The RS170 headphone offers a weighty, full-bodied and detailed sound. It will let you enjoy pure thundering bass, a virtual surround sound, or both audio treatments for your music or movies.

Sennheiser RS 170

Cordless headsets come in various shapes and sizes but few provide more satisfying home cinematic performances than the RS170. This wireless headphone system comprises of a pair of wireless headphones and a multi-purpose transmitter which also functions as an 'easy-charge' cradle and docking station.

Sennheiser's RS170 utilises Kleer's uncompressed digital wireless audio transmission, offering an effective range of 80m (line of sight), and can serve up to four pairs of headphones. The transmitter, like the headset, runs off two AAA batteries allowing you to hit the streets with wireless tunes

A weighty, full-bodied and detailed sound reproduction is what the RS170 offers. Sporting a couple of switchable listening modes - Dynamic Bass and Surround Sound, it will let you enjoy pure thundering bass, a virtual surround sound-scape, or both audio treatments for your music or movies.

The headphones' leatherette earpads and headband cushions provide for outstanding comfort while their closed, circumaural design prevents sound leakage.
