The Sennheiser RS 275 pairs HDR 275 over-ear Bluetooth headphones with a pre-paired BTA1 Auracast TV transmitter, giving up to 50 hours of playback, a 50m range and optical and analog TV cables plus a headphone stand in the box. It suits TV viewers who want to set their own volume while others keep the TV speakers on or join on their own Auracast headphones.
Who the Sennheiser RS 275 is for
Late-night TV: The BTA1 plugs into your TV's optical or analog output with the included cables and streams to the pre-paired headphones up to 50m away.
Hard-to-follow dialog: Speech Clarity lifts voices and Normalize Volume evens out loud ads and quiet scenes, with four hearing profiles and separate left and right levels.
Watching together: The transmitter broadcasts over Bluetooth Auracast to any number of extra Auracast headphones, each with its own volume, and TV speakers can stay on where the TV allows it.
Binge sessions: Up to 50 hours per charge, with a user-replaceable battery and replaceable ear pads for the long run.
Phones and tablets: The headphones also pair with phones, tablets and other Bluetooth devices when you step away from the TV.
Skip it if: you want noise cancelling: the HDR 275 uses passive damping with an Ambient Awareness mode, and the BTA1 draws USB power from the TV or a USB adapter that is not included.
