The ER3XR Extended Response offers a modest bass boost, building on the sound quality of the ER3SE, while providing a slight bass boost for those listeners that prefer a stronger low end response.

No compromise, high-performance noise-isolating earphones that deliver best-in-class benefits and superior value, perfectly matched to the latest product innovations from most music players that support a 3.5-mm stereo phone plug.

Utilizing the balanced armature drivers regarded as the gold standard for high definition, in-ear earphones, ER3 series earphones are tuned to extremely tight tolerance specs for the most accurate sound reproduction on the market. The ER3XR is designed for listeners who value the accuracy and noise isolation for which Etymotic is known but prefer a more robust presence in the lower range.

The new ER3XR incorporates significant cosmetic and functional improvements, from sleek, precision machined metal bodies to the reinforced, user-replaceable detachable cable. A must have for bass loving audiophiles and consumers.
