Altec Lansing BackBeat 326

Altec Lansing's Backbeat series of in-ear headphones are geared for "on the go" listening and optimized for iPods and similar MP3 players.  Soft, flexible cushions conform to the shape of your ear canal for improved bass response and maximum reduction of distracting noise.  The Backbeat 326 (aka "Backbeat Titanium") is the top-of-the-line model and offers an impressive 10 Hz to 20 KHz frequency response, thanks to titanium-enhanced micro-speaker drivers.  It comes with three different sizes of silicone cushions to ensure a snug but comfortable fit, as well as a pair of dual-flange tips offering extra isolation for particularly noisy environments.  The Backbeat 326 weighs under an ounce and comes with a neoprene carrying case, a gold-plated plug, and nearly four feet of tangle-free cloth cord.
