Sennheiser BTA1 Bluetooth Wireless Headphone Transmitter
Ever tried to relax and watch some TV with wireless headphones? Maybe you’re trying not to disturb others, only to get laggy audio or headphones that refuse to pair with the TV. The Sennheiser BTA1 TV Transmitter puts an end to all that. Just plug this little box into your TV for crisp, outstanding Bluetooth audio with your paired Auracast™ headphones. The sync is spot-on, too, thanks to the latest Bluetooth LE codecs and very low latency. Want clearer dialog? Turn on Speech Clarity. Craving a cinematic feel? Virtual Surround Sound has you covered. It’s quick to set up and the companion app makes customization easy.
Hear every word—at the volume and clarity you choose
Using headphones to watch TV is all about getting your own personal sound. With the transmitter, you can adjust your headphone volume independently of your TV’s speakers. Speech Clarity boosts voices and makes them clearer, so dialog is easier to understand, while Virtual Surround Sound puts you right in the middle of the action. And when things get loud? Normalize Volume automatically smooths out volume spikes—so you don’t have to ride the volume control. It even tones down those crazy-loud ads for things you never wanted.
Effortless setup—yes, really
The transmitter offers HDMI, USB, optical, and analog ports. Optical and analog cables as well as a USB cable are included for compatibility with nearly any TV right out of the box. We did thorough user testing to make sure the experience is dead simple. Setup guides walk you right through it. Just plug in the transmitter, pair your Auracast™ headphones, and—voila—you’re connected. You don’t even need to select the input source. The transmitter does it for you.
One broadcast, many listeners
Want to watch your favorite show with family or friends? Maybe you’re hosting an event at a school or nursing home. No problem. The new Bluetooth Auracast™ broadcast feature streams to an unlimited number of Auracast™ headphones. It’s like an old-school radio transmission, but smarter. With Auracast™ headphones, everyone can choose their
BTA1 TV Transmitter own volume and settings. Meanwhile, the TV speakers can stay on for everyone else. People are free to roam about, too: The transmitter broadcasts high-quality, near-lossless audio up to 50 meters. It also works with AV receivers, radios, or any source with an audio output.
