Wireless headphones are a wonderful invention, but while they're no longer the heavy, battery-killing monstrosities they used to be, they still suffer from one pretty major problem: sound quality. Typical cordless cans broadcast using FM, which has a much lower resolution than CD, and background hiss and interference can also affect the sound. Sennheiser thinks it has the solution: Kleer. Kleer's chipsets are designed to transmit audio wirelessly at CD quality (44.1kHz, 16-bit), and Sennheiser's stuck a whole bunch of them in its RS 160, 170 and 180 headphones.
