Designed to give the truest, most accurate sound possible, the Etymotic ER4SR offer a masterclass in quality sound.

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.

Studio reference standard
The ER4SR (Studio Reference) model has been created for the most natural, evenly balanced sound possible. No frequency is emphasised above the others, making these earphones ideal for those who listen to Classical, folk, jazz and acoustic music over bass-heavy music. With the SR version you hear exactly what the studio engineers intended.

Quality finish
The ER4SR 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 ER4SR 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.

Hear the music exactly as the studio intended, with the Etymotic ER4SR.
