## What reviewers say

**Sennheiser IE 600** — All three whitelisted testers (SoundGuys, Tom's Guide, TechRadar) recommend the IE 600 as a premium wired IEM with outstanding detail and a durable zirconium build; only SoundGuys measured anything (5-10 dB foam-tip sub-bass isolation). Chief gripes are the high list price across all three, plus Tom's Guide's harsh-treble warning and a polarizing housing texture. (3 sourced reviews.)
