What reviewers say about the 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.

Where reviewers disagree 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.

The Etymotic ER4XRs' top qualities are the detail and definition of the midrange, rewarding the closest listening.
As these earphones are non-ported, the foam tips provide fantastic isolation, all-but unbeatable among universal earphones.
The slim cylinders work their way deep into the ear canal, which feels invasive.
the $350 Etymotics ER4XR (Extended Range) in-ear headphone is tuned to near perfection, with just a smidgen more bass than their equally good-sounding and like-priced ER4SR (Studio Reference) cousins
I also found the three-flange design spreads the pressure on my ear canal more comfortably than a single piece of memory foam
If I had to be picky, I'd say I'd like a wee bit more high-end sparkle, but that's just a matter of taste, and sparkle can get tiring over the long run.
the Etymotic ER4 are reference-grade in-ears for folks who want the best sound quality on the planet
the upper mids and highs become sharp, sibilant and generally dominate the sound when listening to a less than pristine source like Spotify
Should you want something a bit heavier in the low-end, you can always opt for the XR version of the headphones, which put more emphasis on bass and sub-bass frequencies.

Source: etymotic.com (verified 2026-07-11) · corroborated by headfonics.com. The Etymotic manufacturer product page (etymotic.com/product/er4xr-earphones) confirms this exact ER4XR model via its Technical Specs block: single high-performance balanced-armature driver per channel, 45 Ohms @ 1kHz impedance, 98 dB @ 1kHz/1mW sensitivity, 20 Hz–16 kHz frequency response, a detachable 5 ft cable with MMCX connectors terminating in a 3.5mm gold-plated stereo plug, and CNC-machined anodized-aluminum shells; the page shows a current store price of "$ 309.99". The Headfonics review (Jan 4, 2017) corroborates the identical spec table and states the ER4 was relaunched in 2016 with the SR and XR "at 349 $ each," establishing the $349 US launch MSRP. Both pages unambiguously identify the ER4XR (eXtended Response, added bass) variant as distinct from the flat-tuned ER4SR sibling that shares the cable and body but differs in bass tuning.
