveliness found in lower-end Letshuoer models, like the S12 Pro.

Furthermore, when listening to Metallica's "Enter Sandman," the hi-hats are presented fairly well at the start of the track but lack the shimmer that some listeners may seek. The treble extension, while decent, may not be as pronounced as desired.

In summary, the treble performance of the Letshuoer EJ09 is good but could benefit from a touch of added sparkle at the top end to enhance its ability to reveal finer details and provide a more engaging listening experience, especially for those who enjoy high-frequency nuances.

Imaging and Separation (10/10)
The Letshuoer EJ09 delivers exceptional imaging and separation, earning a perfect score of 10/10 in this regard.

When it comes to music, particularly orchestral tracks like "Summer" by Joe Hisaishi, the EJ09's imaging capabilities are truly impressive. It excels in precisely locating and positioning all the instruments within the soundstage, creating a highly immersive and detailed listening experience. From left to right, you can discern the exact placement of each instrument, and the separation between them is easily distinguishable.

The EJ09's imaging prowess extends beyond music and into other media. When used for gaming, I played GTA 5 and Valorant, the IEM offers precise imaging during shooting sequences. You can accurately locate your enemies, whether they are firing from behind or from the sides. This precision enhances your gaming experience by providing a clear sense of direction and positioning.

For movie enthusiasts, especially those watching action-packed films like John Wick with bullets firing from every direction, the EJ09 continues to shine. Its ability to spatially represent sound allows you to fully immerse yourself in the movie's audio, making the experience truly impressive.

In summary, the Letshuoer EJ09 excels in imaging and separation across various media, including music, gaming, and movies. Its precise localization of sound sources and clear separation between them contribute to an outstanding auditory experience, earning it a perfect score of 10/10 in this category.

Soundstage (9/10)
The Letshuoer EJ09 boasts an impressive soundstage, earning a solid score of 9/10 in this aspect.

Upon listening to "Thriller" by Michael Jackson, the EJ09 immediately demonstrates its prowess. The track's initial moments, featuring footsteps and howling, come to life with a remarkable sense of space and depth. The audio becomes three-dimensional, providing a truly immersive experience.

In my favorite orchestral track, "Porco Rosso" by Joe Hisaishi, the EJ09 shines again. It masterfully presents the concert stage, allowing you to feel fully immersed in the performance. The spatial representation of the music enhances the overall listening experience.

Switching to gaming and movies, the EJ09 continues to excel. In GTA 5, the bustling streets come to life with the chatter of people and the passing of cars, creating a convincing three-dimensional audio experience. Additionally, the distant sounds of explosions in the game are accurately portrayed, allowing you to gauge their distance with precision.

When testing the IEM with Valorant, similar results are achieved. The EJ09's precision shines through as it accurately represents the dynamics of grenade throws and gunfire, enhancing gaming experience by providing clear and spatially accurate audio cues.

In summary, the Letshuoer EJ09 offers an impressive soundstage across music, gaming, and movies. Its ability to create a three-dimensional audio environment adds depth and immersion to various forms of entertainment, earning it a commendable score of 9/10 for its soundstage performance.

EQ Performance (9/10)
The EJ09 responds well with EQ. With the application of EQ, it becomes possible to fine-tune the EJ09's sound signature. Adjustments such as reducing the peak around 5kHz and 6kHz while adding some sparkle at the top end can be made. These EQ modifications enable you to maintain the core sound characteristics of the IEM while reducing listener fatigue.

The resulting sound is not only more comfortable for extended listening sessions but also enhances the overall audio quality, providing a highly enjoyable listening experience. If you're looking to customize the EJ09's sound to better suit your preferences, experimenting with EQ settings can yield excellent results.

In conclusion, the Letshuoer EJ09's responsiveness to EQ allows for personalized sound adjustments that can significantly improve the listening experience. With the right EQ settings, you can fine-tune the IEM to match your specific preferences and enjoy an enhanced sonic experience with reduced fatigue.

Ultimately, the decision comes down to your individual preference and priorities in audio quality.

Conclusion
The Letshuoer EJ09 shines as an IEM that excels in orchestral music and instrument-based tracks. Its performance truly immerses the listener in the music, providing a remarkable illusion of being present on the stage. It lives up to its claim of being the "best instrument IEM for classical music" with its outstanding soundstage and imaging.

However, the EJ09's price tag of $1,049 may be a deterrent for some potential buyers, especially considering its tonality, which may be perceived as mediocre. This steep price may not align with the preferences of all audiophiles.

In summary, the Letshuoer EJ09 is a superb choice for those who have a deep appreciation for orchestral and instrument-focused tracks and value the immersive experience it offers through its soundstage and imaging. However, if you're seeking a more budget-friendly option without compromising on overall quality, the Letshuoer S12 Pro could be a compelling alternative. Ultimately, your decision should be based on your specific musical preferences and budget considerations.

📝NOTES BEFORE THE REVIEW:
Just so you're aware, my review will focus solely on my personal sound impressions of this in-ear monitor (IEM). I won't delve into the details of the packaging or the accessories that accompany the unit. Additionally, I'll be sharing my personal equalizer (if needed) settings that cater to my specific sound preferences. I'd appreciate your thoughts on how these settings sound on your end - feel free to share in the comments below.

The packaging for the MEST MKIII includes what they call petal eartips and open tips. Frankly, I didn't use them because the open tips don't fit my ears properly, and the petal eartips sounded horrible. I feel that they are limiting the potential of this wonderful IEM.

So, for the purposes of this review, I utilized generic large silicone eartips and an aftermarket cable, as my good friend forgot to include it when lending it to me.

TLDR
Who should consider these IEMs?

  • Those with the budget who simply want to experience top-of-the-line sound.
  • Individuals seeking reference and neutral sound in their music.
  • Audiophiles who enjoy hearing every detail in their tracks without experiencing fatigue.
  • Enthusiasts who appreciate excellent imaging, separation, and soundstage.

Tonality (9.5/10)

The tonality of the MEST MKIII is nearly perfect. Its sound signature can truly be described as neutral and reference-quality. It strikes a delicate balance with the right amount of everything. The sound is smooth, and the bass reaches deep into the subbass.

The level of detail in its sound is truly impressive, capturing the nuances and subtleties of each track I played. What's amazing for me is that this detailed performance doesn't lead to fatigue, which is often times a concern with bright IEMs.

Let’s talk about the bass. It dives deep and adds a rich texture to the music without overwhelming the rest of the frequencies. However, it lacks a bit in quantity for my personal taste, it's essential to note that this is purely a matter of preference. Some listeners may prefer a more restrained bass, especially for critical listening or reference purposes. However, I tend to enjoy a touch more "fun" in my sound, and I wouldn't mind a slightly more pronounced bass for a more enjoyable listening experience.

The midrange is well-pronounced, and perfectly positioned on the soundstage. It neither dominates the mix nor retreats too far into the background. This balance is essential for accurately reproducing vocals and instruments, and the MEST MKIII excels in this regard.

Overall, the MEST MKIII maintains its reference and neutral tuning throughout, and that's one of its standout qualities. Every track I played through this IEM sounded remarkably natural and organic, as if the music was unfolding right in front of me, without any coloration or distortion.

Bass (9/10)
The bass of the MEST MKIII is undeniably impressive, but it leaves me wanting just a touch more energy. However, it's crucial to clarify that this in no way suggests that the MEST MKIII lacks bass or has subpar performance in this department. Quite the contrary, the sub-bass rumble and extension that it offers are among the best I've had the pleasure of experiencing.

Listening to the track "Burn it to the Ground" by Nickelback, the kickdrums hit with an infectious energy and impact that's hard to resist. The sound of cymbals in "Hotel California" from the Eagles' album "Hell Freezes Over" is an experience unto itself. The rumble it produces genuinely brought a smile to my face.

"Fragments of Time" by Daft Punk featuring Todd Edwards features a bassline that covers the entire spectrum, putting the MEST MKIII's capabilities to the test. And the result is truly pleasing to the ears, as it captures the full depth and richness of the bass.

Additionally, when I played "Kashmir" by Marcin, the MEST MKIII delivered bass so deep that it makes my heart pound. The quality of bass from this IEM is exceptionally well-tuned, demonstrating its prowess in handling low frequencies with precision and power.

While I noted a slight desire for more energy in the bass of the MEST MKIII; again, it’s purely a matter of personal preference. The bass it does provide is of outstanding quality, with impressive sub-bass extension and rumble that elevates the listening experience. The MEST MKIII excels in reproducing bass-heavy tracks, delivering a depth and impact that will satisfy even the most discerning audiophiles and bass enthusiasts.

Mids (10/10)
The midrange of the MEST MKIII is, in a word, perfect. I couldn't find a single fault or complaint about it. The balance between distance and forwardness in the tracks I played was spot on. Both male and female vocals sounded incredibly natural and perfectly clear. The separation between vocals and instruments was executed flawlessly.

One track that truly showcased the MEST MKIII's ability to handle male vocals exceptionally well is "Crying Shame" by The Teskey Brothers. The instruments and vocals in this song sounded crystal clear and impeccably separated, allowing the listener to savor every nuance of the performance.

Speaking of instruments, what truly astonishes me about the MEST MKIII is its ability to present every detail of the sound effortlessly. There were moments during my casual listening sessions when I heard the subtle crash or slap of an instrument that I had never noticed before. It's remarkable how this neutral IEM can produce such high-quality sound in such a compact form factor.

The MEST MKIII's neutral sound signature also brings a touch of lushness, richness, and a hint of warmth to the overall tone. While some listeners might perceive it as slightly warm, it genuinely embodies what I consider to be the essence of "neutral." This balance adds to the musicality of the IEM without sacrificing accuracy or transparency.

Generally, the midrange performance of the MEST MKIII is nothing short of exceptional. Its ability to faithfully reproduce vocals and instruments, with impeccable separation and detail, sets a high standard for neutral IEMs. Whether you're a fan of male or female vocals or enjoy dissecting the intricacies of instrumentals, the MEST MKIII delivers an audiophile-grade experience that will leave you thoroughly impressed.

Treble (10/10)
The treble of the MEST MKIII is also perfect. It's free from any hints of peaks, sibilance, or listener fatigue, even during extended listening sessions. What sets it apart even further is its ability to produce a sparkling quality at the top end of the spectrum, tailored precisely to my listening preferences. It's this exceptional treble performance that made me truly fall in love with the sound signature of this IEM.

Listening to tracks like "Porco Rosso" by Joe Hisaishi was a revelation. Every instrument in that live performance was presented in a breathtaking manner. The cymbals, pianos, trumpets, and more were effortlessly rendered with meticulous detail, making the music a sheer pleasure to the ear.

For testing sibilant tracks like "Wolves" by Selena Gomez, where the mix tends to be bright, the MEST MKIII proved to be a game-changer. Despite the inherently bright mix, this IEM managed to maintain a balanced presentation, avoiding any harsh sibilance that could detract from the listening experience.

And when it came to evaluating treble extension, "Enter Sandman" by Metallica provided a perfect testing ground. At the beginning of the track, the MEST MKIII showcased its prowess by flawlessly reproducing the hit of the hi-hats with long echoes that I had eagerly anticipated. It's an extraordinary treble performance that adds an extra layer of excitement to the music.

The treble performance of the MEST MKIII is simply outstanding. Its ability to maintain a clean, balanced, and fatigue-free presentation while still delivering sparkling highs is a testament to its audio prowess. Whether you're enjoying delicate acoustic performances or rocking out to high-energy tracks, the MEST MKIII's treble performance will elevate your listening experience to new heights, leaving you in awe of its exceptional capabilities.

Imaging and Separation (10/10)
The imaging and separation provided by this IEM are genuinely one of a kind, surpassing even some high-end headphones and speakers. What truly sets it apart is the effortless way it presents these qualities, making it a standout in the world of audio.

Listening to the track "Silent Sea" by Joe Hisaishi was a revelation in itself. The MEST MKIII allowed me to distinguish every instrument being played in the track with remarkable precision. Each individual instrument was so well separated by this IEM that it even outperformed my Hifiman Arya Stealth headphones in this category. It's a testament to the MEST MKIII's ability to paint a vivid sonic landscape that lets you explore every musical detail.

Another track worth mentioning is "Summer" by Joe Hisaishi. The imaging in this track seems to go everywhere, and what's truly astonishing is that the MEST MKIII effortlessly located every instrument, from left to right, creating a three-dimensional sonic panorama that's truly immersive.

But the MEST MKIII's capabilities extend beyond just music. I decided to put it to the test by playing a few shooting games like Counter Strike 1.6 and Valorant. To say that I was impressed would be an understatement. The technical prowess of this IEM became apparent as it delivered pinpoint accuracy in sound placement, helping me to locate opponents and crucial audio cues with astonishing precision. It's safe to say that the MEST MKIII exceeded my expectations when it came to gaming performance as well.

In conclusion, the MEST MKIII's imaging and separation capabilities are simply exceptional. It not only competes with but often surpasses the performance of high-end headphones and speakers in this regard. Whether you're listening to music, watching movies, or gaming, the MEST MKIII's ability to create a vivid, precise, and immersive audio experience will undoubtedly leave you in awe of its technical capabilities.

Soundstage (9.5/10)
The soundstage of the MEST MKIII is also outstanding, and I can hardly believe I'm saying this on an IEM. It manages to create an immersive soundstage that pulls you into the heart of the music.

One track that beautifully showcases the MEST MKIII's expansive soundstage is "Thriller" by Michael Jackson. Right from the start of the track, it's as if there's someone walking right in front of me. The opening of the door, the footsteps, and the eerie howling of the wolves are all rendered with such spatial precision that it's like experiencing a live performance. The MEST MKIII manages to convey depth, width, and height with remarkable accuracy.

Listening to the classic track "Hotel California" by the Eagles further illustrates the MEST MKIII's prowess. The width and height of the stage in this track are perceptible through this IEM, allowing you to immerse yourself in the intricate details of the song's arrangement. It's an experience that truly elevates the enjoyment of timeless classics.

For a different perspective, I also tuned into "The World of Sound" by Dolby on YouTube. This simple sound demo of Dolby Atmos, when experienced through the MEST 3, left a lasting impression. It showcased the IEM's ability to reproduce spatial audio with exceptional clarity and precision. It was like having a personal Dolby Atmos experience right in my ears.

The soundstage performance of the MEST MKIII is a testament to its audio excellence. It defies expectations by creating an immersive and expansive soundstage that adds a new dimension to your listening experience. Whether you're enjoying cinematic soundscapes or classic hits, the MEST 3's ability to convey depth, width, and height with astonishing precision will leave you truly impressed.

EQ Performance ( - )
The MEST MKIII doesn't require EQ to shine. In fact, it already offers an exceptional sound experience right out of the box.

For those who would still like to EQ, you have the option to experiment with a slight low shelf boost around 125Hz, perhaps adding just 1 dB or 2 for a noticeable impact. However, it's worth noting that such adjustments are purely optional, as the MEST MK3's default sound is already extraordinary.

Comparison to other IEMs
First and foremost, the price contrast between the MEST Mk3 and the IEMs I've reviewed is staggering. It's not a fair comparison to begin with. However, perhaps in the future, more companies will send high-end IEMs for me to evaluate and compare.

Letshuoer S15
One IEM that immediately comes to mind in this comparison is the S15, priced at approximately $325. In contrast, the MEST MKIII comes in at around $1,919, nearly six times the cost. Despite the price difference, the S15 exhibits a slightly warm tonality, lacking a shimmer at the top end, yet maintaining a balanced-neutral sound. On the other hand, the MEST MKIII embodies pure neutrality in my opinion.

In terms of technical prowess, the MEST MKIII takes the lead, although not by a substantial margin. Both IEMs excel technically. In fact, unless you're a discerning listener, you may not readily discern the distinctions. However, the MEST MKIII effortlessly delivers an immersive listening experience, drawing attention to its exceptional imaging, separation, and soundstage, even if you're not fully focused on the music.

Apart from these differences, they share many similarities and qualify as excellent performing IEMs, both deserving a spot in your top 10 IEMs list.

Letshuoer S12 Pro
The S12 Pro holds a special place as the first IEM I reviewed and fell in love with. It features a bright-neutral sound signature that particularly shines on orchestral tracks. When comparing it to the MEST MKIII, I still favor the S12 Pro's tonality, primarily due to my affinity for orchestral music. However, it's important to note that the technical capabilities of the S12 Pro fall short in comparison to the S15 and the MEST MKIII.

In the realm of technical performance, the MEST MKIII takes a commanding lead. Therefore, if you're searching for a budget-friendly option that still offers good overall performance, the S12 Pro is an attractive choice, especially considering its current price of just $139 on Letshuoer's website. Alternatively, the MEST MKIII stands as an end-game neutral/reference IEM, excelling as an all-rounder in its own right.

Conclusion
The Unique Melody MEST MKIII CF is nothing short of an astounding IEM that, until recently, I could only dream of getting my hands on. A special shoutout to RemedyMusic for graciously lending me his unit for this comprehensive review.

In terms of sound quality, the MEST MKIII delivers a neutral-reference signature that stands as a benchmark of excellence. Its technical performance sets it apart and places it firmly in the realm of end-game audio.

However, it's important to be candid about the price tag attached to the MEST MKIII. It's an investment suited for those who are in pursuit of the pinnacle of audio nirvana and have a substantial budget to allocate. For those of us embarking on the IEM journey, it's crucial not to let this IEM spoil you, as it may tempt you to part with $2000 😆.

In summary, my wholehearted recommendation for the MEST MKIII extends primarily to individuals who have the financial means to afford this premium experience. For those seeking more budget-friendly options, alternatives like the S12 Pro or the S15 are worth considering and can provide exceptional listening experiences without breaking the bank.

TLDR
Who should consider these IEMs?
  • If you enjoy listening to music at high volumes, these IEMs shine the most when played loudly.
  • They offer a balanced and neutral sound profile with a hint of metallic timbre, which may or may not suit your personal preference.
  • These IEMs excel in terms of technical performance, making them a fantastic choice for gamers and movie lovers, surpassing expectations.
  • If you're a fan of female vocals in your music, these IEMs deliver an outstanding listening experience for such tracks.
  • You don't need a powerful amplifier to make these IEMs sound their best; even the Apple dongle works well.
  • If you're into mid-range frequencies, these IEMs perform exceptionally in that range.
  • In essence, they are versatile and can handle a variety of music genres and applications.

Tonality (9/10)

The Letshuoer S15 offers a finely tuned and naturally sounding tonality. Its sound signature leans towards a balanced-neutral profile with a slight peak around the 5kHz range. This peak may or may not be bothersome to some listeners, and personally, I find it a bit irksome as it tends to emphasize sibilant sounds, particularly 'S' sounds.

In my listening tests, I explored a wide array of music genres from my collection, and I was pleasantly surprised to find that this IEM performed admirably across the board, ranging from good to excellent. It truly embodies the versatility of a "jack of all trades."

However, I did notice that the bass response of this IEM falls a bit short in terms of power and quantity. While the sub-bass extends impressively deep, I believe a few extra decibels in this department could enhance the overall listening experience.

Moving on, I observed that this IEM doesn't deliver its best performance at low volumes. At lower volume levels, it tends to sound somewhat muffled, and the metallic timbre remains present. I'm uncertain if this issue is related to the IEM itself or if it simply excels when played at higher volumes. Regardless, it's clear that this IEM caters to those who prefer listening at louder volumes.

Bass (8.8/10)
The Letshuoer S15 delivers a commendable bass performance, especially in terms of sub-bass extension. However, it could benefit from a bit more power. When I listened to "Kashmir" by Marcin, I could feel the rumble in the lower end of the track, a rare quality among the IEMs I've encountered.

When it comes to rendering organic instruments like congas and drums, these IEMs accurately reproduce the hits, offering a pleasing auditory experience. Nevertheless, I would appreciate an additional 2 decibels in the bass region, specifically around 125Hz. In the track "Hotel California" by the Eagles from the album "Hell Freezes Over," the IEMs accurately capture the beginning of conga hits but fall short in terms of quantity.

Transitioning to electronic tracks such as "Paint the Wall" by Killrude and "Surface" by Aero Chord, the bass becomes a source of enjoyment and excitement. Coupled with high volume levels, it can make your head nod and immerse you in the music.

Mids (9.5/10)
The mids of the Letshuoer S15 is quite remarkable. This is where this IEM shine. Both female and male vocals were able to present it naturally and with impact. Let’s first discuss male vocals.

When listening to “Gravity by John Mayer”, I can feel the intimacy, richness, and impact of his voice. It’s clear and detailed. The instruments being played also sounded very natural and elegant. It really made me want to listen to more vocal focused tracks.

I also listened to Frank Sinatra’s “Have Yourself a Merry Little Christmas” because of the low end voice. Still, it was able to present it wonderfully. Natural and distinct.

Moving on to female tracks, I listened to “当 by 赵乃吉”. The female’s voice is intimate, sweet, clear and elegant. I’m actually shocked at how it sounded at first, made me pause and wonder how it was able to perform at such level of quality.

When listening to rock songs like “You Shook Me All Night Long” by AC/DC. Electric guitars sounded natural and powerful. Instrumental tracks like “Early Summer Rain” by Yasuharu Takanashi, the plucking of the pipa is really immersive and natural.

Truly, this IEM will exceed your expectations when it comes to its midrange performance. Good job Letshuoer!

Treble (9/10)
The Letshuoer S15 offers an impressive treble performance. It excels in presenting high frequencies with remarkable clarity, devoid of any noticeable peaks or irritation. Instruments like cymbals come across as natural and organic in their sound reproduction.

While there is a slight peak at the 5kHz range when listening at moderate levels, this issue tends to resolve itself at higher volumes. Some residual sibilance remains, but it is unlikely to pose a significant problem for most listeners.

If I were to nitpick, I'd appreciate a touch more shimmer in the upper-end. In my listening experience with orchestral tracks like "Summer" and "Porco Rosso" by Joe Hisaishi, I noticed that some of the cymbals and high hats lacked the shimmer and sizzle that I personally prefer. Nonetheless, the overall treble performance remained highly enjoyable.

Imaging and Separation (9.5/10)
The imaging and separation capabilities of these IEMs are truly exceptional, almost akin to having Dolby Atmos in an IEM. Every instrument finds its precise location in the audio landscape.

When listening to orchestral tracks, the IEMs excel at presenting a remarkable sense of separation and direction. The instruments are positioned accurately, creating an immersive listening experience that does justice to orchestral compositions.

In addition to music, I also tested these IEMs in gaming scenarios such as Valorant and Counter Strike 1.6. They impressively render in-game sounds, including footsteps, gunfire, and explosions, providing a clear and immersive gaming experience.

Soundstage (8/10)
The Letshuoer S15 offers a good soundstage. I had the chance to watch a few clips from John Wick using these IEMs, and it was a fun and immersive experience. The sound of gunfire, running, and passing cars was quite impressive. However, it still falls short in terms of vastness and depth.

When I listened to "Porco Rosso" by Joe Hisaishi, I noticed that the accuracy of cymbal crash distance could be improved. It felt somewhat clustered in that regard.

Nonetheless, for an IEM, it's quite rare for me to commend its soundstage capabilities. The Letshuoer S15 managed to exceed my expectations in this department.

EQ Performance ( - )
I didn't find the need to EQ this IEM, as it sounded excellent right out of the box. However, if you're inclined to use EQ, I would recommend adding a slight bass shelf starting at 125Hz, perhaps around +1.5 dB, and making a minor adjustment around 5kHz, reducing it by approximately -1 dB. It's important to note that these suggestions are purely based on personal preferences and nitpicks.

In summary, there's no pressing need for EQ adjustments; the IEM already delivers impressive sound quality without any modifications.

I'd like to draw a direct comparison between the Letshuoer S15 and its sibling, one of my favorite IEMs that I've reviewed - the Letshuoer S12 Pro. When comparing them side by side, there are noticeable differences in their sound signatures.

The S12 Pro leans slightly towards a balanced sound signature with a bit more emphasis on treble. This quality makes it particularly appealing for orchestral tracks, where the added treble enhances the listening experience. On the other hand, the S15 showcases a more neutral sound signature, which may be less exciting but brings out its uniqueness in sub-bass performance.

In terms of technical capabilities, both IEMs are quite similar, but the S15 has an edge in imaging, separation, and soundstage. It delivers an immersive and accurate listening experience, setting it apart from the S12 Pro, which tends to sound more compressed and has a narrower soundstage.

Regarding tonality, in my personal opinion, the S12 Pro still holds the crown. Its performance shines on orchestral tracks, though it may sound slightly harsh with both male and female vocals. Lowering the volume can alleviate this issue, making it a solid choice for those who prefer moderate listening volumes.

In conclusion, if your focus lies on midrange performance and technical capabilities, the S15 is the clear winner. Its natural and neutral sound, especially for female tracks, coupled with unmatched immersiveness, make it a standout choice. On the other hand, the S12 Pro excels in tonality, particularly for orchestral and various music genres, but you may need to lower the volume to avoid excessive brightness and harshness.

Conclusion
In conclusion, the Letshuoer S15 proves to be an impressive IEM that left a lasting impression on me. It performs exceptionally well and has provided one of the most satisfying listening experiences I've had in a long time. However, it's worth noting that this IEM truly shines when played at loud volumes, which contrasts with my personal preference for lower volume levels. Nevertheless, if you're willing to crank up the volume, you won't be disappointed with this IEM.

Now, the question arises: Should you choose the Letshuoer S15, given that the Letshuoer S12 Pro is available at nearly half the cost and shares many qualities with its more expensive sibling? The answer largely depends on your preferences. If you enjoy listening at higher volumes, the S15 is definitely worth the $329 investment. However, if you tend to listen at lower to moderate volumes, I'd recommend going for the S12 Pro.

If your priority lies in technical capabilities such as imaging and soundstage, then the S15 upgrade might be worth considering, although the differences between the two models aren't substantial. If you have a penchant for orchestral or instrumental tracks, the S12 Pro is the better choice for you.

Speaking personally, if I had to choose one IEM, I would still opt for the S12 Pro. It continues to amaze me every time I listen to it, and I find its build quality superior to that of the S15.

LETSHUOER DZ4 - A Review By Zeng

363862692_305431545193972_7945050116317632873_n.jpg


Tonality (5/10)
The tonality of the DZ4 is mediocre, primarily due to its commendable performance in the treble range. It successfully renders both male and female vocals in the highs, but the mid-range lacks definition. For instance, male vocals lack depth and impact, appearing thin, unexciting, and unnatural, largely due to the recessed mids affecting the vocal presentation. An example is Michael Bolton's "When a Man Loves a Woman", where his robust and impactful voice lacks the expected richness and strength. Regrettably, this IEM falls short of expectations.

In the case of female vocals, the higher pitch in their voices fares better, though they still sound thin and lack vibrancy. Despite these shortcomings, female vocals are rendered more naturally and transparently than their male counterparts. An exemplifying track is "Cupid" by FIFTY FIFTY, where the voices retain their natural charm. However, the recessed mids make the sound seem disproportionately boosted in the treble frequencies, which can be irksome.

In terms of instrumentals, the DZ4's performance is run-of-the-mill. The piano tones are decent, but the sound of cymbals crashing comes across as artificial and cheap. The trumpet notes are acceptable, albeit somewhat nasally. The drum and conga hits are uninspiring and devoid of energy, lacking impact and coming across as mere light slaps. In short, it's quite disappointing. On the whole, the instrumental performance of this IEM can at best be described as mediocre.

In conclusion, the DZ4's tonality shines only when dealing with female vocals or vocals with higher pitches.

Bass (3/10)
The bass performance of the DZ4 leaves much to be desired. Its output is so faint that it's almost comparable to the bass from my iPhone speakers. The bass lacks both impact and rumble, falling well short of satisfying standards. I've tested other IEMs with subtle bass that nonetheless managed to deliver pleasing and high-quality sound, but the DZ4 fails to achieve this.

When listening to Marilyn Manson’s “Killing Strangers”, the robust bass that characterizes the start of the track was virtually absent in this IEM. It was light and lacked any significant impact. Similarly, the track “School’s Out” by The Brand New Heavies lacked the low rumble that should appear at the track's outset, making it sound underwhelming and taking away from the enjoyment of bass-heavy tracks.

Shifting focus to instrumentals, while listening to “You Shook Me All Night Long” by AC/DC, the sound of the drum at the start of the track was more akin to a light pat than a solid hit, failing to capture the natural sound of drums that I anticipated.

In summary, the bass of this IEM is seriously lacking. It gives the impression of bass emanating from a phone speaker rather than a high-quality audio device. If you're considering this IEM for movie watching or gaming, I'd strongly advise exploring other options.

Mids (5.5/10)
The mid-range performance of the DZ4 is passable at best. Female vocals outshine male ones due to the boost in upper mids and treble, resulting in a more natural and technically superior sound for female vocalists. On the other hand, male vocals lack the depth and impact that they should ideally possess.

I listened to "Cupid" by Fifty Fifty and "My Heart Will Go On" by Celine Dion. Both tracks did a decent job of presenting the singers' voices naturally and convincingly. However, a noticeable dip in the midrange at around 1 kHz made the overall sound feel somewhat lackluster.

Turning to male vocals, I listened to Michael Bolton’s “When a Man Loves a Woman”. The track failed to convey the richness and commanding presence that his voice usually projects at the beginning of the song. While the highs were reasonably clear, the lows were not, resulting in a lack of emotional resonance and impact. When I listened to male vocalists with higher pitches, such as Sam Smith and Charlie Puth, their voices sounded better than those of male vocalists with lower pitches. However, even their vocals came across as nasal and unnatural.

To reiterate, the recessed mids are a point of irritation for me and compromise the authenticity of the sound when singers are performing.

Treble (6.5/10)
The treble performance of the DZ4 is fairly satisfactory. It manages to avoid sibilance and doesn't induce fatigue during extended listening periods.

However, when I listened to my favorite orchestral tracks, namely Joe Hisaishi’s “Porco Rosso” and “Summer,” I found the instrumentals to be less impressive. The piano sound was acceptable but lacked natural resonance. The cymbal crashes sounded dreadful and synthetic, coming across as nasal and artificial. The trumpets were decent but again failed to deliver a natural sound. I noted that the top end of this IEM appeared poorly tuned and came across as artificial, while the upper treble ranges were passable. The treble performance on female vocals was reasonably good.

In conclusion, this IEM does a decent job in the upper treble ranges. However, it lacks sparkle and detail at the top end, resulting in a sound that seems artificial and unnatural.

Imaging and Separation (5/10)
The imaging and separation capabilities of the DZ4 are average at best. During my listening sessions with orchestral tracks, it managed to depict left-to-right movement decently. However, it fell short in delivering a fully immersive experience. While listening to “Hide” by Juice WRLD, the track's intended 360-degree effect was not as engrossing as expected.

To put its imaging and separation to the test, I also played some FPS games. The DZ4's performance was subpar in this regard. It was able to deliver decent sound cues when enemies were approaching from the left or right, but failed to accurately pinpoint their locations when they were coming from behind.

In summary, the DZ4's imaging and separation capabilities are merely average. Gamers who value precise locational accuracy for in-game enemies may want to consider other IEM options.

Soundstage (3/10)
The soundstage of the DZ4 is highly disappointing. There is no sense of space or depth while listening to my orchestral tracks. It gives the impression that all instruments are confined to a small room, even when the music is intended to simulate a concert hall atmosphere. The limited dynamic range of this IEM is a significant factor undermining its soundstage quality.

Additionally, when using this IEM for FPS games such as Counter Strike 1.6 and Valorant, the distances between sound cues like footsteps and enemy gunfire are poorly positioned and not at all convincing. Enemy footsteps sound muffled and inaccurately located.
In conclusion, the soundstage of this IEM is substandard. If you're seeking an immersive experience for your orchestral tracks, I wouldn't recommend the DZ4.

EQ Performance (7/10)
The DZ4's EQ capabilities and performance are commendable. I was able to tailor its sound to match my preferences, addressing the IEM's initial shortcomings. Primarily, I introduced a low shelf bass boost around 100hz and 80hz. I also applied a high shelf filter at approximately 5500hz to enhance the upper treble to the top end. I'm keen to hear your thoughts on my EQ adjustments, so please share your feedback in the comments section below.

Comparison to other IEMs
LETSHUOER D13

The D13 and DZ4, despite being similarly priced, offer dramatically different audio experiences. The D13 outperforms the DZ4 by a significant margin, delivering a natural, smooth, and non-fatiguing sound, with a particularly impressive midrange performance. Unlike the DZ4, which performs well only for female vocals, the D13 handles both male and female vocals adeptly. Adding to its flexibility, the D13 provides gold and silver nozzles to customize your listening experience, offering either a brighter sound or a more natural presentation. Although the DZ4 is priced at $89 and the D13 at around $119, the marked improvement in audio quality makes the D13 well worth the additional cost.

LETSHUOER S12 Pro
The S12 Pro, a superior model to the D13, delivers some of the finest orchestral performances I've experienced in an IEM. Although it commands a significantly higher price than the DZ4, I personally believe the S12 Pro is worth every penny. Its sound quality is excellent across nearly all genres, and orchestral pieces are simply enchanting to the ear. It offers a well-balanced, natural, and transparent sound, outclassing the DZ4 in all aspects. I would advise spending an additional $45 for the S12 Pro without hesitation, as it provides a far more satisfying audio experience than the underwhelming DZ4, which may leave you dissatisfied despite its lower cost of $89.

Conclusion
At around $89, I would recommend considering either the D13 or the S12 Pro over the DZ4, as both alternatives outshine the DZ4 in every performance category. Personally, I found the DZ4 to be one of the least impressive IEMs I've encountered. Its light bass, recessed mids, and low-quality treble fail to justify the price or the design aesthetics. This unit was a letdown for me, and I sincerely hope that the manufacturers consider retuning this IEM.

358975150_1478792726265106_1086314082432837089_n.jpg


Tonality (5/10)
The CVJ KE-S has an average tonality, delivering passable rendition of my tracks. It was able to correctly reproduce both male and female vocals, though they sound hollow, lacking naturalness and energy. Male vocals seem thin, while female vocals appear veiled and tamed, losing presence due to insufficient treble.

Listening to my favorite orchestral tracks, "Porco Rosso" and "Summer" by Joe Hisaishi, the tonality of instruments like the piano, trumpet, and saxophone is acceptable. However, the details are veiled and muddy, seeming compressed and lacking presence.

The CVJ KE-S's redeeming feature is its bass, which offers a pleasing quantity and quality, giving a rich, enjoyable sound. The low-end performance is admirable, though high-frequency instruments like drums fall short.

In sum, the CVJ KE-S has average tonality, not excelling in any particular area but also avoiding any harsh or irritating peaks.

Bass (8/10)
The bass of the CVJ KE-S is actually pretty impressive. It delivers quality, impactful bass that superbly complements my bass-heavy tracks. All aspects of the bass - the lows, the thump, and the rumble - are presented with satisfying gusto.

When I listened to "Killing Strangers" by Marilyn Manson, the track started with a deep and powerful bass. The seal of the IEM enhances the bass output, leading to a fuller and richer sound. Similarly, during "School's Out" by The Brand New Heavies, the IEM impeccably presented the deep lows of the bass guitar at the track's outset. The rumble effortlessly reached the low bass extensions of the IEM, which was truly astonishing.

Turning to the instrumental tones, the sound produced by the drums, congas, and bass drums is commendable for its great bass. However, the tonality falls short of expectations. The instruments sounded somewhat unnatural, likely a consequence of this IEM's warm sound signature.

Mids (4/10)
The midrange performance of the CVJ KE-S could certainly use some improvements. It disappointingly fails to deliver clear and distinct male and female vocals, offering instead a sound that is murky and somewhat shrouded. The absence of a crisp, detailed rendering is quite evident and detracts from the overall quality of this IEM. The mids appear to be withdrawn or "recessed", resulting in a less engaging listening experience.

Interestingly, male vocals tend to be slightly better presented than their female counterparts. The CVJ KE-S's warm sound signature imparts a richness to lower frequencies typically associated with male voices. Hence, despite the overall lackluster mids, the IEM still manages to present an acceptable - if not exceptional - performance for male vocals.

Take for instance "When a Man Loves a Woman" by Michael Bolton. His voice appears suppressed in the mix, suggesting a recessed soundstage. It seems as if there's a dip in the frequency response around 1kHz. Whether this is a conscious tuning decision or a limitation in the earphone's driver technology, it results in a suboptimal performance for this particular track.

Another song where the dip in the mids is prominently noticeable is "You Shook Me All Night Long" by AC/DC. The recessed midrange vocals of Brian Johnson at the start of the track are conspicuous and detract from the overall quality of the track.

Lastly, female vocals, such as in Celine Dion’s "My Heart Will Go On", also appear recessed and veiled. The impact of her voice is not properly conveyed, and the energy in her performance seems stifled by the warm signature. This issue is noticeable in almost all the female-centric tracks.

Treble (3.5/10)
The treble performance of the CVJ KE-S is far from satisfactory. It falls short in delivering detailed and authentic sound in both instruments and vocals. A notable lack of vibrancy, particularly in the 12kHz range, results in a dull sound with an absence of clarity. This contributes to an overall dark and warm sound signature.

Listening to orchestral tracks like "Porco Rosso" and "Summer" by Joe Hisaishi further underscored these issues. The sounds of distant instruments are hardly noticeable. The crashing cymbals lack detail and don't stand out in the track as they should. A recessed upper treble range results in a dull and dark sounding track. The strings in the violin, too, are not well articulated.

When it comes to vocal performance in the high notes, the lower to mid treble exhibits a lack of energy, causing the vocals, especially in the 3kHz range, to also sound recessed. The vocals feel distant and lack the intimacy one would hope for.

In terms of utility in gaming, I tried using the IEM to listen for footsteps and distant shooting in games like Counter Strike 1.6 and Valorant. The IEM failed to present the distant footsteps clearly. It lacked detail and resolution, which were crucial for an immersive gaming experience.

Imaging and Separation (4.5/10)
The CVJ KE-S also disappoints when it comes to imaging and separation. Most of my tracks, especially the orchestral ones, suffer from a lack of clear distinction among the various instruments being played. This results in a sound reminiscent of a mono speaker, with all the elements seeming to blend together.

This is particularly noticeable when listening to tracks like “Hide” by Juice WRLD and “I Want To Break Free” by Queen, both of which I tested for their 360-degree effect. While the IEM did manage to deliver a semblance of this effect, it fell short of providing the immersive experience I was hoping for. Furthermore, the dynamic range of the IEM also leaves much to be desired.

Using this IEM while playing FPS games is equally frustrating. The accuracy in distinguishing between left and right is compromised when it comes to detecting enemies' footsteps, which tend to blend together. The sound of gunfire suffers from a similar issue.

Soundstage (3/10)
The soundstage presented by the CVJ KE-S is also quite disappointing. There's a notable lack of depth in my orchestral tracks, with all the instruments appearing to be playing from the same location. This deficiency in spatial distribution greatly detracts from the listening experience.

The situation is similar when it comes to gaming. While playing FPS games, the IEM fails to provide a convincing illusion of distance and space between my enemies and teammates' footsteps. This makes it challenging for me to accurately discern their locations, hampering gameplay.

EQ Performance (5/10)
The equalizer (EQ) performance of the CVJ KE-S is fairly average. I was able to enhance the treble, which I felt was lacking, and give the top end of the spectrum around 12kHz more sparkle and energy. I also boosted the mids to make them more lively and to counteract their recessed sound.

Overall, these adjustments improved the sound, though the end result was nothing extraordinary. I encourage you to try these settings and share your thoughts in the comments section below.


358934924_612489750869440_5945329142653978796_n.jpg


Comparison with other IEMs
Priced at just $9, the CVJ KE-S is one of the most affordable IEMs I've ever tried. Most of my experiences have been with IEMs valued at around $20 or perhaps slightly more, but rarely anything less than $10. Therefore, a direct comparison might not be entirely fair.

However, I've reviewed both the Tanchjim Tanya DSP and the NiceHCK EB2S Pro. Even though the latter is an earbud and technically it's not a direct comparison, I'd highly recommend checking them out. Both are priced around $25 and, in my opinion, offer superior value for the money spent.

Conclusion
In conclusion, at the modest price of $9, I would strongly encourage you to save your money and invest in better IEMs or earbuds instead. The Tanchjim Tanya DSP and the NiceHCK EB2S Pro are both excellent alternatives that offer superior tonal and technical sound qualities.

Although the CVJ KE-S is an affordable option, its overall sound quality leaves much to be desired. It lacks many redeeming features that would make me comfortable recommending it to others. Both the technicalities and tonality are at best, average.

The only feature that stands out is its bass. While it suits my personal taste quite well, I wouldn't consider this enough to compensate for its shortcomings. Its performance in gaming or movie watching scenarios is unlikely to impress you.

So, I would say: save your money and invest wisely in your audio gear. The right investment can greatly enhance your listening experience.

I'd appreciate your thoughts on how these settings sound on your end - feel free to share in the comments below.

The Tanchjim Tanya DSP uses a Type-C connector for the 'ease' of smartphone use. However, if you are currently using an iPhone, you will have to look elsewhere. Moreover, I used the default large silicone eartips for this review, and the sources I used were both my M1 iPad Pro 2021 version and my Xiaomi Mi 9T Pro, as they both come with a Type-C connector. For the iPad, I utilized Apple Music as my streaming service, while for the Xiaomi, I used UAPP connected to Qobuz as my streaming service.

Tonality (7.5/10)
The tonality of the Tanchjim Tanya DSP is impressive, especially in the vocals, with both male and female voices well pronounced, transparent, and authentic. When listening to Michael Bolton's 'When a Man Loves a Woman,' the level of clarity and depth in his voice is engaging and energetic. The emotions in his voice are also very present with this IEM, and I'm genuinely impressed with its vocal performance considering its price.

Similarly, female vocals, such as Lady Gaga's 'Always Remember Us This Way,' sound clear and natural. There are no hints of boosted treble or excessive warmth; instead, her voice is rich, smooth, and transparent throughout.

Moving on to instrumentals, in the track 'Serious Business' by Jazz Funk Soul, let's start with the bass. In my opinion, the bass of this IEM is too boosted, resulting in an unnatural and thumpy sound. Another track I tested is 'School's Out' by The Brand New Heavies, where the lows are excessively boosted, making it sound bloated.

On the other hand, the detail presentation of this IEM is nothing too special. Instruments in orchestral tracks don't shine as much and seem overshadowed by the powerful bass. Listening to 'Porco Rosso' and 'Summer' by Joe Hisaishi, not all instruments can be heard clearly, lacking some spiciness in the higher frequencies. However, the tonality of the instruments remains natural and not muddy in any way.

Overall, the tonality of this IEM is pretty good. What makes it special is its extremely well-tuned vocal performance at a relatively affordable price.

Bass (6.5/10)
The bass of the Tanchjim Tanya DSP is acceptable; it delivers good quality but doesn't offer anything particularly remarkable. The main concern lies in the excessive boost in the lows, probably around 125Hz. This reminds me of another IEM I reviewed, the CCZ Warrior, which also suffered from a similar issue with its bass but lacked the tonal balance of the Tanchjim Tanya.

For listeners who enjoy genres like EDM, R&B, and heavy bass-focused music, this IEM can be enjoyable, particularly when watching movies or playing casual shooting games. However, in terms of subbass performance, I wasn't particularly impressed. In the track "Killing Strangers" by Marilyn Manson, the low rumbling sound I sought didn't extend well. Nevertheless, the strong mid and upper bass of this IEM might create the illusion of a powerful bass experience.

It's worth noting that the bass impact of the Tanchjim Tanya is indeed robust, but it can sometimes lead to headaches when used for an extended period.

Turning to instrumentals, the bass performance of this IEM also falls short. When listening to "Serious Business" by Jazz Funk Soul, the track becomes muddy due to the overwhelming thumping bass. Similarly, in "Africa" by Toto, the initial strong thumping congas hits sound unnatural and overemphasized.

In conclusion, while the Tanchjim Tanya DSP may suit some listeners who enjoy strong bass experiences, its overall bass performance and tonal balance might not be as desirable for those seeking more accuracy and subtlety in their audio.

Mids (8/10)
Both male and female vocals come through as natural and transparent, making it one of the best midrange IEMs I've encountered.

Listening to female tracks like "Because You Loved Me" by Celine Dion and "Hello" by Adele, the IEM renders them beautifully, with lovely, crisp, and natural sound. There are no hints of peaks or fatigue in their voices, ensuring a pleasant listening experience.

Similarly, with male tracks such as "Lay Me Down" by Sam Smith and "When I Was Your Man" by Bruno Mars, the Tanchjim Tanya allows their high notes and pitch to shine, evoking emotions and delivering a lush, smooth, and clear performance.

One notable aspect is the forwardness of the singers, providing a sense of intimacy in their vocals. However, when it comes to presenting the distance and forwardness of instruments, the IEM falls short, giving the impression that they are on a default position without proper spatial distinction.

Nonetheless, the overall midrange performance of the Tanchjim Tanya DSP leaves a positive impression. Its ability to deliver natural, transparent vocals in both male and female tracks adds to its appeal.

Treble (6.5/10)
The treble performance of the Tanchjim Tanya DSP is satisfactory, as it can present some level of detail, but it lacks the sparkle and energy in the higher frequencies.

When listening to orchestral tracks like "Porco Rosso" and "Summer" by Joe Hisaishi, some instruments aren't well pronounced, and they seem to pass through the track without standing out, causing them to be easily missed. The resolution of this IEM doesn't meet the desired standard in this regard. However, a positive aspect is the absence of sibilance or dips in the mid and upper treble, which is a good sign, as many IEMs tend to have issues in the 5 – 5.5kHz range.

Overall, the high-frequency performance of this IEM is not particularly impressive. It shines more in the lower treble and midrange, enhancing the vocals of both male and female artists.

Imaging and Separation (5/10)
The imaging and separation of the Tanchjim Tanya DSP are mediocre. It can only identify left and right directions similar to a standard stereo setup. This IEM falls short in providing an immersive experience where you can accurately pinpoint instruments or sounds coming from various directions.

In the track "Summer" by Joe Hisaishi, despite there being hits at 7 o'clock and 2 o'clock positions, the IEM can only identify them as left and right, failing to create the illusion of a more immersive 360-degree effect. Similarly, in "Hide" by Juice WRLD, the 360-degree effect at the beginning of the track isn't presented properly, and the sound appears to travel only from left to right, lacking that immersive sensation.

Furthermore, when tested in games like Counter Strike 1.6 and Valorant, the Tanchjim Tanya DSP does showcase footsteps from left and right directions. However, its performance in providing accurate width and height information is lacking, leading to confusion for players trying to discern the precise location of enemy gunfire.

Consequently, this IEM may not be well-suited for gaming, especially in FPS games.

Soundstage (2.5/10)
The soundstage of the Tanchjim Tanya DSP is indeed lacking, as it fails to provide a sense of space and depth when listening to orchestral tracks. Everything sounds compressed, and there's no immersive experience, making it feel like the sound is confined to a small room.

This limitation in soundstage also negatively impacts its performance in both gaming and orchestral tracks. In games, the lack of an expansive soundstage can affect the sense of realism and spatial awareness, hindering the overall gaming experience. Similarly, in orchestral tracks, the compressed soundstage hampers the ability to fully appreciate the richness and complexity of the music.

Additionally, the dynamic range of this IEM is also subpar, further affecting its technical capabilities. A good dynamic range is crucial for reproducing the full spectrum of sounds, from the softest whispers to the loudest crescendos, creating a more engaging and enjoyable listening experience. Unfortunately, the Tanchjim Tanya DSP falls short in this aspect.

EQ Performance (5/10)
The EQ capabilities of this IEM are average. The main issue with this IEM is its overpowering bass, which I toned down to achieve a more balanced sound profile. Additionally, I added a little bit of sparkle at around 8800Hz to provide a nice energy boost at the top end. Please let me know how it sounds on your end in the comments below!

COMPARISON WITH OTHER IEMS
CCZ Warrior

Both the Tanchjim Tanya DSP and CCZ Warrior have heavily boosted bass and lack detail at the top end. However, the main difference between these two is that the tonality of the CCZ Warrior is a lot worse than that of the Tanya. The CCZ Warrior's tonality is warm and heavily bass boosted, causing it to sound muddy. On the other hand, the Tanchjim Tanya DSP maintains a sense of clarity and delivers good midrange performance, allowing the vocals to shine.

Having said that, I would 100% prefer the Tanchjim Tanya DSP over the Warrior.

CVJ Mei
Both similarly priced, the Tanchjim Tanya DSP significantly outperforms the CVJ Mei in terms of vocal tonality. While both models exhibit robust bass, the quality of the bass in the Tanchjim Tanya DSP surpasses that of the CVJ Mei. However, the CVJ Mei manages to slightly rebound in the Imaging and Separation category. The precise accuracy of instrument localization in my orchestral tracks sounds notably better on the CVJ Mei than on the Tanchjim Tanya DSP. The treble performance of both models is quite comparable, but the Tanchjim Tanya DSP edges ahead.

In summary, although they share similar sound characteristics, if I had to pick one, I would still favor the Tanchjim Tanya DSP for its superior tonality.

Conclusion
Priced at around $24, the Tanchjim Tanya DSP delivers one of the best vocal performances I've heard from an IEM. Its relatively affordable price makes it a solid recommendation for those who enjoy listening to vocal-focused tracks from artists like Taylor Swift, Sam Smith, Charlie Puth, and more. However, it's essential to consider that the technical capabilities of this IEM are also among the worst I've reviewed. Therefore, if you're a gamer or someone who values pinpoint accuracy in instrument reproduction, this may not be the ideal choice for you.

Again, I would like to express my gratitude to TANCHJIM for providing me with the review unit of the Tanchjim Tanya DSP. I want to clarify that all the thoughts and opinions expressed in this review are entirely my own, and I have not received any sponsorship or incentive to promote or favor this IEM in any way. It is important of me to provide an unbiased and honest assessment of the product.

Tonality (8/10) – Silicone Eartips
It managed to produce a natural and organic sound for my tracks, evoking a joy I hadn't felt in a long time. However, when using the silicone tips, the tuning sounds a bit V-shaped, meaning that the bass and treble are slightly emphasized while the mids are recessed. However, the recessed mids aren't so deep that their presence is entirely unfelt. They're still there, just a bit too recessed for my taste.

When listening to vocals, both male and female voices were beautifully represented with natural and organic tones through this IEM. Sam Smith's track "Lay Me Down" was presented perfectly and emotionally, provoking empathy for the track. The high notes are exceptionally sweet, clear, and detailed; it feels as if he's singing directly into my ears. However, in some tracks, such as "Wolves" by Selena Gomez, noticeable sibilance appears in the "Ss". As I mentioned earlier, when using the silicone tips, the bass and treble are emphasized.

Moving on, when listening to orchestral tracks, all instruments sounded as natural as they should. My favorite track, "Porco Rosso" by Joe Hisaishi, was delivered so beautifully it moved me and brought a smile to my face after a long time. Every instrument, including hi-hats, drums, trumpets, etc., was played with amazing resolution and detail. I am genuinely in awe when I listen to orchestral tracks using this IEM.

Overall, this IEM excels particularly with orchestral tracks, immersing you in the music and creating the feeling of being an audience member at a live concert.

Tonality (9/10) – Foam Eartips
When using the foam eartips with this IEM, I personally find the sound much more accurate. The use of foam eartips doesn't significantly alter the signature, but it does eliminate the V-shaped sound prevalent when using the silicone tips. Foam tips tend to mitigate both bass and treble, resulting in a more balanced and natural sound. It's important to note, however, that the reduction in bass and treble is not drastic. The most noticeable change lies in the lows, as it's evident that the sub-bass is almost gone, but the highs remain present, maintaining their level of clarity and detail.

In conclusion, if you're looking for a more lively and enjoyable sound signature, go for the silicone eartips. But if you're seeking a more natural and balanced sound signature, opt for the foam eartips. Regardless of your choice, you won't be disappointed with the tuning of this IEM.

Bass (8.5/10) – Silicone Eartrips
The bass produced by the S12 Pro is excellent, a quality that is rare to find in IEMs based on my previous reviews. When I listen to "Killing Strangers" by Marilyn Manson, the deep rumble and slam at the start of the track make my heart pound. It's so heavy and impactful that I can even feel the rumble in the IEM. The sub-bass performance of this IEM is also quite clear and distinct, making bass-heavy tracks extremely enjoyable to listen to. Moreover, genres like EDM, Hip-hop, and R&B are delightfully fun with this IEM.

When it comes to instruments such as drums, bass guitars, and congas, the S12 Pro produces a rich and natural sound that is genuinely pleasant to listen to. In the track "Serious Business" by Jazz Funk Soul, this IEM was able to render the fun and groovy drum hits that made me want to move along with the music. Another track, "School’s Out" by The Brand New Heavies, presented deep lows right at the start that kept me smiling throughout.

In terms of gaming and watching movies, this IEM could be considered overkill for the vast majority of listeners. The sounds of explosions, gunshots, and rumbles are clearly heard and add to the enjoyment of these experiences.

Overall, I have nothing but praise for the bass of the S12 Pro. However, some may find the impact of the bass a bit overwhelming, and that's where the foam eartips could come in handy.

Bass (8/10) – Foam Eartips
The foam eartips pairs really well with the S12 Pro. However, you might notice a lack of rumble and deep lows in the bass region, as foam eartips tend to lessen the impact of the bass.

When listening to "Killing Strangers" by Marilyn Manson, the track's beginning doesn't feel as intense and weighty as it does with silicone tips. Nevertheless, the quality of the bass remains unchanged. It continues to deliver clear, natural, and robust bass overall. Occasionally, with tracks like "Sunflower" by Post Malone, I find myself preferring the foam tips, as they present a more accurate bass at the start of the track. The silicone tips can sometimes overemphasize the bass, more than I typically enjoy.

In conclusion, both types of eartips will provide you with satisfaction and enjoyment in your listening experience. If you prefer more bass, go for the silicone eartips. For less bass, opt for the foam eartips.

Mids (7/10) – Silicone Eartips
The mids of the S12 Pro are commendable. With the silicone eartips, both male and female vocals are clear and well-pronounced. However, they seem slightly recessed to me. This could be because the elevated bass and treble create an illusion of the mids being recessed. Nonetheless, the IEM's performance in the midrange is quite satisfactory. When I listen to Celine Dion's "Because You Loved Me" and Michael Bolton's "When A Man Loves A Woman", the vocals sound relatively forward, but not overly so, and come across as powerful and strong. I can feel the depth in their voices and the natural high notes achieved at the height of their vocal ranges.

Mids (8/10) – Foam Eartips
Since the use of foam eartips reduces the peaks in both the bass and treble, it creates a more balanced tuning and eliminates my earlier perception of a recessed midrange. Furthermore, when using foam eartips, I experience a more natural and balanced sound. Vocals are more pronounced and genuine, without any noticeable peaks or dips. Instruments sound more “right” and authentic.

Treble (8/10) – Silicone Eartips
The treble performance of the S12 Pro provides a significant amount of detail and clarity to my listening experience. It's been a while since I've heard an IEM that offers this level of clarity for my favorite orchestral tracks. However, when using silicone tips with this IEM, it generates excessive highs that sound unnatural in tracks featuring high notes. This is evident when listening to 陆虎’s "雪落下的声音," where the singer's voice appears sibilant at certain parts of the song. Another example is "Sunflower" by Post Malone, where the "S" sounds overly emphasized.

When it comes to instrumentals, I have no complaints. They sound exactly as they should, providing an authentic listening experience. I truly appreciate the sound of this IEM when playing orchestral tracks. Despite the additional boost in both bass and treble making it sound slightly unnatural, it still manages to offer a fun and enjoyable listening experience.

Treble (8.5/10) – Foam Eartips
With foam eartips, the treble performance of this IEM seems significantly more natural. Some might perceive it as veiled, but in my personal opinion, it sounds perfectly balanced, although your mileage may vary (YMMV). The details aren't as forward and pronounced as they are with the silicone tips, but they're still audible. Moreover, the clarity of both male and female vocals appears more natural and smooth compared to the more “aggressive” sound produced by silicone tips.

Imaging and Separation (10/10)
The imaging and separation of the S12 Pro are outstanding. I could distinguish all the instruments playing in my favorite orchestral tracks, "Porco Rosso" and "Summer" by Joe Hisaishi. Each instrument is placed precisely where it should be, and in the track "I Want To Break Free" by Queen, the IEM easily handles the 360-degree electric guitar riff.

While gaming, specifically with Counter-Strike 1.6 and Valorant, I was notably impressed by the accuracy of the IEM's imaging. The sounds of enemy footsteps and gunfire can be clearly heard from left to right and front to back. I can highly recommend this IEM for competitive gamers.

Whether using silicone or foam eartips, the impact on imaging and separation is minimal. However, I would prefer using silicone eartips, as the additional treble can help players more easily pinpoint the location of their enemies' footsteps.

Soundstage (5/10)
The soundstage of the S12 Pro is average. I anticipated superior performance in this aspect from this IEM, but regrettably, the soundstage is merely satisfactory. The immersive experience and depth it provides fell short of my expectations. The perception of distance, width, and height of instruments in my orchestral tracks appears consistent, lacking the desired variation. It doesn't provide the feeling of being at a live concert when listening to these orchestral pieces.

In terms of gaming, the dynamic range of this IEM is good, creating an illusion of a good soundstage. However, I still don't sense the depth I seek. In conclusion, the immersive experience it provides is average.

EQ Performance (N/A)
For the first time in all my reviews, I don't feel the need to adjust the equalization (EQ) settings for this IEM; it already sounds exceptionally good straight out of the box. When I use foam eartips, they align perfectly with my personal sound preference, delivering the natural and well-balanced tuning I seek. However, when I'm in the mood for a more enjoyable sound signature, I switch to the silicone eartips.

Comparison with other IEMs
LETSHUOER D13

Priced at nearly $135, I find it useful to compare the S12 Pro with its lower-end counterpart, the D13. In my personal opinion, the S12 Pro outperforms the D13 in almost every aspect of the frequency spectrum, especially when you use the foam eartips. It excels in tonality and performs exceptionally well with orchestral tracks. However, the S12 Pro doesn't match the D13 in terms of technical capabilities. Therefore, if technical performance is your priority, the D13 would be the better choice. But, if that's not a key concern, I believe that the additional $35 to upgrade to the S12 Pro is well worth it.
TANGZU x HBB Wu Heyday Edition
Priced at approximately $135, the S12 Pro's sole competitor in my experience is the TANGZU x HBB Wu Heyday Edition, which retails around $200. From memory, I find myself gravitating towards the S12 Pro, which, to my ears, performs significantly better in my favored genre, orchestral music. The technical prowess of the S12 Pro may not rival that of the Heyday Edition, but in my opinion, its tonality surpasses the latter.

Given its more affordable price tag of just $135, I would opt for the S12 Pro over its competitor.

Conclusion
For a price tag of around $135, I wholeheartedly recommend this IEM to anyone who wishes to experience the magic of orchestral music. It's an overall well-rounded IEM that can suit a wide range of sound preferences. Furthermore, the inclusion of both foam and silicone tips is extremely useful for those who wish to alter the sound output.

This IEM also brings back memories of my first encounter with the Hifiman Arya Stealth. Both audio devices brought a smile to my face and kindled a desire to listen to more orchestral and instrumental tracks. The natural and organic reproduction of both vocals and instruments enables me to enjoy listening for hours on end. Great job, Letshuoer team!

The Letshuoer D13 includes a silver nozzle and gold nozzle, which I tested extensively prior to writing this review. There is a difference between the two nozzles. However, I will only review the silver nozzle as for me it sounds more natural and less aggressive than the gold nozzle. Moreover, I will still provide a short comparison between the silver and gold in each category. The ratings however, will be based on the silver nozzle only.
As for the eartips, I used the default large silicone eartips and stock cables that is included in the packaging.

Tonality (7.5/10)
When utilizing the silver nozzle, the tonality of the D13 is quite satisfactory. It delivers a smooth and non-fatiguing sound. However, I perceive it as lacking clarity and detail in the higher ranges. Its midrange performance is its strongest point, providing an intimate and natural timbre for both male and female vocalists.

Regarding instrumental reproduction, the D13 manages to present details adequately. Nevertheless, it lacks vitality and sparkle in the higher frequencies, causing it to sound somewhat veiled and unnatural. I don't find this to be a significant issue as the tuning of this IEM leans towards the smoother/warmer side, with a focus on mids and bass.

When the gold nozzle is in use, the tonality of the D13 alters slightly, particularly in the treble range. The most notable shifts occur in both the 2kHz range and the 5-6kHz area, resulting in an annoying and irritating sound, especially when listening to sibilance-prone music such as "Wolves" by Selena Gomez. Consequently, vocals tend to sound somewhat more nasally.

Orchestral tracks benefit slightly from the added "detail" introduced by the gold nozzle. However, I would still favor the silver nozzle, as it delivers a more natural sound overall. The gold nozzle slightly elevates the mid-treble to upper-mid treble, which doesn't adequately address the veiled aspect of the IEM.

In conclusion, I would recommend users to opt for the silver nozzle, as it produces a more natural and smooth sound. Conversely, the gold nozzle introduces peaks that, instead of remedying the problem, create more issues.

Bass (7/10)
The bass performance of the D13 is impressive, boasting high-quality and impactful bass. Upon listening to "Killing Strangers" by Marilyn Manson, the track's beginning comes in heavily, with the subbass audibly resonating throughout. Another exemplary piece is "School's Out" by The Brand New Heavies, where the deep-reaching bass guitar at the start is cleanly reproduced by the D13, devoid of distortion.

When it comes to drums and other acoustic instruments, the D13 capably renders high-quality, thumping bass, as well as profound rumbles. AC/DC's "You Shook Me All Night Long" serves as my standard test for drums, and this IEM delivers consistently good bass quality throughout the track. In addition, when listening to genres such as EDM, Hip-hop, and R&B, the D13's bass performance can occasionally be dominant, but it remains immensely fun and enjoyable.

Upon employing the gold nozzle, I didn’t detect any notable differences in the bass region. If there were any, they are likely too subtle to be perceived by most listeners.

In conclusion, the D13's bass performance warrants nothing but commendation. That said, my personal preference would be to introduce a -1dB low shelf filter at around 350hz, as the bass can occasionally overshadow the track's treble component.

Mids (7.5/10)
The midrange performance of the D13 is quite impressive. For me, it's a standout feature of this IEM. Vocals are notably emphasized in this range, delivering a richness and smoothness simultaneously.

Listening to male vocal tracks like "When a Man Loves a Woman" by Michael Bolton, his voice is portrayed as full-bodied and robust throughout the track. It also feels natural and emotionally resonant, allowing me to fully immerse myself in the song. The vocals are smooth, warm, and soothing. All I can say is that this IEM performs exceptionally well with male vocals.

Shifting focus to female vocals, such as in the track "Unconditionally" by Katy Perry, I found that her voice lacks the resolution I usually detect with my other IEMs. It sounds a tad too warm for my preference. However, it still manages to produce natural and organic sounding vocals. Another song, "Love Me Like You Do" by Ellie Goulding, features her voice as smooth and non-fatiguing throughout, making it a pleasing listen. However, if you prioritize high-detail and brilliant "female" vocal performance, this IEM may not fully meet those expectations.

In conclusion, this IEM delivers smooth and rich vocals for both male and female artists. However, it tends to favor male vocals a bit more effectively.

Treble (5.5/10)
The treble performance of the D13 is mediocre. It definitely falls short in terms of clarity and resolution. This is further exacerbated when using the gold nozzle, as it induces an artificial boost in the mid-treble range.

When listening to "Come Together" by The Beatles, the opening hi-hat hit lacks the desired clarity. It appears muffled and lacks the requisite presence. Similarly, in "Enter Sandman" by Metallica, the instruments are discernible, but lack the airiness and resolution that I typically prefer.

However, it's not all negative in this aspect. When it comes to tracks that lean more towards the sibilant or higher frequency range, this IEM effectively mitigates the issue. A case in point is "For Whom The Bell Tolls (Remastered)" by Metallica. The song sounds warm, rich, and non-fatiguing with each instrument being played, thus enhancing the overall listening pleasure.

But if you're after detail, clarity, and resolution, I would recommend considering the Letshuoer S12 Pro instead.

Imaging and Separation (8/10)
The imaging and separation capabilities of the D13 are impressive. It accurately presents instruments across the soundstage from left to right.

Listening to orchestral tracks like “Porco Rosso” and “Summer” by Joe Hisaishi, all instruments were well positioned with precision, enabling me to distinguish them with ease. Furthermore, in the track “Hide” by Juice WRLD, the IEM could effectively create the 360-degree effect I was seeking at the start of the track, enhancing my sense of immersion. I experienced similar effects with “I Want To Break Free” by Queen, where the introduction's electric guitar part achieved a 360-degree effect without effort.

In addition to music, I also tested this IEM with games like Counter Strike 1.6 and Valorant. I was able to easily detect the footsteps of both enemies and teammates. The sound of gunfire was clearly identifiable from left to right, which left me thoroughly impressed.

Soundstage (7.5/10)
The soundstage of the D13 is indeed commendable. I was pleasantly surprised by its performance with orchestral tracks, particularly in terms of the depth and distance of the instruments being played. It effectively conveys the expansive ambience of the concert space.

While listening to "Hotel California" by the Eagles from the album "Hell Freezes Over", I could discern the spaciousness and depth of the area where the instruments were played. The dynamic range of this IEM also contributes to the soundstage, as lowering the volume tends to result in the instruments sounding more distant. This is especially noticeable with orchestral tracks.

When using this IEM with FPS games such as Counter Strike 1.6 and Valorant, the distance of the gunshots is convincingly portrayed. I would recommend this IEM to competitive gamers who prefer using IEMs as their primary audio device.

In conclusion, the soundstage of the D13 is impressive and immersive, a quality many IEMs fail to deliver, making it truly one of a kind.

EQ Performance (7/10)
The equalization (EQ) capabilities of the D13 are fairly good. I was able to tweak them to my sound preference effectively. The primary changes I made were reducing the 4500hz and adding a high shelf from 5000hz onwards to lend the sound more vibrancy and energy in the upper range. I also toned down the 6000hz frequency as it came across as slightly sibilant to my ears. The other adjustments I made were more minor. Please try out my EQ settings and share your experiences in the comments below.

Comparison with other IEMs
LETSHUOER S12 Pro

Priced at nearly $100, I find it useful to compare the D13 with its higher-end counterpart, the S12 Pro. In my personal opinion, the S12 Pro outperforms the D13 in almost every aspect of the frequency spectrum, especially when you use the foam eartips. It excels in tonality and performs exceptionally well with orchestral tracks. However, the S12 Pro doesn't match the D13 in terms of technical capabilities. Therefore, if technical performance is your priority, the D13 would be the better choice. But, if that's not a key concern, I believe that the additional $35 to upgrade to the S12 Pro is well worth it.

BGVP DN3
Priced around $75, the BGVP DN3's out-of-the-box sound isn't technically as proficient as the D13's. However, when equalized, the DN3 can realize its full potential, delivering a sound quality that rivals even more expensive IEMs. Nonetheless, it falls short of the D13 in terms of technical capabilities.

Without equalization, the vocals produced by the DN3 can sound a bit too forward and nasal, whereas the D13 offers a more balanced presentation. In terms of overall tonality without EQ, the D13 surpasses the DN3. But when EQ comes into play, I would recommend giving the DN3 a try, as it outshines the D13. The DN3's capabilities when equalized are truly exceptional.

Conclusion
The Letshuoer D13 delivers a warm, rich, and smooth sound that is non-fatiguing to listeners. Priced around $100, I would specifically recommend this IEM to those who favor a warmer sound signature and enjoy gaming and watching movies.

However, if you're a listener who appreciates detail, resolution, transparency, and clarity, I would strongly suggest checking out the Letshuoer S12 Pro. Despite its higher asking price of around $135, the enhanced audio experience it offers makes it a worthwhile upgrade.

361921941_237385815853258_5660729578975490355_n.jpg


Tonality (8/10)
The tonality of the EW100P is great. They offer a well-balanced sound signature, although they lean slightly warm for my personal preferences. While the sound is technically well-tuned, it doesn't quite deliver the natural and organic sound one might expect. Let me compare them directly to my reference earbuds, the NiceHCK EB2S Pro. Both have a similar tuning, but the EW100P is bassier and overall warmer sounding. The vocals of both male and female tracks on the EW100P are well-balanced and well-tuned, but they lack the emotions and natural quality found in the EB2S Pro.

When listening to tracks like "Lay Me Down" by Sam Smith or "Immortality" by Celine Dion, the vocals are good, but they sound dull and fail to provide that immersive and emotional experience in their voice. One of my favorite male tracks is Michael Bolton's "When a Man Loves a Woman." His voice doesn't sound impactful or strong. The depth in his voice is not present in that track at all. Additionally, with Lady Gaga's "Always Remember Us This Way," I also experienced the same result.
Moving on to instruments, the EW100P was able to maintain good detail and tonality in the instruments played in orchestral tracks. My favorite tracks from Joe Hisaishi, "Porco Rosso" and "Summer," both delivered really good tonality. However, they fell short in evoking strong emotions or delivering that "wow" factor.

Overall, the EW100P showcases solid technical tonal tuning, but its overall sound can be described as somewhat dull and lacking excitement. It doesn't bring anything special to the table. But as mentioned in the pros of these in-ear monitors (IEMs), they are "a jack of all trades, but master of none."
Bass (7.5/10)
The bass of the EW100P earphones is impressive. It consistently delivers good-quality bass during my listening sessions. The sub-bass and rumble are also noticeable in my test tracks. However, at times, it tends to obscure the sound of my tracks, resulting in a warmer sound signature.
One of my favorite tracks to test the sub-bass and rumble is Marilyn Manson’s “Killing Strangers”. It effectively reproduces the deep lows at the beginning of the track, and I thoroughly enjoyed every moment. Another track that stands out is “Flirting with Jane” by Les Gordon. The bass remains consistently good and smooth across all my bass-heavy tracks. It produces a strong, punchy, and wide slam effect.

However, when listening to drum hits or any organic instruments that are associated with the bass, such as the track “Serious Business” by Jazz Funk Soul and “Hotel California” from the album “Hell Freezes Over” by Eagles, the IEMs fall short in delivering the natural and organic tones of the drums and congas. It doesn't quite capture the essence of these instruments accurately.

For movies and gaming, the bass performs well, allowing me to enjoy the impact of explosions and other intense moments.

Overall, the bass quality of the EW100P is good, consistently delivering decent bass performance during my testing. However, one major flaw is that it fails to provide the organic and natural sound that I am seeking.

Mids (5.5/10)
The mid-range performance of the EW100P is average. The lower mids, in particular, pose an issue. They are slightly elevated for my preference, resulting in additional honkiness and warmth in the sound. Additionally, the upper mids' performance is not as impressive as I had anticipated. It fails to reproduce the intimate vocals in my tracks. There seems to be a noticeable distance between me and the singer, leading to a recessed sound signature in the upper mids. This becomes evident in songs like "When a Man Loves a Woman" by Michael Bolton and Celine Dion's "Because You Loved Me". Furthermore, the tone of their voices lacks naturalness and lacks impact and presence. While there is some clarity, the overall sound tends to be artificial and slightly too warm for my personal preference.

Treble (7/10)

The treble performance of the EW100P is decent. It provides the clarity and detail that one would expect from a good in-ear monitor (IEM). However, as mentioned earlier, the detail and clarity don't sound natural or authentic. It feels like they are being forced and don't come across as genuine. Nevertheless, one commendable aspect of this IEM is the absence of the typical 5000 - 5500Hz peak that often annoys me. In that regard, I can say that it sounds quite pleasant and smooth, albeit still sounding somewhat artificial and lacking vibrancy.

Furthermore, the extension and airiness of this IEM are lacking, especially in the 9300Hz range. It requires more energy in the higher frequencies for me to fully enjoy the level of clarity in my tracks.

When listening to orchestral tracks such as "Porco Rosso," "Summer," and "Departure -memory-" by Joe Hisaishi, the IEM is able to maintain a nice tonality throughout the track. However, it fails to capture the authenticity and sparkle that I was hoping for. The sound comes across as somewhat dull and fails to evoke any strong emotional response, leaving one feeling indifferent, thinking, "It's alright."

Imaging and Separation (7.5/10)
The imaging and separation of the EW100P are impressive. It effectively identifies instruments coming from the left and right channels. For instance, when listening to "Hide" by Juice WRLD, the beginning of the track creates a 360-degree sound effect, and the IEM is able to recreate it, although not flawlessly. Similarly, in the track "I Want To Break Free" by Queen, the electric guitar part at the start of the track also exhibits a 360-degree sound effect, which the IEM manages to produce, but still with some room for improvement.

As for the dynamic range, it is only average and fails to reach an exceptional level. However, when listening to orchestral tracks, the positioning of the instruments is accurately represented, each occupying their rightful place.

In terms of gaming, specifically playing games like Counter Strike 1.6 and Valorant, the EW100P performs well. It effectively renders the footsteps and shooting sounds from enemies, allowing for precise localization. It enables me to quickly determine the direction from which a shot was fired.

Soundstage (5/10)
The soundstage of the EW100P is average. While it offers good imaging, the sense of distance between instruments in orchestral tracks is not as immersive as I had anticipated. It lacks the expansive and enveloping feeling that I would expect from a more impressive soundstage. When listening to a concert recording, the height and width of the stage don't give me the sensation of being in a large venue; instead, it feels more like I'm confined to a small room.

Moreover, when using the earphones for FPS games, the distance between enemy footsteps is acceptable. However, the dynamic range of the IEM hampers its performance in this category, causing it to fall short of delivering a truly immersive and engaging gaming experience.

EQ Performance (7/10)
The EQ performance of the EW100P is commendable. I was able to achieve the sound I desired with minimal EQ adjustments. Upon reviewing the information on the back of the IEM's box, I discovered that it is specifically tuned to the Harman 2016 target. This explains why I felt little need for extensive adjustments. The main changes I made involved reducing the lower mids and bass while increasing the energy around 9300Hz to add sparkle to the music.

Overall, the sound quality was satisfying to me. However, I must note that the natural and organic sound I seek still eluded me. I invite you to share your thoughts on my EQ adjustments for this IEM in the comment section below.

Conclusion
The SIMGOT EW100P is an excellent all-rounder that caters to individuals in search of a versatile IEM that can handle various tasks without significant issues. As I mentioned in the pros, it can be seen as a Jack of all trades, but a master of none. While it may not excel in areas such as soundstage and dynamic range, it still delivers a commendable sonic performance that makes it a reliable recommendation for the average consumer.

Priced at only $20, this IEM is a safe choice, particularly for those who are new to the hobby and prefer not to invest a substantial amount of money upfront. However, it's important to keep in mind the mentioned cons when considering this option.

Overall, the SIMGOT EW100P offers a well-rounded experience and represents a solid choice for individuals seeking an affordable and versatile IEM that performs capably in various scenarios.

P.S.

Again, I would like to express my gratitude to LINSOUL and Sir @Zerstorer_GOhren for providing me with the review unit of the SIMGOT EW100P.

Tonality (9/10) – This category holds utmost significance when it comes to audio gear. Moreover, it can serve as a succinct summary of the product.
The tonality of the NiceHCK EB2S Pro is exceptional. I am genuinely astounded by the quality of these inexpensive earbuds. They deliver a natural, organic, and authentic tone in both vocals and instruments that is second to none. I struggle to find words that adequately express their superb sound quality. The instruments in my favorite track, “Porco Rosso” by Joe Hisaishi, are rendered so brilliantly that it brought tears to my eyes, particularly during the trumpet sequences. Furthermore, Calum Scott’s “No Matter What” sounded so natural and authentic that it left me stunned and in awe.

I believe further explanation is unnecessary regarding the remarkable sound these earbuds deliver. I encourage you to try them yourself; you won't be disappointed.

Bass (4/10)
The bass of the NiceHCK EB2S Pro is almost imperceptible. It's incredibly light and lacks significant impact. However, that does not necessarily detract from the enjoyment it provides. It bears similarity to the HD600, albeit even lighter. Personally, I find it quite satisfactory, provided it isn't a hollow, cheap bass. And fortunately, the bass from these earbuds doesn't fall into that category. When listening to tracks like "Circles" and "Mourning" by Post Malone, you might expect a heavy bass to hit your ears at the start, but these earbuds don't provide that kind of experience; instead, it's a gentle thump. The same applies to other tracks such as "Killing Strangers" by Marilyn Manson and "You Shook Me All Night Long" by AC/DC. So, if you're a bass enthusiast, these earbuds might not meet your expectations.

Mids (9/10):
The midrange of the NiceHCK EB2S Pro aligns closely with that of the HD600. It's pronounced, but not overly so, which is a balance I find excellent. These earbuds exhibit a well-balanced tuning between mids and treble, avoiding nasal or overly sharp tones. Male vocals sound authentically male, and female vocals maintain their distinctive female quality. While listening to "T.N.T" by AC/DC, Brian Johnson's voice is so finely detailed and natural that these earbuds could feasibly rival IEMs priced at $100 or even $200.

Furthermore, when tuned to female vocals such as Celine Dion's "Immortality," these earbuds accurately reproduce her soaring high notes and the potent strength of her voice.

Treble (9/10)
The treble of the NiceHCK EB2S Pro possesses an engaging energy that enhances song detail without sounding overly bright or inducing listener fatigue. When listening to "Summer" by Joe Hisaishi, I can discern each instrument's sound from every direction. The detail this earbud provides is exceptionally good. Furthermore, its treble extension is impressive, exhibiting the delicate hi-hat taps in the opening of Metallica's track "Enter Sandman" with superb clarity. However, it is not flawless, with a slightly annoying peak noticeable at around 5.5 kHz. I found this a minor distraction, but your experience may differ.

Imaging and Separation (10/10)
The imaging and separation of the NiceHCK EB2S Pro are impeccable. While listening to "I Want to Break Free" by Queen, the 360-degree sound of the electric guitar intro was so realistic that it transported me, making me feel as though I was at their concert. Similarly, with Joe Hisaishi's orchestral track "Porco Rosso," the instruments seemed to occupy every inch of the concert hall. I found myself almost able to pinpoint each one. I'm at a loss for words to fully express the superior imaging and separation these earbuds offer.

Soundstage (6/10)
The soundstage of the NiceHCK EB2S Pro is respectable. In the song "Porco Rosso" by Joe Hisaishi, it effectively presents the separation between instruments, although determining the precise distances proves challenging. While it's commendable, it doesn't quite measure up to headphones like the Hifiman Arya or HD800s. Nonetheless, it's a notable improvement over the BGVP DN3, which I reviewed previously. In addition, I tested these earbuds for gaming, assessing their capability to distinguish the distances between the sounds of enemy and teammate footsteps. They managed to create a subtle soundstage, but it was nothing so remarkable as to earn special praise.

EQ Performance (5/10)
The EQ performance of the NiceHCK EB2S Pro is average; it doesn't respond exceptionally well to EQ adjustments. However, the exceptional sound quality of these earbuds makes such adjustments largely unnecessary. I'm just splitting hairs here, trying to tweak the sound to better align with my personal preferences. I primarily added a low shelf filter and a slight dip in the 5500hz region. Any other adjustments to frequencies are merely minor tweaks. Feel free to disregard them if you wish. I'd love to hear your thoughts on my EQ adjustments in the comments below.

Conclusion:
The NiceHCK EB2S Pro is an earbud I purchased out of curiosity after watching DMS's "Ultra Budget Earbud Roundup!" video. And YES, I can confidently say that for its price, the sound quality is outstanding—almost perfect, in fact. I highly recommend it to anyone seeking a quality earbud under $20. Please bear in mind, however, that these may not appeal to bass enthusiasts. But for those pursuing high fidelity sound, these earbuds are simply perfect.

P.S.
This will now serve as my new benchmark for earbuds. While I have yet to find an equivalent among IEMs, I will frequently use these earbuds as a point of comparison with other IEMs.


Again, this unit was purchased with my own money, and my reviews will always remain honest and unbiased, whether the items are self-funded or sponsored. Thank you once again for reading my review. Have a great day!
Question2
Question2
@4ceratops : Ive heard from others, the pro sounds much better and warmer.

I have to say the review is pretty much spot on, i can hear an impressive amount of detail and it does sound similar to the yuin pk2 and ksearphone lbbs. The problem im having is that the fit is quite bad, at least for me. It might be that the drivers are slightly bigger (15.4mm) or the shape of the shell, but i can feel the earbuds and they feel like they are blocking up my ear. Its a very distracting feeling. I think i have smaller ears than on average though, so it might not be the earphone's fault.

I do think my pk2s sound better though, although im not sure if they are real pk2s or have been damaged as they are a very old pair. they are the "new" version with the gray logo (the original uses white). one thing i noticed when doing a comparison is that the PK2s sound much "louder" at the same volume, especially with stuff like drums.

I have the 4.4 balanced version and I'm wondering if there is a difference(even slight) in sound quality compared to the 3.5mm version. To describe it in the simplest way is, it is a very fun sounding earbuds(for me) and it easily suits any genre you throw at it. It is neutral sounding with warmth in it, the perfect sound signature for me. It has the cleanest mids I've ever heard from an earbud. It has quick punchy bass with sparkly treble. I use it(with stock foam pads) with my sony walkman zx300(which is a warm sounding DAP) paired with my ifi hip-dac 2(with X-bass on) and it sounds so good.

@Chooey choy I would agree that this is one of the best tuned earbuds for the price :)

CCZ Warrior - A Review By Zeng
360068289_964523771464334_3175760464842510578_n.jpg

359343674_1669603673518483_6874531107525942443_n.jpg

Tonality (7/10) – This category holds utmost significance when it comes to audio gear. Moreover, it can serve as a succinct summary of the product.
The tonality of the CCZ Warrior is impressive, as it delivers a warm and bassy yet neutral sound signature. It effectively reproduces the warm and natural vocals of both male and female singers. In Celine Dion's "Because You Loved Me," her vocals are smooth and pleasing, allowing me to enjoy the entire song without being distracted by the powerful bass. Similarly, in Bruno Mars' "When I Was Your Man," his voice sounds rich, engaging, and exhibits a well-balanced treble presentation. Another track that I particularly enjoy is Michael Bolton's "When a Man Loves a Woman," where his strong and impactful voice brings the song to life, making it lively and enjoyable.

When it comes to instrumental tracks such as Joe Hisaishi's "Porco Rosso," "Summer," and "Departures -memory-," I find them to be quite satisfying. The warmth and lushness of the sound create a soothing and non-fatiguing listening experience, especially when it comes to hi-hats and cymbals. However, due to its warm sound signature, there are instances where I feel the lack of energy in the upper frequencies for instrument details. Nevertheless, this IEM provides an enjoyable and addictive sound overall.

Furthermore, when listening to genres like rock and EDM, I must say that the CCZ Warrior performs admirably. In tracks like AC/DC's "Shoot to Thrill," "You Shook Me All Night Long," and "Shot In The Dark," the drums tend to be overly emphasized, which can be a drawback. On the other hand, EDM tracks like "Faded" and "Siren Screen" by Ooyy offer an enjoyable and fun experience with emphasized bass sections that make you want to groove along. The IEM truly shines when playing "Boss Mode" by Knife Party.

Bass (7.5/10)
The bass response of the CCZ Warrior is exceptional and undoubtedly the standout feature of this IEM. It imparts a warm, lush, and smooth character to the overall tonality. While it may not align perfectly with my personal sound preferences, I must admit that the strong bass has its merits, particularly when it comes to enjoying EDM, movies, and gaming. The immersive and addictive quality it brings to these experiences is undeniable. For those who prioritize bass and consider themselves bass enthusiasts, the CCZ Warrior is a definite keeper. It excels in this category and will undoubtedly serve you well.

Mids (4/10)
The midrange performance of the CCZ Warrior is subpar. It possesses the typical V-shaped sound but doesn’t affect much on the treble side. The main issue here, however, lies within the dips in the midrange. The excessive bass compromises the midrange, resulting in a muddy and recessed sound. Despite this, the vocals manage to retain a natural and rich quality, although their presence is noticeably lacking. If you're a fan of the mids in the HD600, you'll find that the CCZ Warrior offers quite the opposite experience.

Treble (5/10)
The treble performance of the CCZ Warrior is mediocre. While it manages to deliver detailed, non-fatiguing, and smooth treble that contributes to an engaging listening experience, the clarity of the detail falls short. Although you can hear the instruments, they lack a certain quality. This becomes particularly noticeable when listening to orchestral tracks like "Porco Rosso" and "Summer" by Joe Hisaishi. Despite the sound being present, it lacks the intricacy one might expect. The treble of the CCZ Warrior echoes the HZSOUND Heart Mirror Pro in that both miss the mark when it comes to providing the energy and sparkle in the upper treble.

Imaging and Separation (6/10)
The imaging and separation performance of the CCZ Warrior is decent. It can effectively distinguish sounds from the left and right, though not quite as well as the Heart Mirror Pro. Its performance is more akin to a stereo system rather than headphones. When listening to "Porco Rosso" by Joe Hisaishi, the instruments seem to play merely from the left or the right. Unlike a compass direction, where one could specify upper left, upper right, etc., the spatial distinctions aren't as nuanced here. During gameplay, its performance falls short of the Heart Mirror Pro, with auditory directions mostly limited to what one might liken to the 9 o'clock and 3 o'clock positions.

Soundstage (3/10)
The soundstage of the CCZ Warrior leaves much to be desired. A prime example of this is its performance during gaming. The sound of distant enemy footsteps doesn't carry the expected sense of remoteness. The sounds of my footsteps and those of my teammates seem to blend together, causing confusion about whether it's an enemy or a teammate approaching.

Listening to orchestral tracks, like “Porco Rosso” by Joe Hisaishi, further highlights this issue. The relative distances of different instruments, such as trumpets and hi-hats, are inaccurately represented, sounding as if they're at the same distance, which is not the case in reality. There's a distinct lack of height and depth to the sound, making it feel more like listening to a radio than an immersive IEM.

In summary, if you're seeking an IEM with strong technical capabilities, the CCZ Warrior may not be the right choice for you.

EQ Performance (6.5/10) - It's important to note that my EQ presets are specifically tailored to my preferred sound signature. They are not a one-size-fits-all solution.
The EQ capabilities of the CCZ Warrior is decent. I managed to tailor it to my sound preferences, though its responsiveness isn't on par with the Heart Mirror Pro or the BGVP DN3. One resolution was to reduce around 3dB of low shelf mid midrange at approximately 450Hz and add some sparkle at around 8500Hz on the high shelf for more energy in the higher frequencies. Overall, the sound quality was reasonably good, but it did not match the excellence of the previously mentioned IEMs.


361179561_3451040601893163_8871713395561780258_n.jpg


Conclusion
At around $35, I would specifically recommend the CCZ Warrior to those who favor bass-heavy IEMs and those in search of an enjoyable sound for their music. This IEM is ideally suited to genres like EDM, Pop, and Hip-Hop. It also proves adequate for movies and casual gaming, though it falls short for competitive gaming.

However, if your preference leans towards an IEM that offers quality midrange and treble, the CCZ Warrior likely won't meet your expectations. In that case, you would be better served by options like the CVJ Mei or the HZSOUND Heart Mirror Pro.


P.S.
Again, I extend my heartfelt gratitude to

HZSOUND Heart Mirror Pro - A Review By Zeng
First and foremost, I would like to say that I am truly fascinated by the packaging and accessories that accompanied the IEM. They exude a sense of premium quality and excellent craftsmanship that has left me in awe. The minimalist design and the overall presentation are outstanding.

Notes before the review
The eartips that I use are the large size silicone eartips which fit perfectly in my ear and have no background noise and have perfect isolation. Moreover, I use the 3.5mm jack for this review.


Tonality (7/10)
The tonality of the HZSOUND Heart Mirror Pro is commendable. On orchestral tracks, it accurately presents instruments with a natural timbre. The piano, trumpets, violins, and more from tracks like "Innocent," "Porco Rosso," "Nostalgia," "Summer" by Joe Hisaishi, and "Early Summer Rain" by Yasuharu Takanashi exhibit an organic and natural presentation. The music sounds lush, creamy, and rich. However, when listening to drums in AC/DC tracks such as "You Shook Me All Night Long," "Shoot To Thrill," and "Back in Black," the drum slap lacks naturalness. It seems that the middle treble is boosted, resulting in irritating peaks and unnecessary sparkle in the music.

Moving on to vocals, male vocals deliver a rich, engaging, and impactful voice in their tracks. However, there are still some peaks in the middle treble around 3kHz to 5kHz, which can be bothersome at times. Tracks like "Someone You Loved" by Lewis Capaldi and Michael Bolton's "When a Man Loves a Woman" showcase the strength and impact of male vocals in their songs. Overall, the IEM performs well with male vocals, except for instances where the middle treble can be annoying in tracks involving male singers with higher notes, such as Sam Smith, Charlie Puth, and Freddie Mercury.

On the other hand, female vocals still maintain a natural timbre in their voices, although not as effectively as male vocals due to the peaks in the middle treble. For example, in the track "Love Me Like You Do" by Ellie Goulding, her voice is clearly boosted on higher notes, and the airy quality on top can be fatiguing during prolonged listening. However, tracks by Celine Dion, such as "Because You Loved Me," "Immortality," and "My Heart Will Go On," successfully convey a natural timbre and engaging tone in her voice.

Overall, the tonality of this IEM is quite good, with only occasional instances of annoying peaks in the middle treble.

Bass (6.5/10) – Sorry I can’t give a full 7 nor a 6. Just in the middle of it.
The bass in the Heart Mirror Pro is decent, but it tends to be excessively boosted in the upper bass, resulting in a bloated sound. I often use songs like 'Sunflower' and 'Circles' by Post Malone to test bass, and at the beginning of both tracks, it's evident that the bass is overly emphasized, affecting the clarity of the mid and treble frequencies. While the bass quality is satisfactory, it doesn't offer anything exceptional.

However, if you're someone who enjoys strong bass and immersive rumble effects in gaming, movies, or EDM tracks ('Boss Mode' by Knife Party anyone?), these IEM can definitely be beneficial.

Mids (7/10)
The midrange of the Heart Mirror Pro is good. It effectively showcases a balanced blend of forwardness and distance. When listening to orchestral tracks, it accurately reproduces natural timbre, capturing the essence of the instruments. Moreover, when it comes to male and female vocals, both are rendered with authenticity and naturalness. However, it's worth noting that certain tracks with peaks in the middle treble range might exhibit occasional, bothersome boosted highs that can affect both male and female vocals.

Treble (6/10)
The treble performance of the Heart Mirror Pro is satisfactory. Let me clarify that it successfully reproduces the intricate details in my favorite orchestral track, 'Porco Rosso' by Joe Hisaishi. However, the treble can sound artificial and forced, not in terms of instrument sound but in the presentation of detail itself. The main concern lies in the mid-treble region, which can be quite bothersome when listening to tracks that feature cymbals or higher notes.

Furthermore, this IEM lacks the desired energy and sparkle in its upper frequencies, which personally disappoints me. I prefer a more vibrant and energetic sound signature.

Imaging and Separation (9/10)
The imaging and separation on the Heart Mirror Pro earphones are excellent. I could distinctly identify every instrument being played, from left to right. The track "Left and Right" by Charlie Puth, for instance, demonstrates their strong imaging capabilities. Furthermore, I tested them with orchestral tracks such as "Porco Rosso" and "Summer" by Joe Hisaishi, and they effortlessly pinpointed the placement of each instrument. I ventured into gaming with these in-ear monitors as well, trying out Counter Strike 1.6 and Valorant. To my surprise, the imaging was excellent, exceeding my expectations.

Soundstage (7/10)
The soundstage of the Heart Mirror Pro is surprisingly impressive. The spacing between each instrument in Joe Hisaishi's tracks feels accurately represented. It's as if I can sense the openness of the concert hall where the performance is taking place - almost like I'm sitting in the front row. While I don't usually commend in-ear monitors for their soundstage, as they often struggle to reproduce it as accurately as over-ear headphones, the Heart Mirror Pro has genuinely impressed me. Kudos to the makers!

EQ Performance (9/10) - It's important to note that my EQ presets are specifically tailored to my preferred sound signature. They are not a one-size-fits-all solution.
The EQ performance of the Heart Mirror Pro is outstanding! It reminded me of the last time I fine-tuned the BGVP DN3 to its utmost performance, which was fantastic. The triumph I achieved with this IEM is quite surprising, and I can't praise it enough, even compared to the BGVP DN3. I was able to seamlessly tailor it to my preferred sound signature, and it responded flawlessly without any hitches. I would love to hear your thoughts on my EQ adjustments for the Heart Mirror Pro, so please feel free to share your opinions in the comments below.

361074029_781528690120309_3838818637428544698_n.jpg


Conclusion
The HZSOUND Heart Mirror Pro is akin to a prodigious student that hides his talent in class. When called upon to perform, it delivers high-fidelity sound that leaves me deeply impressed. This IEM renders an organic, natural, engaging, and enjoyable listening experience regardless of the music genre you pair it with. However, do be mindful that without proper EQ adjustments, the mid-treble can be somewhat grating, and the bass may occasionally overpower. Yet, with the right EQ settings, it has the potential to truly shine.

At approximately $80, I wholeheartedly recommend the Heart Mirror Pro to anyone seeking a more enjoyable, natural auditory experience. Once fine-tuned with the EQ, it ascends to an entirely new level of audio performance.

CVJ Mei - A Review by Zeng

I will be giving a rating for each category of out of 10. (10 being the highest, 1 being the lowest)
356431749_628135705945432_8531986724973558636_n.jpg

360081128_1388668705037395_2194521078235902058_n.jpg


Tonality (6/10):
The tonality of the CVJ Mei is good; it is well-tuned and well-balanced. However, it sounds somewhat unnatural in the treble region, especially when listening to female vocals. Celine Dion's voice in the song "Immortality" sounds sharp and not true to life.

On the other hand, when listening to male vocals, it sounds good. Michael Bolton's voice in the song "When a Man Loves a Woman" is strong and impactful. The IEM seems biased towards male singers rather than females.

Instruments on orchestral tracks such as Porco Rosso and Summer by Joe Hisaishi sound decent. The trumpets are well presented, and the soft hits of the hi-hats are also decent. However, they still sound somewhat artificial. The drums in the song "Everything I Do (I Do It For You) [Classic Version]" by Bryan Adams sound too boomy. The upper bass appears to be elevated, overshadowing the song and creating a muddy sound.

Bass (6/10)
The bass of the CVJ Mei is decent, providing a good rumble in the subbass and enhancing the enjoyment of hip hop and R&B tracks. However, the quality of the bass is not top-notch. I find it produces a mediocre bass quality. When listening to "Killing Strangers" by Marilyn Manson, it reproduces the bass adequately but without any exceptional qualities. In short, it gets the job done but lacks premium quality.

Mids (7/10)
The mids of the CVJ Mei are good, exhibiting a well-balanced blend of forwardness and distance. They are well-tuned, although there is a slight elevation in the lower midrange that can make it sound slightly muddy. Aside from that, the mids are fairly decent.

Treble (4/10)
The treble of the CVJ Mei is subpar. It offers energy, but nothing too impressive. Similar to the bass, it sounds artificial and somewhat cheap or unnatural. Once again, it fulfills its purpose, but the quality is not high. When listening to "Porco Rosso" by Joe Hisaishi, I can discern the instruments being played and the detail is there, but it lacks authenticity. Additionally, there are no signs of harshness that can be heard through this IEM. However, prolonged listening sessions with this IEM can cause ear fatigue.

Imaging and Separation (8/10)
The imaging and separation of the CVJ Mei are actually quite good. I can easily distinguish instruments as if using a compass. When listening to both "Summer" and "Porco Rosso" by Joe Hisaishi, all instruments can be easily identified from left to right. Overall, it's great in this aspect.

Soundstage (3/10)
Soundstage in IEMs is generally not impressive, and the same applies to the CVJ Mei. Everything seems to be placed right there, lacking width or height in any of my orchestral tracks.

EQ Performance (7/10) – It's important to note that my EQ presets are specifically tailored to my preferred sound signature. They are not a one-size-fits-all solution.
Moving on to my specialty, maximizing the potential of EQ settings. The CVJ Mei responds reasonably well to my EQ adjustments. I was able to address some peaks in the treble region and reduce the bass as well. The sound improved significantly compared to the stock settings. However, it's worth mentioning that EQ adjustments can only go so far. The sound still struck me as somewhat unnatural or artificial, but the overall tuning was undoubtedly enhanced.

My Personal EQ for this IEM:
360081121_569655462047518_6586623138019003981_n.jpg


Conclusion:
So, should you buy the CVJ Mei? At a price of $59, I can't recommend the CVJ Mei solely based on its imaging and separation capabilities. While this may be beneficial for those who enjoy casual gaming to distinguish left and right, the soundstage is not satisfactory. The tonality of this IEM is not bad, but there are other IEMs that offer a more natural sound. Male vocals excel in this IEM, as well as instruments like trumpets, piano, and violin. However, the bass and treble can sound artificial, sometimes overpowering the mids of the IEM.

BGVP DN3 - A Review by Zeng

I will be giving a rating for each category of out of 10. (10 being the highest, 1 being the lowest)

Bass (8/10):
The bass of this IEM for me is plenty enough already. However, it doesn't go down as deep as full over ear headphones would be. When listening to Killing Strangers by Marilyn Manson. The start of the track have a very strong bass. It hits hard, but the sub-bass was lacking for me. It easily cuts off at 80hz. But overall, the bass is plenty enough for average consumers to like them. I would also like to mention that this IEM is warm and lush sounding.

Mids (9/10):
Now for the mids, this is where this IEM shines. It is really mid-centric to the point that sometimes I feel like the singer is singing beside my ears. It is very lush sounding and non-fatiguing. If you love vocals, then this IEM for me is perfect for you. However, it is important to note that the middle to lower mid-range of this IEM is a bit elevated to the point that it can sound a bit nasally. But nonetheless, it is forward and personal to my ears.

Treble (5/10):
Since I've mentioned earlier that this IEM is warm sounding, then it means that its treble performance is a bit worse. However, it doesn't mean that it's muddy or not detailed. It still performs pretty okay but lacks that energy up top. So if you're one of those audiophiles that loves to listen to every detail on a track then this is definitely NOT for you. There's not much to say on the treble region as it's just lacking on that energy up top for me. Particularly on the 10khz.

Soundstage (2/10):
Nope. The soundstage on this IEM is just not present at all. It is just mid-centric and forward sounding. No depth and height.

Imaging (6/10):
Well, the imaging of this IEM performs pretty decent. I can easily identify whether the instrument is playing from the direction of a compass. However, it still sounds like a regular stereo type of IEM.

EQ Performance (9/10):
This is the most interesting portion of this review. When applied to my preferred EQ settings in UAPP or Peace. It sounds really good! No distortion and it responds really well to EQ. If I were to give it a ranking after EQ this will easily a 5/5 ⭐ rating.

My personal EQ for this IEM:

Conclusion:
The BGVP DN3 has been given to me as a gift by my fellow friend @RemedyMusic and at first it sounds like my HD650/6xx. However, with a little tweak in the EQ, for me it is already end game. I don't think I'm going to need to have a more expensive pair of IEMs. The target market of this earphones are for those who wants to have a relaxing, warm sounding earphone, that have a forward presentation and vocal focused sound in their tracks. It is NOT for those who seeks detail in their tracks.
