Sennheiser RS 185 Wireless Headphone

The Sennheiser RS185 is a superb digital-based wireless headphone system offering very high quality sound for watching TV or movies. The RS 185 base station transmitter easily connects to most TVs using either digital or analog method.

The RS-185 headphone has full size earcups featuring a vented open-back design. It delivers a spacious tone with great dialogue clarity but no ambient noise isolation. That may be a good thing if you're wanting to remain aware of your environment while watching TV. Individual left / right volume and balance controls are handily built into the RS185 headphone.


The RS 185 headphone has full-size earcups with a vented, open-back design delivering a natural, spacious sound. The comfortable open construction allows you to hear sounds in the room. However, it may also "leak" out audio that could potentially be heard by others in the room sitting nearby. The Sennheiser RS 175model offers closed-back earcups if you prefer some listening privacy.

Individual left / right volume and balance controls are built right into the RS185 headphone and there's also a sensitivity adjustment for analog inputs with two volume modes: Automatic Level Control (ALC) or Manual Level Control (MLC).

The transmitter base station connects with either analog or digital/optical audio output from your TV. The base doubles as a charging stand for the wireless headphones. Expect up to 18 hours of playtime per charge. Claimed total wireless range is up to 328 feet (100 meters). The free 2-year Sennheiser manufacturer's warranty is always included with your headphone.com 'authorized dealer' purchase!

The Sennheiser RS185 system can be used with two Sennheiser 'HDR' wireless headphones at the same time. Purchase the HDR 185 headphone-only unit (sold directly from Sennheiser) along with this RS 185 system for a complete 2-person wireless listening setup.
