The RS 185 is a headphone system which features a manual level control for precise sound reproduction. Coupled with wireless connectivity and a light, comfortable fit, these headphones have been created for serious music lovers. Brilliant, Bespoke Wireless Playback Delivering precise sound reproduction in an uncompressed digital quality - for analog and digital audio inputs - these wireless headphones carry seamless sound up to 100 metres away from the transmitter, so you can wander from room to room without losing signal. Better still, the conveniently located manual input level and balance controls make setting the listening levels to your individual preference a simple action. This means that you'll be able to fine-tune the details of each track in stunning acoustic clarity. Simple Set-Up All you'll need to do is to connect up the multi-purpose transmitter to your home sound system (via optical or analog inputs) and become immersed in your favourite playlists. You can even get a friend or family member involved because the transmitter supports up to two pairs of headphones simultaneously. Charge It Up On The Cradle This transmitter also functions as an ‘easy-charge' cradle and docking station so you can make the most out of the 18 hours battery life and thereafter.
