Sennheiser RS 275 TV Headphones Go Big on Sound
Senn RS275 In Situ Headphones TV
Modern televisions are miracles of engineering. They are impossibly thin, absurdly sharp, and sound like they are whispering through a sock. This is not progress. It is compromise. And it is exactly why Sennheiser has announced the Sennheiser RS 275 TV Headphones, a system designed to give your TV back the one thing it lost on the way to being wall art. Sound.
This is a proper wireless TV headphone bundle, built to let one person enjoy thunderous explosions, murmured dialogue, and late night sport without waking the dog, the kids, or the entire street.
Auracast barges into your lounge room
The RS 275 bundle pairs the ultralight HDR 275 headphones with the new BTA1 TV transmitter. Together they use Auracast transmission technology powered by the LC3 Bluetooth codec. Translation, the sound arrives exactly when the lips move. No delay. No echo. No sense that something has gone terribly wrong.
Range is rated at up to 50 metres, which means you can wander off mid movie, open the fridge, reconsider your life choices, and still hear everything perfectly. The Sennheiser RS 275 TV Headphones can also connect directly to phones and tablets, making them useful well beyond the TV room.
Set it up, sit down, done
Sennheiser insists the RS 275 can be running minutes after unboxing, and they are not exaggerating. The headphones are pre linked to the transmitter, the cables are colour coded, and there is nothing clever enough to confuse anyone.
Once connected, the system delivers full range sound tuned for vocal clarity and proper bass. This matters, because modern television dialogue has a habit of being mumbled quietly while explosions try to punch through the wall.
If you want more control, the free Sennheiser Smart Control Plus app unlocks balance adjustment, hearing profiles, transparency mode, dialogue enhancement, and even a find my headphones feature for when they inevitably vanish into the couch.
Built for serious viewing sessions
The HDR 275 headphones are absurdly light, closer in feel to a remote control than a piece of audio equipment. The breathable fabric ear cushions are designed for long sessions, and the large tactile buttons mean you can adjust volume and power without fumbling about like a confused meerkat.
Battery life is quoted at up to 50 hours, which is enough to get through multiple seasons of something questionable without thinking about charging. USB C charging keeps things simple, and both the battery and ear cushions are user replaceable, which feels almost rebellious in 2026. A sturdy metal stand is included to stop everything ending up in a tangled heap.
The BTA1 does the heavy lifting
The included BTA1 TV Transmitter is the unsung hero. It broadcasts audio using Auracast to compatible headphones, earbuds, hearing aids, and speakers, effectively turning your TV into a wireless audio lighthouse.
It supports optical, 3.5mm, and HDMI ARC inputs, meaning it will work with almost anything that makes noise. Physical buttons allow switching between inputs and sound modes such as virtual surround and enhanced speech clarity, while the app handles deeper settings like auto input switching, video delay compensation, and Auracast broadcast controls.
Australian launch details
The Sennheiser RS 275 TV Headphones bundle will be available in Australia from 17 February 2026, launching exclusively through Harvey Norman, both in store and online, priced at $549 AUD.
A version without the stand, sold as the RS 255 TV Headphones, will be available through Sennheiser’s official online store for $449 AUD. The BTA1 TV Transmitter will also be sold separately for $349 AUD.
In short, Sennheiser has looked at modern TVs, shaken its head slowly, and built something that fixes the problem properly. Loud for you, silent for everyone else, and no arguments required.
