Magic Of Revealing Musicality – Letshuoer Mystic 8 IEMs
Letshuoer Mystic 8 is a $989 USD pair of Earphone IEMs with a high-end 8 BA Balanced Armature drivers inside, and the star of today’s review. Magical, thrilling and revealing, today we review the Mystic 8 and also will compare them with other similarly priced IEMs that we’ve recently reviewed, including Letshuoer Cadenza 12 2025 (1999 USD), ThieAudio Origin (849 USD), and Campfire Moon Rover (1199 USD).
Introduction
Letshuoer always creates interesting IEMs and Earphones, so when I heard that they have a middle-of-the-road flagship IEM, not quite as affordable as their entry-level earphones, but considerably more affordable than the Cadenza 12 IEMs, I was immediately curious to hear them. Mystic 8 is a very popular pair of earphones, and received glowing reviews from other listeners, so today we explore how they fit in the busty market of today’s audio world. Best part about those Mystic 8 IEMs is that they are available straight from Letshuoer, but also sold through Chifi popular sales channels including Linsoul, Hifigo, Aliexpress and Amazon.

Build Quality – Design
Letshuoer Mystic 8 is considered part of the Myst Series Design, the Phantom Cat, which is a short explanation of the model you can see on the shells. This is a pair of flagship-grade IEMS powered by 8 Balanced Armatures, including both Sonion and Knowles BA drivers.
With a 0.78mm 2-Pin standard IEM connector, and a high-end 8-Strand x 20 Core Single Silver Plated Monocrystalline Copper Cable, and Precision CNC Titanium Alloy Shell, Mystic 8 feels built like a tank, very similar to the impression that Candeza 12 gives, but being far more scratch resistant, as the black shells of Mystic 8 do not reveal usage at all.
For the 8 drivers inside, we have a Three-Way Crossover that is Electronic, and a Four-Way Acoustic Tube. Letshuoer also implemented a complex Low-Pass filter for the drivers dedicated to the bass, to enhance the bass presentation and limit how much treble / high-end bleeds into what you hear from those drivers in particular.
Now mentioning all the unique features of Mystic 8, they come with a really nice necklace, and a hard solid transport case, and they sport a SPL of 107 dB with an impedance of 18 OHMs.
Fit – Subjective Usage
Letshuoer Mystic 8 is a pair of IEMS with rather large shells that feel heavy, but in actual wearing they are super comfortable, they come with a sleep and flexible cable that has a complex braiding which cancels any potential handling noise. This is a 4.4mm balanced cable, and it has a tight coiling around my ears providing excellent wearing comfort and a secure, medium-depth fit. If there is any downside you ought to know before getting the Mystic 8, they leak quite a bit more than the vast majority of IEMs out there.
There is a bit of void that I can feel when wearing the Mystic 8, but they offer a stronger passive noise isolation than most IEMs, around -25 dB compared to the average of ~16 dB offered by all IEMs out there. Mystic 8 has no driver flex, as it has no dynamic driver, and while it is a bit big, I feel like they would fit someone with ears slightly smaller than mine. With a medium depth fitting, it is comfortable for sure.
You will have excellent comfort with the default eartips, and nothing in the Mystic 8 package needs an upgrade, they are already a fully upgraded pair of IEMs. Even the transport case included in the package is of an excellent quality, although the metallic part might scratch on the outside. Letshouer dopes include a rubber sleeving on the inside to avoid any kind of dents and scratches on the IEM shells.
Sound Quality
Pairings – I have paired the Letshuoer Mystic 8 IEMs with a selection of sources, including Rose Technics RT-5000, Dethonray Listening M1, Dethonray Clarinet, iBasso DX340, Lotoo PAW GT2, FiiO K17. Those are some of the most revealing sounding IEMS in the whole world, and you really need a high-end source to really take advantage of the resolution and clarity they have to offer. Mystic 8 is much harder to drive compared to most IEMs, and will eat up a lot of power despite the All-BA configuration and rather traditional otherwise setup. Mystic 8 is not sensitive to source noise and with most sources out there, you will not hear hissing and background noise.
Overall Signature – I always like technical and analytical sounding earphones, but Mystic 8 takes those abilities to a whole new level, sounding really crisp, sharp and detailed. It reveals absolutely everything in music, and the main signature is a purely neutral one, with no coloration except for a rather definite upper midrange peak that helps the analytical and technical sound stay tack sharp. Mystic 8 is defined by how crisp and fast it is, but this means that it reveals both the good and the bad in music, it is not a chill IEM and will be a magnifying glass for the good music, but for harsh, grainy textures too, it reveals absolutely everything.
Bass – Starting with the low-end, Mystic 8 sounds tight, precise, fast and accurate. It can render any texture, any speed, with utmost precision, staying neutral, controlled, crisp and thumpy. Most music does not have a strong bassline with Mystic 8 as they are tuned for pure neutrality and music rendering, they are the most crisp, most detailed and clean sounding pair of earphones at this price point. This also means that they are much closer in tuning to the original Letshuoer Cadenza 12 than they are to the new 2025 version. Bass can reach 20 Hz nicely, but it does not force any frequency to be more prominent, it allows you to hear exactly what the song has in store, bass becoming more audible and more strong above 40 Hz in general.
Midrange – Mystic 8 has an extreme resolution and detail in the midrange, it can render details previously unknown to the listener, but there’s a fairly specific peaking in the upper midrange which gives female voices and thinner male voices priority and more power, volume compared to deeper voices. This turns the whole sound a bit bright, but helps it sound more open, wider and more airy. This peaking range affects both the upper midrange and the lower treble, being broad enough to not sound colored, and tilt the entire signature towards this brightness. It is also reminiscent of ACG – centric tunings that can really squeeze the sweetest, most enjoyable presentations out of J-Pop, J-Rock and ACG music in general.
Treble – With a rather bright, open and sharp treble, Mystic 8 is one of the most detailed sounding IEMS out there, but this means that the top end is not very smooth, and instead it shows the true colors of your albums. Certain rock and pop is really nicely mastered and sounds perfect, while other songs are rather harsh and bright. Being a pair of earphones that do not emphasize or force music to sound sweeter / smoother than it actually is, allows Mystic 8 to be the perfect music production pair of earphones, it is revealing and crisp, and treble extends nicely up to 20 kHz, airy, open and bright.
PRaT / Textures / Dynamic – Being an analytical and technical sounding IEM, Mystic 8 is rather fast, technical which makes music more often than not quite grainy and harsh. This is because certain instruments are inherently a bit grainy and harsh, and most IEMS and headphones try to somehow hinder those frequencies or render them in a more organic way, but Mystic 8 with their all-Ba setup are the cold, honest truth of the audio world. Sound is more detailed, faster than it is dynamic, but Mystic 8 can render a high dynamic range, it will just pull your focus and attention more to details than the dynamic range.
Loudness Saturation Gradient – Mystic 8 eats so much power that they could be considered mini headphones, they really like to be powered with a strong source, and they need that to really come alive. Sound is great across all volumes, having a similarly good presentation regardless how loud you go, but it becomes more engaging, more dynamic and more balanced louder. There’s most certainly a high headroom and if you have the power you can squeeze a lot of performance from the Mystic 8.
Soundstage – Mystic 8 is a pair of IEMs that sounds rather holographic, wide, but not very deep. Layering is strong, and so is the instrument separation, as Mystic 8 has a neutral flat sound, but outstanding resolution. Because the tuning is quite neutral, it limits how deep the sound feels, and Mystic8 just feels precise and crisp, but depth usually requires more bass. This being said, there’s a huge difference between the sounds that come right in front of you and those that come from further away from you.
Comparisons
Letshuoer Mystic 8 vs ThieAudio Origin (989 USD vs 849 USD) – You will hear far more bass and impact from the Origin, as it is more of a basshead IEM, to the point where Mystic 8 sounds very bright in direct comparison. Origin has a full, lush sound with an organic midrange, and a smooth treble in comparison, but Mystic 8 reveals far more detail, gives more insight into music, and it is much more critical with the music source compared to the Origin. While both are outstanding earphones, I prefer the Origin for bassier music, and Mystic 8 for when I want to hear absolutely everything and analyse my tracks a bit. Music production is much easier and more precise with Mystic 8 thanks to the ultra detailed sound they have.
Letshuoer Mystic 8 vs Campfire Moon Rover (989 USD vs 1199 USD) – Campfire Moon rover is a more mid centric sounding earphone, with a strongly vocal sound compared to mystic 8 which sounds brighter, more crisp and sharper. Both IEMs are excellent for revealing details, but Moon Rover is much smoother, warmer, has more mid bass, more upper bass, and sounds more fluffy, bloomy and more relaxed. Mystic 8 is far sharper, more precise, more detailed, more technical, faster and more analytical. This leads to Mystic 8 revealing both the good and the bad in music much better. I would say that Mystic 8 is almost the perfect IEM for music production, mixing and mastering, while Moon Rover is more of a listening / enjoyment IEM that makes a lot of sense if you’re looking to jam, listen, lead back and relax.
Letshuoer Mystic 8 vs Letshuoer Cadenza 12 2025 (989 USD vs 1999 USD) – Cadenza 12 is a bit smoother in how it resolves textures, it will reveal a tiny bit more detail than Mystic 8 all while sounding more organic, having a deeper bass, wider and more holographic soundstage, and being easier to drive too. There’s no question that the package of Cadenza 12 is super premium, and they are more traditionally v-Shaped, but Mystic 8 sounds more analytical and technical, it can reveal the issues with a mix, aliasing, harshness and grain more easily, being a better music creating earphone, they can render more details, forcing them to come out of the song more.
Value and Conclusion
Although Mystic 8 is a flagship, it has far superior value than most flagships if you’re looking for the kind of analytical, revealing and uber detailed sound that they have to offer. The kind of resolution they have is usually found in the 2K USD – 3K USD price range, so detail addicts will be really happy to learn about Mystic 8 and to enjoy music through them.
At the end of the day, Mystic 8 is the kind of IEM that has a bright, open sound, and an exceptionally good detail revealing ability, a tight and clean bass, and a fast sound. Technical, comfortable and clean, Mystic 8 is perfect for anyone who wants insight into their music collection, and a fully recommended IEM.
