Sennheiser RS 120-W review

The RS 120-W is the most straightforward set on the list. Sennheiser says there is no pairing: plug the transmitter into the TV's analog audio output with the included RCA cable or 3.5 mm adapter, and the headphones play. A switch on the base picks Speech, Music or Neutral mode, and the Speech mode is the one to try for dialogue. Maximum volume is 100 dB, and a wheel on the headset sets volume independently of the TV. The 215 g on-ear headset uses fabric earcups and a low-pressure headband, and Sennheiser rates the rechargeable AAA NiMH batteries at up to 20 hours, with a 60 m range. Because it is built on LE Audio, one base can broadcast to dozens of RS 120-W headsets at once. The drawback is connection: Sennheiser documents analog inputs only, so a TV with just optical or HDMI audio out needs a converter. At $159.95 it costs more than the Avantree and Simolio picks.
