Sennheiser BTA1 TV Transmitter

The Sennheiser BTA1 TV Transmitter is designed to make wireless TV listening easier, more reliable, and more immersive than ever before. Built around modern Bluetooth Auracast™ technology, the BTA1 allows users to connect compatible wireless headphones quickly and effortlessly, eliminating the common frustrations of pairing issues, unstable connections, and delayed audio. Whether watching films, sports, or late-night television, the BTA1 ensures that sound remains perfectly synchronised with on-screen action for a natural viewing experience.

Designed with universal compatibility in mind, the transmitter works seamlessly with most televisions as well as AV receivers and other audio sources using HDMI ARC, optical mini Toslink, or analogue 3.5mm connections. Its compact design and straightforward setup process make it an ideal upgrade for anyone wanting high-quality private TV listening without complexity.

Enhanced Clarity and Immersive Sound Features

The Sennheiser BTA1 TV Transmitter offers more than just wireless convenience by incorporating advanced listening features designed to improve dialogue clarity and cinematic immersion. Speech Clarity mode helps make voices easier to understand, ensuring that conversations remain clear and intelligible even during complex soundtracks or action-heavy scenes.

This makes the BTA1 especially beneficial for users who struggle to hear dialogue clearly through standard television speakers. In addition, Virtual Surround Sound technology creates a wider and more immersive soundstage that enhances films, television shows, and live events with a more spacious presentation.

Combined with low-latency Bluetooth transmission, these features deliver a highly engaging listening experience that feels natural and detailed. The result is private wireless listening that maintains both the emotional impact and excitement of your favourite entertainment.

Auracast™ Multi-User Broadcasting Technology

One of the standout features of the Sennheiser BTA1 TV Transmitter is its support for Bluetooth Auracast™ broadcasting technology, allowing multiple compatible headphones to connect simultaneously to the same audio source.

This makes the BTA1 ideal for shared listening environments where several users want personalised headphone audio while watching the same content together. Each connected listener can independently control their own volume and sound settings without affecting anyone else.

The transmitter also allows TV speakers to remain active at the same time, making it easy for users with different listening preferences to enjoy the same programme comfortably. For additional security and privacy, the BTA1 supports optional encrypted audio streams with password protection, giving users full control over who can access the broadcast audio signal within the listening environment.

Compact Design with Flexible Connectivity

The Sennheiser BTA1 TV Transmitter combines compact dimensions, versatile connectivity, and practical everyday functionality into a sleek and easy-to-use device. Measuring just 130 x 20 x 56 mm and weighing approximately 100 grams, the transmitter fits discreetly into virtually any home entertainment setup without adding clutter.

Bluetooth Auracast™ transmission provides a stable wireless range of up to 50 metres, ensuring reliable performance even across larger rooms. Support for LC3 codecs and modern Bluetooth profiles helps maintain high-quality audio transmission with excellent efficiency and stability.

The BTA1 can also supply power for charging compatible headphones through its USB output, adding further convenience to daily use. Full support for the Sennheiser Smart Control Plus app on iOS and Android allows users to customise settings and manage features easily from a smartphone or tablet.
