Sennheiser RS 275 Delivers Private, Wireless TV Listening
As modern televisions continue to prioritize slim profiles, built-in speakers often struggle to deliver clarity and impact, especially at lower volumes. newsroom.sennheiser.com/rs-275-wireless-tv-headphones-auracast were designed to address that limitation directly, offering a dedicated wireless listening system that restores intelligibility and control without disturbing others in the room.
The RS 275 bundle pairs the lightweight HDR 275 over-ear headphones with the BTA1 digital transmitter, forming a closed system optimized for television use. Using Auracast transmission powered by the LC3 Bluetooth codec, the system maintains tight audio-video synchronization while supporting stable wireless playback across distances of up to 50 meters. The headphones can also connect independently to Bluetooth-enabled devices such as smartphones and tablets, allowing the system to extend beyond the TV when needed.
With support for multiple audio inputs and automatic source switching, the RS 275 integrates smoothly into modern entertainment setups, including TVs, media streamers, and game consoles. The result is a personal listening solution that prioritizes clarity, consistency, and ease of use.
Comfort, Customization, and Long-Term Use
The HDR 275 headphones were engineered for extended listening sessions, combining a low overall weight with breathable fabric ear cushions designed to reduce heat buildup. Physical controls on the earcups provide direct access to volume, power, and call handling, allowing operation without navigating menus or touch gestures.
Battery performance supports up to 50 hours of continuous playback, and charging can be handled either through the transmitter’s USB-C port or a standard household charger. Both the ear cushions and battery are user-replaceable, extending the usable lifespan of the system, while the included metal headphone stand keeps the setup organized when not in use.
Additional personalization is available through the Smart Control Plus app on iOS and Android. Within the app, users can adjust left-right balance, apply hearing profiles, shape the overall EQ response, and enable features such as noise suppression and mono playback. These tools are especially useful for dialogue-heavy content or older programming where clarity takes priority over spatial detail.
BTA1 Transmitter and Auracast Integration
At the center of the system is the BTA1 TV Transmitter, which handles Auracast broadcasting and device management. The transmitter supports optical, 3.5 mm, and HDMI ARC inputs, allowing it to connect to a wide range of televisions and audio sources. Auracast enables the BTA1 to broadcast audio to compatible headphones, earbuds, hearing aids, or speakers within range, making it suitable for shared listening environments as well.
Manual controls on the transmitter provide quick access to input selection and sound modes, including virtual surround and enhanced speech clarity. When paired with a smartphone over Bluetooth, the BTA1 allows deeper configuration, including video delay compensation, broadcast naming, password protection, and hearing aid modes.
Power is supplied via USB-A, with pass-through charging available for the headphones. The compact design allows the transmitter to sit discreetly on the included stand or near the TV without adding visual clutter.
By focusing on straightforward setup, stable wireless performance, and flexible personalization, the RS 275 positions itself as a practical solution for viewers who want clear, controlled audio without reworking their entire home theater setup.
