Etymotic Research hf3 Noise-Isolating In-Ear Stereo Headphones with Mic

The hf3 in-ear headphones from Etymotic Research provide high-quality performance in a compact package. The headphones feature precision-matched Accu·Driver balanced armatures to provide a better than 85% response accuracy with tight bass, clear treble, and an extremely high output sensitivity. User-replaceable ACCU·Filters protect the drivers from earwax and other debris to ensure lasting quality and clarity. The in-ear design and assortment of noise-isolating ACCU·Fit eartips provide a proper seal in the ear canal to reduce outside noise by 35-42 dB. A CUSTOM·FIT option is also available that allows you to purchase custom-made eartips that are specifically designed for your ears. The reinforced cable offers lasting durability and has an in-line microphone and remote control for use with iPods, iPhones, and iPads. The close-proximity high-sensitivity microphone provides clear vocal pickup, while the remote lets you play and pause music, skip tracks, and answer phone calls on the iPhone.
