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 entry-level Backbeat 106 (aka "BackBeat Classic Mobile") offers a frequency response of 40 Hz to 17 KHz and up to 16 dB of noise reduction. It weighs in at less than one ounce and comes with three different sizes of silicone cushions to ensure a snug but comfortable fit. The Backbeat 106 comes with a gold-plated plug and nearly four feet of tangle-free cloth cord.
