Building on the RS-120-W wireless headphones introduced in 2022, Sennheiser is doubling down on a very real problem that never seems to go away: TV audio that’s either too loud for everyone else or not clear enough for the person actually listening. The new RS 275 TV Listening Bundle is a purpose-built personal audio system designed for viewers who want intelligible dialogue, proper lip-sync, and freedom to move around the room without cranking the television or reaching for subtitles every five minutes.
At the center of the system are the ultra-light HDR 275 headphones and a compact BTA1 wireless transmitter, working together via Auracast transmission and the LC3 Bluetooth codec. That combination isn’t marketing fluff, it’s what delivers ultra-low latency audio that stays locked to the picture and maintains a stable connection at distances up to 50 meters. In practical terms, it means no echo, no lag, and no awkward delay when someone’s mouth is clearly moving but the words arrive late.
Add support for Bluetooth Classic, multipoint connectivity, and intelligent source switching, and the RS 275 isn’t just a TV accessory; it’s a flexible listening solution for anyone who wants clear, private sound across movies, sports, and streaming content without turning the living room into a negotiation.
Irene Strueber, Senior Product Manager at Sennheiser, said, “As screens continue to get thinner, their speakers have to follow, making it harder than ever to enjoy full-range sound without disturbing others. The RS 275 TV Headphones unlock total listening privacy and impressive clarity, whether your TV’s built-in speakers are underwhelming you or overpowering everyone else.”
Simplicity & Flexibility
The RS 275 bundle is designed to be up and running within minutes of unboxing without the usual pairing gymnastics. Once set up users can expand and fine tune the experience using the free Sennheiser Smart Control Plus app for Android and iOS. The app adds meaningful personalization including transparency mode left right balance adjustment hearing profiles device specific audio modes and even tools for locating misplaced headphones. In short it turns the RS 275 from a simple TV listening solution into a system that adapts to how and where you actually listen.
HDR 275 Headphones
The included HDR 275 headphones are lightweight and designed for comfort during long listening sessions. Breathable fabric ear cushions keep ears cool and provide a tailored fit that all but disappears once they are on your head.
Large textured buttons make volume control power and call handling easy to manage by touch alone with output levels reaching up to 106 dB. A single charge delivers up to 50 hours of listening and recharging is simple using the transmitter’s USB Type-C port or a standard household charger. Both the ear cushions and the battery are user replaceable helping ensure a long service life as the hub of your TV and multimedia listening. A sturdy metal headphone stand keeps everything organized when not in use.
The HDR 275 headphones use Sennheiser’s in house acoustic system tuned specifically for vocal intelligibility with a satisfying bass foundation. Built in listening tools allow users to enhance dialogue and immersion without pushing volume levels to the point of disturbing others.
When paired with the Smart Control Plus app users gain access to presets user defined equalizer settings bass boost and additional hearing enhancement options. Listeners can dial in greater clarity or added warmth and apply those preferences across all content. A selectable noise suppression mode is also included to reduce hiss and static while collapsing the signal to mono making it especially useful for classic films and older television shows.
More from Irene Strueber, Senior Product Manager: “It was important to make the setup and user experience simple so customers could get to listening immediately. In addition to the headphones being pre-linked to the transmitter out of the box, everything you need to connect is conveniently color-coded…And for those that want to truly make the audio experience their own, the Smart Control Plus app goes even deeper with intuitive personalization from the smartphone already in their pocket.”
BTA1 TV Transmitter
The included BTA1 transmitter adds a wide range of input options along with expanded audio enhancement capabilities making it easy to integrate into virtually any entertainment setup. Using Auracast technology the BTA1 can blanket an entire room with a stable wireless signal for compatible headphones such as the HDR 275 as well as earbuds hearing aids and powered speakers turning the TV into a shared yet still flexible audio source.
Top mounted buttons allow manual switching between inputs and sound modes including virtual surround sound and enhanced speech clarity when using TV or HDMI ARC sources.
Users can also connect a smartphone to the BTA1 transmitter over Bluetooth. This enables setup of automatic input switching and video delay compensation while giving access to Auracast controls such as broadcast name password protection and hearing aid modes.
Optical and 3.5 mm inputs provide flexible connectivity with TVs stereo systems laptops game consoles and more. An HDMI ARC input further expands compatibility allowing audio output from built in TV apps and streaming services or from connected A/V receivers.
The BTA1 draws power from a nearby device using a USB Type-A connection and passes power through to a USB Type-C port for convenient headphone charging. Its low profile design fits neatly on the included headphone stand or can be placed discreetly near the source without adding visual clutter.
