Select products
LETSHUOER DZ4
- Positioning: A budget-oriented IEM designed for everyday use with a unique dynamic driver setup.
- Description: Combines three 6mm titanium dome dynamic drivers with a passive filtering module that helps maintain clarity in a compact design. Compared to other models like the DX1 or S08, it offers basic sound performance ideal for standard personal use at a low price, suitable for buyers with modest budgets and conventional connectivity needs.
LETSHUOER S08
- Positioning: An entry-level planar IEM using advanced production techniques.
- Description: Uses a fourth-generation dual voice coil planar driver enhanced by nanoscopic magnetron sputtering and a PTR elastic film surround to improve stability and low-frequency response. Compared to the DZ4 and DX1, its planar technology delivers a distinct tonal character that may appeal to users needing precise monitoring in controlled environments.
LETSHUOER DX1
- Positioning: A mid-range IEM featuring a self-developed 11mm dynamic driver with additional tuning features for versatile listening.
- Description: Includes a built-in 5kHz notch filter and high-precision CNC components that help reduce distortion and refine sound detail. Relative to the entry-level models, it provides enhanced clarity and richer detail.
LETSHUOER Mystic 8
- Positioning: A high-resolution IEM designed for live performance and detailed monitoring with an eight balanced armature driver array.
- Description: Features eight BA drivers paired with a low-pass filtering module, three-way electronic crossover, and four-way acoustic tube to ensure controlled bass and crisp high frequencies. Compared to the dynamic models, its complex driver configuration offers greater sound precision and depth.
LETSHUOER Cadenza
- Positioning: The flagship in-ear headphone, built with a hybrid driver system and premium materials.
- Description: Combines 12 hybrid drivers, a titanium chassis, and a 204-strand cable made from 6N monocrystalline copper and silver hybrid elements to deliver balanced tone and clarity. When compared with all other products in the lineup, it is aimed at audiophiles who require cutting-edge technology, superior build quality, and advanced functionality for critical listening and professional studio use.

Product Strengths
- Excellent build quality with a CNC titanium alloy material shell, giving it a premium feel
- Many reviews praise the natural and well-tuned midrange
- An airy and sparkly treble region that is not fatiguing or offensive
- The fit and comfort are excellent due to its smaller shell and ergonomic design
- The packaging and accessories are nice and extravagant, contributing to a premium unboxing experience
Product Considerations
- The bass response is underwhelming, lacking mid-bass emphasis and sub-bass authority, and may not satisfy bass enthusiasts
- The stock cable is often considered flimsy and not up to par for a flagship-level IEM, and lacks modularity
- The unique design of the faceplate may not appeal to everyone
- Some reviewers mention a lack of pneumatic pressure relief, leading to pressure buildup in the ear canal for some users
- Some dryness in the treble region
Comparisons (according to reviewers)
- Compared to Moondrop S8, the S8 does not have the same contrastiness, but offers more microcontrast and texturing in vocal content
- Compared to 7th Acoustic Supernova, the Supernova has better imaging performance and adds more mid-bass
- The Mystic 8 reminds reviewers of the Cadenza 4 (particularly the midrange)
- Vs Letshuoer Cadenza 12, the Cadenza 12 has more bass volume and depth, superior dynamics, imaging, and staging, but the Mystic 8 has more open mids
Takeaway: The Mystic 8 is a well-built IEM with a balanced and natural sound, making it great for critical listening and those who appreciate a mature and refined sound signature. Comfortable and technically proficient, it is a great choice for those who prioritize clarity and detail retrieval over emphasized bass.

Our take on the brand
Product Strengths
- Premium build quality and materials with luxurious Nappa leather detailing and a cast aluminum yoke
- Comfortable for long listening sessions with soft earcups and a headband that provides even pressure distribution
- Excellent sound quality with 40mm carbon cone drivers delivering ultra-fast response, low distortion, and a clean, smooth sound signature
- Effective active noise cancellation (ANC) reduces low-frequency sounds and midrange chatter, with the Nappa leather providing a tighter seal
- Realistic soundstage scale with tight, well-defined imaging, with the sound feeling more live and in front of the listener
Product Considerations
- Multipoint pairing is not always seamless, and there might be occasional wind noise from the earcup due to software glitches, with wear detection being inconsistent and inaccurate
- Limited app customization with only bass and treble adjustments, lacking a fully customizable EQ
- Microphone pickup is good in quiet environments, but can be affected by heavy noise gating in noisy conditions, causing voice fade-in/out
- Some emphasis on bass response, which may not appeal to everyone
- There is concern about the Nappa leather being easily scratched
Comparisons (according to reviewers)
- Compared to the PX7 S2, the PX8 offers better sound quality with greater instrument separation and realism due to the carbon fiber drivers, and also features more premium materials
- While the PX8 active noise cancelling does well, Sony still has better mic pickup
- The PX8 provides a good alternative to the Airpods Max
- The PX8 stacks up among some of the best wireless headphones along with the Focal Bathys
Takeaway: The Px8 is a premium wireless headphone with outstanding build quality and sound performance, which is perfect for audiophiles seeking a luxurious listening experience. It combines comfort, effective noise cancellation, and detailed audio reproduction, making it a worthwhile investment for those prioritizing sound quality and high-end materials.

Our take on the brand
Product Strengths
- Unique octagonal design made of quality materials, with a rugged, serviceable build quality featuring exposed nuts and bolts.
- Surprising amount of bass for an open-back, on-ear headphone, that is solid, tangible, present, well balanced and well tuned.
- The silver-plated OCC copper cable is lightweight, pliable, ergonomic and does not remain bent after staying still.
- Comfortable on-ear headphone, especially considering it's an on-ear design, with thick, soft pads and a comfortable headband.
- Easy to drive with portable devices like dongles or smartphones.
Product Considerations
- Being an on-ear design, the Thalia can become uncomfortable after extended listening sessions (45 minutes or longer) due to pressure on the ears.
- Not the most compact headphone, and does not fold up, limiting its portability somewhat.
- The open-back design results in sound leakage, making it less suitable for noisy environments or situations where discretion is required.
- The height adjustment mechanism, while providing fine control, is a bit fiddly and not easily adjustable on the fly.
- Its lower-midrange will be too full for some.
Comparisons (according to reviewers)
- The Thalia is far superior to the Koss Porta Pro and sets a new standard for portable on-ear headphones, but it is inspired by the Porta Pro.
- Compared to the Grado RS2x, the Thalia is more durable, comfortable, and more enjoyable overall, and is more bassy and thicker in the midrange.
- The Thalia has a faster pace and a better driver control, and offers a lot more in the top-octave than the Sennheiser Momentum 2/3.
Takeaway: The Thalia is a uniquely designed, portable on-ear headphone that delivers great sound and is built to last. It is a good option for those who want a distinctive headphone that is fun to listen to.

Our take on the brand
What competes at this price?
Our Summary
Product Strengths
- Comfortable and ergonomic design, suitable for long listening sessions.
- Noticeably dynamic bass for a planar IEM.
- Smooth and refined sound signature.
- The soundstage is bigger than most IEMs in this price range, well expanded, nicely rounded stage which has very good height, width and depth, giving it a more 3D like imaging.
Product Considerations
- Treble is unremarkable and can become lost and incoherent.
- Midrange can feel like they are lacking a bit of substance.
- Cable is a bit thick and heavy.
- Stock cable is very rigid.
Comparisons (according to reviewers)
- Vs. Yanyan Canon 2: Canon 2 sounds more natural overall, the upper mid-range emphasis from the S15s does make them sound a bit dry in comparison, there's just a little bit too much texture in the upper mid-range, and it makes it a less natural, less smooth, and less coherent overall sound.
- Vs. Timeless and S12: S15 is much smoother and more refined, more even in its dynamics and laid back while still maintaining the same technical performance.
- Vs. Wu Zetian: S15 is cleaner, smoother and more refined, not as sizzly and energetic in the treble and the upper mids, and the low end isn't as emphasized like the original Wu.
- Vs. Blessing 3: S15 sounds more weighted, fuller and not as peaky in the upper mids and the treble, but still airy.
- Vs. T2: S15 is slightly better when it comes to layering and separation, more air, and the stage feels more open.
Takeaway: The Letshuoer S15 is a smooth and refined IEM that delivers a bigger soundstage with a dynamic bass for a planar, so it's great for neutral sound. Its comfortable design and all-rounder signature make it a good choice for an enjoyable listening experience.

- Compact and lightweight stainless steel shell built with a unique design that fits most ear sizes comfortably
- Easy to drive, even on more affordable or older Android phones
Product Considerations
- Subdued and relaxed treble takes a backseat and lacks sparkle and shine

- Limited seal affects passive isolation during use, especially in louder environments
- Stock cable is a bit thin and may feel a bit low rent, considering how solid and nice the shells feel
Comparisons (according to reviewers)

- Vs Truthear Hexa: The Hexa sounds more balanced, more neutral, and overall more natural compared to the DX1
- Vs FiiO FD15: The FD15 offers more bass, particularly in the deep end, a darker, lusher midrange, and sweeter, more laid-back treble; the DX1 presents a more neutral yet slightly more aggressive tuning
Takeaway: The DX1 is a comfortable, well-built IEM with a focus on clear and natural vocals and mids, making it great for vocal-centric music and analytical listening. It is easy to drive and can be a good choice for those who prefer a neutral sound signature.

Our take on the brand
Our Summary
Product Strengths
- High-end design with premium materials (cloth and aluminum construction, aluminum accent rings, soft faux leather, stitch-free Nappa leather) gives a luxury vehicle feel and understated style
- Comfortable for longer periods thanks to the redesigned form and shape, upgraded pressure-relieving memory foam, oblong earcups for better pressure distribution, and ample room inside the earcups
- Superior sound quality is due to the revised custom 40mm Bowers & Wilkins driver with lower distortion biocellulose diaphragm and 20mm voice coil, carefully positioned and angled inside the earcups
- Integration with the Bowers & Wilkins Music app allows customization of noise canceling levels, ambient pass-through, and EQ tone control
- Improved clarity of voice on phone calls is due to the redesigned microphone pattern
- USB-C socket is the sole input option, though adapters are included
Product Considerations

Comparisons (according to reviewers)
- Compared to the previous PX7, the S2 has a completely different design, is smaller and easier to carry, and has significant technical improvements
- The PX7 S2 offers a more balanced sound than mainstream offerings by Sony or Bose, which tend to exaggerate mid-bass

Takeaway: The Bowers & Wilkins Px7 S2 headphones offer a great listening experience with excellent sound quality, beautiful design, and a comfortable fit. They are a solid choice for anyone who wants an upgrade over basic headphones and cares about both style and sound.
