Digital RF wireless headphone system

The Sennheiser RS 175 is a wireless headphone system designed for home entertainment. It includes a pair of circumaural headphones and a multi-purpose transmitter that connects to audio sources via optical input. The system uses digital RF transmission to deliver audio up to 328 ft line of sight.

TV viewers and late-night listeners

This system suits anyone who wants private TV listening without disturbing others, with selectable bass boost and virtual surround modes for movies or music. It supports two headphone pairs simultaneously for shared viewing. Buyers needing Bluetooth connectivity or mobile device pairing should look elsewhere, as the transmitter uses only wired optical and analogue inputs.

18-hour battery life with transmitter charging

The headphones provide up to 18 hours of operating time and recharge directly on the transmitter dock. This integrated charging design means the headphones are ready whenever the transmitter is powered, removing the need for separate cables or charging schedules.

Questions about this item

What audio outputs must my TV or amplifier provide to connect the TR 175 transmitter?

The transmitter accepts a digital optical input and analogue sources, so your TV or amplifier needs a matching optical or line-level output.

Can I keep my existing wired headphones connected while the RS 175 system is in use?

The transmitter occupies the optical or analogue output you choose; if your TV has only one such output, wired headphones cannot stay connected at the same time.

How do I confirm the RS 175 headphones are receiving a clean signal after setup?

The transmitter shows a status LED, the headphones deliver up to 114 dB SPL with THD below 0.5 %, and the charge LED verifies battery health.
