What reviewers said
KZ ZVX Pro
The KZ ZVX Pro is a budget-friendly wired IEM built with a sturdy all-metal shell and a detachable cable for easy upgrades. It delivers punchy, textured bass with solid extension, along with good imaging and soundstage for its price, though its tuning leans slightly away from neutral and has a notable peak around 8 kHz. Passive isolation is just average, making it less ideal for noisy environments.
- Pro:Punchy, textured bass with strong extension
- Pro:Good imaging and soundstage for the price
- Pro:Durable all-metal construction
- Con:Minor 8 kHz peak can add brightness
- Con:Tuning is not perfectly neutral
- Con:Passive isolation is only average
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:Excellent detail retrieval and expansive soundstage
- 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
