ER4XR is Etymotic’s in-ear monitor for those who demand nothing less than the highest reproduction accuracy in the midrange and treble frequencies, but prefer a tastefully added bass presence. The ER4XR right and left channels are matched within an industry-leading 1dB across frequencies from 100 Hz to 10 kHz.

  • Nicely tuned, with slightly emphasized bass and mid-highs
  • Flange-style ear tips block most ambient noise
  • Very comfortable to wear for long sessions

ER4XR with its tastefully added bass is favoured by audiophiles and consumers who prefer a little extra bass presence when enjoying their music. This model is not bass heavy by any means.

ER4XR is the earphone for music lovers and Hi-Fi enthusiasts who want uncompromising accuracy in the midrange and high frequencies, but appreciate a bit of extra presence in the lower end. Like the ER4SR, the ER4XR is built with precision machined, anodized and laser-etched aluminum bodies and features user-replaceable detachable cables. The ER4XR also incorporates the stringent channel-matching standard used in the ER4SR. The ER4XR is ideal for anyone looking for exceptional sound quality with just the right amount of low-end enhancement.

Accurate Earphone Reproduction

For earphones to have 100% accuracy, a recording of a live performance must produce exactly the same sound at the eardrum as the original performance. To achieve this, the acoustic properties of the ear must be factored in. The acoustic resonance and horn effects of the ear change a flat audio signal entering the open ear into sound with a (2700 Hz) high-frequency boost, which is the same response heard at the eardrum in a typical ear.
