Sennheiser has just announced three new wireless headphones that promise to deliver high-resolution, movie-theater-quality audio via uncompressed wireless transmission from Kleer, and are equipped with dynamic transducers. The Kleer transmission technology used in these headphones operates without compression and can be used without any audio detail loss. One of the main differences between the three models is the maximum distance that they can operate under, with the RS 160 listed at 65 feet, RS 170 at 262 feet, and the RS 180 at 328 feet. Up to four individual headphone receivers can be used with each system, which makes it suitable for a family movie night. Expect to pay $200, $250, and $300 for the RS 160, RS 170, and RS 180 respectively.
