The hf3 in-ear headphones from Etymotic Research provide high-quality performance in a compact and affordable 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 Kevlar-reinforced cable offers lasting durability and has an inline 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. The standard 3.5mm plug provides compatibility with a variety of MP3 players, CD players, and other devices. The headphones have an elegant soft touch finish that's available in 3 different colors, perfect for matching your iPod, mood, or outfit. A compact pouch is included for storage and travel.
