SennheiserTV Auracast Headphones with BTA1 Transmitter (Model: RS 275)

About

Tired of the nightly tug-of-war over the TV remote volume? The Sennheiser RS 275 lets you watch your way without keeping the whole house awake. This premium wireless headphone and Auracast transmitter bundle delivers rich, immersive Virtual Surround Sound that stays perfectly in sync with the picture, while Speech Clarity lifts voices above the background noise so you never have to rewind to catch that crucial line of dialogue again. It comes pre-paired and ready to go straight out of the box, gives you up to 50 hours of listening on a single charge, and lets you roam up to 50 metres from the TV without losing signal. Thanks to Auracast, you can even share the same audio with as many compatible headphones as you like, each with its own volume. Whether it's a late-night rugby replay or a full-season binge after the kids are in bed, this is the upgrade your TV time has been waiting for.

Product Features

• Virtual Surround Sound: Sennheiser's high-end drivers create an immersive, cinema-style soundstage from any TV, so movies and sport feel bigger and more exciting.
• Speech Clarity: Selectively boosts human voices so dialogue is much easier to follow, even during whispered scenes or loud background music.
• Normalise Volume: Evens out sudden jumps in loudness, so ads and action scenes won't blast your ears while quiet moments stay clear.
• Personalised Hearing: Choose from four hearing profiles and adjust the level of each ear separately for sound that is tailored to you.
• Lag-Free, Perfectly Synced Audio: Auracast technology powered by the LC3 codec keeps sound and picture in step, with video delay compensation available via the app.
• Bingeable Battery Life: Up to 50 hours of playtime means you can watch for days between charges, and the battery is user-replaceable for years of use.
• 50m Wireless Range: A stable connection lets you move freely around your home without dropouts or crackles.
• Share With the Whole Family: Auracast broadcast mode streams to an unlimited number of compatible Auracast headphones, earbuds or hearing aids, each with independent volume, and you can keep the TV speakers on for anyone not wearing headphones.
• Effortless Setup: The headphones and transmitter come pre-paired with colour-coded connections, so you just plug in, switch on and start watching.
• Versatile Connections: The BTA1 transmitter accepts optical, 3.5mm analogue and HDMI ARC inputs, with auto-input switching for TVs, sound systems, laptops and consoles.
