Earphones by Etymotic

Etymotic's Albert Arends was showing four models of the company's earphones. The Etymotic ER3SE (Studio Edition—$179) has a flatter response than the ER3XR (Extended Response—$179), which has "a bit of a bass lift" in the 100Hz-1kHz region. One major difference between these models and the higher level ER4 SR (Studio Reference—$349) and ER4XR (Extended Response—$349) is that only the latter are channel-matched to within 1dB.

All earphones have detachable cables and metal anodized bodies, and come with four differently sized eartips that are claimed to accommodate 98% of ear canals. The company also makes for its earphones foam tips that provide 32dB sound attenuation.
