The Letshuoer Mystic 8 is one of the audio equipments that make a statement the moment you lay eyes on them. Arriving as part of Letshuoer’s Turkey tour, it immediately sets the tone with its premium, almost mystical aura. Disclaimer: This unit arrived for its AG Turkey tour. Thanks to Letshuoer and AG.
The outer packaging, with its metallic sheen and ancient Egyptian cat imagery, feels more symbolic than decorative — like an artifact carefully preserved through centuries. Lift the lid, and a sealed treasure chest feeling greets you.
The IEMs themselves boast a full metal shell, solid and serious in the hand. Of course, metal has its downsides — fingerprints collect easily — but Letshuoer thought ahead and included a cleaning cloth.
Even before plugging them in, it was obvious: the ergonomic design is meant to nestle comfortably into the concha, hinting at excellent isolation potential.
With a hybrid setup featuring 4 Sonion and 4 Knowles balanced armatures, Mystic 8 promises a ride that’s both energetic and refined. However, those with smaller ears might find the shell size a touch bulky. And the mug-like carrying case is worthy.

First Impressions (HiBy R4 – Pure Music Mode)
Mystic 8 sat snugly in my ears, offering excellent isolation right out of the box.
With Toto’s Africa playing, the first thing I noticed was the expansive soundstage. Synth textures appeared vividly, though the upper treble had a slight shimmer. Transparency stood out immediately, giving life and vibrancy to the track. However, vocals lacked a bit of the body I expected — something I plan to revisit after some tip rolling.
When Polyphia – GOAT kicked in, Mystic 8’s technical chops showed their teeth. The speed and clarity were impressive, handling the complex math rock structure without smearing details. Yet even here, the low end — especially the kick drums and bass guitar — sat a little more politely in the mix.
Switching to Leonard Cohen – Nightingale revealed a strong acoustic performance. The resolution was crisp, with country instruments individually mapped across the stage. Still, I found myself wishing for a slightly darker background. This feeling continued into The Raconteurs – Many Shades of Black, where vocals were clean but the space behind them wasn’t as black or atmospheric as I hoped — and cymbals leaned a bit thin.
Thankfully, Riverside – Self Aware showed another side. The live stage depth was truly satisfying. The organic bass came through beautifully, with 3D imaging that allowed each instrument’s impact to linger in open space.
Finally, Skillet – Rise Up sealed the deal with thick rhythms and a satisfyingly layered stage. Even with stock silicone tips, Mystic 8 handled the punch of electronic rock with confidence.
Early impressions suggest an 80–90% performance ceiling — definitely promising and certainly worth more exploration.
Eartip Rolling
Swapping to gray-bored semi-transparent tips immediately pushed the stage closer and increased definition.
Bass became more playful and dynamic, and subtle details — like vocal layering — emerged more distinctly.
Moving to the final pair from the box (hard black stems with semi-transparent shells), vocals grew even sharper and more articulate. Female vocals flirted with sibilance at times, but overall control remained solid. Bass guitar lines, once harder to track, now cut through more cleanly.
With the right tips, Mystic 8’s 4BA+4BA triple-crossover setup really comes to life.
Source Pairings
With Snowsky Echo Mini
The first seconds revealed Mystic 8’s inherent power and clarity.
However, in genres like industrial rock, cymbal strikes and metallic resonances can become pronounced—depending heavily on volume and gain settings.
Above 22/120 volume or on high gain, the metallic sheen can grow fatiguing unless a NOS filter is engaged.
Bass slam was modest; Mystic 8’s neutral tuning and Echo Mini’s dark-analog flavor sometimes softened impact a bit more than ideal.
With Cayin N8ii
This is where Mystic 8 truly blossomed.
At just 20/100 volume in transistor mode, transparency and orchestral grandeur were undeniable. Switching to tube mode deepened the soundstage, warmed the textures, and injected a more lifelike, emotional layer to the experience — though at a small cost to microdetails.
Polyphia’s GOAT again demonstrated how even with the stock cable, Mystic 8 could pull off a truly engaging performance. Minor distortions at the end turned out to be recording flaws, not driver issues — confirmed by seamless playback with Haggard’s complex orchestral tracks.
Bass
Bass on the Mystic 8 is all about control and fidelity.
Rather than overwhelming or dominating, it provides exactly the right amount needed by the music. Self Aware by Riverside beautifully showcases how organic and natural the bass can be, supporting the stage without muddying it.
Those craving skull-shaking slam might find Mystic 8 a bit restrained unless paired with the right eartips and sources.
Midrange
Midrange is Mystic 8’s crowning achievement.
Vocals are forward, articulate, and textured, standing proudly within the soundstage. Instruments like guitars, violins, and banjos occupy their spaces cleanly, without ever crowding each other.
Depending on tips, the tonality sits somewhere between neutral and slightly warm, maintaining emotional connection without losing analytical clarity.
Treble
Treble presentation strikes a delicate balance: lively, detailed, but rarely harsh.
Toto’s Africa highlights a slight shimmer in the upper treble, adding a sense of air and sparkle.
Switching sources to Cayin N8ii’s tube mode smoothens and warms the treble even further, creating a romantic, immersive atmosphere ideal for orchestral and acoustic recordings.
Pros / Cons

Cons:
- Bass slam is polite, not aggressive
