Sennheiser RS 275 TV Headphone Bundle with Auracast for Private TV Listening

For decades, Sennheiser has been a familiar name in personal audio, with a strong focus on solutions that adapt sound reproduction to real-world listening environments. As televisions become ever slimmer and living spaces more shared, the demand for private, intelligible TV sound continues to grow. Positioned precisely in this context, the Sennheiser RS 275 TV Headphone Bundle addresses the need for individual listening without affecting others in the room.

A Dedicated Bundle for Private TV Audio

The RS 275 TV Headphone Bundle is built around a clearly defined concept: transmitting TV audio directly and individually to the listener, rather than replacing speakers or soundbars. The system pairs the HDR 275 wireless over-ear headphones with the BTA1 TV transmitter as a pre-configured solution, allowing users to start listening with minimal setup effort. This makes the bundle particularly appealing for viewers who want consistent sound quality at any time of day without adjusting the TV’s main volume.

Auracast at the Core

At the heart of the system is the BTA1 TV transmitter, which uses Auracast as an open Bluetooth standard for audio broadcasting. By relying on the LC3 codec, the transmitter is designed to provide stable connections with low latency, ensuring that dialogue remains synchronised with on-screen action. HDMI with ARC, S/PDIF optical, and a 3,5 mm stereo mini-jack input allow the transmitter to connect easily to a wide range of televisions, including modern Smart TVs with built-in streaming apps.

Auracast also opens up additional use cases beyond a single TV setup. Compatible smartphones or tablets can act as alternative audio sources, extending the system’s usefulness across different listening scenarios within the home.

Sound Personalisation via App

Fine-tuning the listening experience is handled through the Smart Control Plus app, available for Apple iOS and Google Android. Users can adjust equaliser presets, enhance bass response, and activate features aimed at improving speech intelligibility. Balance controls and optional noise reduction further support individual hearing preferences, particularly when watching dialogue-heavy content or older productions with limited audio clarity.

“TV screens are becoming ever thinner, and with them their built-in speakers. This makes it increasingly difficult to enjoy intelligible sound without disturbing others. The RS 275 TV headphone system delivers complete listening privacy and sound quality designed to turn every moment in front of the TV into an experience.”

Comfort and Everyday Usability

The HDR 275 headphones are designed for long viewing sessions, combining a lightweight construction with soft, breathable ear pads. Physical controls on the ear cups allow volume adjustment and basic operation directly on the headphones, reducing the need to reach for a remote or smartphone during use. With a battery life of up to 50 hours, the system is well suited for regular daily viewing, while replaceable ear pads and battery contribute to long-term usability.

Additional Transmitter Functions

Beyond basic audio transmission, the BTA1 offers extended settings via the companion app, including virtual surround options and lip-sync fine adjustment. Users can also manage multiple audio sources and define stream names or password protection for private Auracast broadcasts. Power is supplied via USB Type-A, typically from the TV itself, while an integrated USB Type-C port allows the headphones to be charged directly at the transmitter.

“For us, it was essential to make setup and operation as simple as possible so users can get started immediately. The headphones are paired with the transmitter right out of the box, and all connections are marked with practical colour codes. For those who want to tailor their audio experience in detail, the Smart Control Plus app offers intuitive personalisation directly from a smartphone.”
