Our take on the brand
Our Summary
Product Strengths
- Excellent sound quality, potentially challenging cabled IEMs, with a dynamic and holographic rendering and beautiful mids and airy treble.

- Wide soundstage, creating a spacious and immersive listening experience.
Product Considerations
- Connectivity issues with LDAC, especially outdoors or in areas with interference, leading to intermittent signal drops.

- Vs HIFIMAN Svanar (wired): Svanar Wireless soundstage is taller and wider but not as deep, since clarity isn’t as sharp and clean, silence being more ”noisy”.
- Vs Sony WF-1000XM4: The Svanar Wireless presents a much more detailed, natural and sophisticated kind of sound, while Sony has bloated bass, that overwhelms everything else.
- Vs Apple AirPods Pro: The Svanar Wireless generally outperforms the AirPods Pro in sound quality.

Our take on the brand
Our Summary
Product Strengths
- Visceral and textured bass, especially given the implementation of the bone conduction driver
- Gorgeous, eye-catching design with hand-painted faceplates
- Balanced Armature helps create forward and engaging mid-range
Product Considerations

Comparisons (according to reviewers)

- Plutus Beast is more energetic and V-shaped in balance with greater treble boost and focus, as well as similar roll off pass 10khz when compared to the BQEYZ Wind
Takeaway: The Celest Plutus Beast is a beautiful IEM with a different sound. It has fun bass and good mids, making it a very interesting item for its price point.

Our take on the brand
Our Summary
Product Strengths
- Neutral tuning makes it suitable for studio monitoring, mixing, and mastering.
- Clean and transparent midrange with lively vocals, great for vocal lovers.

- The unvented design may cause pressure buildup for some users.
- Build quality might seem minimalistic, not fancy for the price.
- The treble can be too safe, missing some of the mid-treble sparkle and edge.
Comparisons (according to reviewers)

- Studio 4 has better detail retrieval, resolution, tone, and timbre, plus a better overall presentation than the JQ 4U Pro, though the 4U Pro is warmer with a thicker bottom end.

- Studio 4's mids are more forward than the Softears Volume, which makes vocals shine with a natural and accurate projection.
