## What reviewers say

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. (Based on 3 reviews, 2017-05-11–2019-05-07.)

Praised: Reference-grade, near-perfect tuning with excellent midrange detail and clarity; Tasteful bass lift over the ER4SR without bloat or losing accuracy; Class-leading passive noise isolation from the sealed, non-ported design.
Flagged: No in-line mic or remote; wired-only connection; Deep-insertion, triple-flange fit feels invasive or strange for some; Analytical, sibilant sound that punishes low-quality sources; Expensive for the average user.
Disagreement: Comfort splits the panel: What Hi-Fi and TechRadar find the deep-insertion, triple-flange design invasive or strange and not something to wear out and about, while TechHive found the same flanges very comfortable for long sessions and easier on the ear canal than memory foam.
