Moondrop CHU
The Moondrop CHU is a budget-friendly wired IEM that delivers a lively, detailed sound signature with solid tuning for its price.

- Pro:Low distortion and clear sound
- Pro:Secure and comfortable fit
- Con:Average technical performance
- Con:Durability concerns
- Con:Weak lower mids
Sennheiser IE 800 S
The Sennheiser IE 800 S is a compact, high-end wired in-ear that impresses with its detailed, spacious sound and refined tuning, thanks to its single 7mm XWB driver.

- Pro:Natural, cohesive tuning with strong sub-bass
- Pro:Very small and lightweight for comfortable extended wear
- Con:High price that may not fully match performance
- Con:Noticeable cable microphonics
- Con:Not a neutral or linear frequency response
