Etymotic ER4SR


Released Jun 1, 2016

What's in the box

  • 1/4" stereo phone adapter
  • Assorted eartips
  • Carrying Case
  • Detachable 5 foot cable
  • Filter removal tool and replacement filters
  • Performance Certificate
  • Shirt Clip


If you're not into accuracy, it's hard to recommend these. That said, these are easily my new favorite pair of in-ears. If you want to hear your music with little embellishment, these live up to the Etymotic legacy.
Sound Guys
(Jan 2017)

These earphones are about insight, and if that’s what you’re after you can’t do much better. More lively, larger-sounding earphones are available, but when the ER4SRs' sound sculptures stand up to this much scrutiny, the simple scale of the sound starts to matter less.
What Hi-Fi?
(May 2017)

For $350, we expect in-ear monitors to offer gorgeous, full-spectrum response regardless of input, and modern bass-heavy fare sounds lackluster on these Studio Reference models.
