Sennheiser RS 120-W - Wireless TV Headphones

The Sennheiser RS 120-W Wireless TV Headphones are designed to provide clear, high-quality stereo sound for television, movies, music, podcasts, and streaming content. Digital wireless transmission with LE Audio is used to deliver reliable audio, while three selectable sound modes—Speech, Music, and Neutral—allow the listening experience to be adapted to different types of entertainment. A maximum sound level of 100 dB SPL is supported, making dialogue, music, and other audio easier to hear when additional amplification is required.

Comfortable extended listening is supported by an open supra-aural on-ear design, plush fabric ear pads, and a low-pressure headband. Volume can be adjusted directly from the headphones using an ergonomic control dial, allowing listening levels to be managed independently from the television. With a wireless range of up to 60 meters and battery operation of up to 20 hours, greater freedom of movement is provided while TV programs and other media are being enjoyed.

The included TR 120-W transmitter also functions as a docking and charging station, allowing the headphones to be recharged simply by being placed on the stand. Broadcast Audio based on the LE Audio standard is supported, allowing multiple compatible RS 120-W headphones to receive synchronized audio from a single transmitter. Simple analog connectivity is provided through the included stereo RCA cable and 3.5 mm audio adapter, so complicated pairing procedures are not required.
