Experience the most powerful bass response, with the Etymotic ER4XR, Extended Response earphones.

Etymotic history

Over 30 years ago, Etymotic invented noise-isolating, in-ear earphones. Etymotic's original design, developed for auditory research and hearing testing, used balanced -armature receivers and established these speakers as the gold standard for high-definition, in-ear earphones.

Extended Response
The ER4XR (Extended Response) model has been created for a powerful, bassy sound. If you enjoy bass-heavy music then you'll love these earphones! Although designed for an extended bass response, they still meet Etymotic's high standards in other areas - so you can expect natural-sounding vocals and crisp high frequencies.

Quality finish
The ER4XR doesn't just meet the highest standards of sound, it meets the highest levels of construction quality, too. Metal bodies with an anodized finish are built to last - with the bonus of looking great!

Detachable cables
Supplied with a 152cm detachable cable, the ER4XR is protected from the worst happening. If the cable should break, then a new one can simply be plugged in -saving your previous earphones from the bin. Alternatively, fit an upgraded cable of your choice for enhanced sound quality.
