The ER3XR was created for listeners who appreciate the characteristic precision and isolation of Etymotic but prefer a slightly stronger presence in the deep bass. The ER3XR is the perfect option for audiophile bass lovers.

The ER3 series is finely tuned to very low tolerances, achieving unmatched playback accuracy. The precision-engineered metal housing of the ER3XR is very slim, and the detachable cable has been specially reinforced.

Various silicone and foam ear tips provide external isolation between 35 and 42 dB, and the 1.2-meter reinforced cable can be easily replaced thanks to the MMCX connector. The package includes replacement filters along with a tool for changing them and a convenient storage pouch.
