## 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.)

**Etymotic ER4XR** — Three whitelisted testers (What Hi-Fi, TechHive, TechRadar) reviewed the ER4XR; TechRadar's is a joint ER4SR/ER4XR piece that discusses the XR trim explicitly. All three praise reference-grade midrange clarity, and two single out a tasteful bass lift over the ER4SR, but none ran lab measurements. Fit divides them: two call the deep insertion invasive or strange, one finds the flanges very comfortable. (3 sourced reviews.)
