This New TV Headphone System Serves Up Lag-Free Audio to Many Pairs at Once

"Auracast is among the most intriguing new audio technologies that you've probably never heard of. Using a new, more efficient type of Bluetooth, it promises lag-free, high-quality sound transmission from up to 100 meters for a limitless number of devices. It has a ton of potential: Someday, we may tap into Auracast broadcasts on our phones in places like airports and gyms to get a private listening session from public TVs, like a cross between Wi-Fi and FM radio."

"That's what makes Sennheiser's new BTA1 TV transmitter so special. This little block is loaded with inputs, designed as a sort of bridge between Auracast and virtually any TV. Where most traditional TV headphone systems use older standards like radio frequencies or a 2.4-GHz signal to send wireless audio to dedicated headsets, the BTA1 opens things up to any Auracast headphones."

"After a week of testing, I came away mostly impressed by the transmitter, moderately underwhelmed by the headphones. Bundled or not, this system shows real promise as a versatile TV headphones setup and a tantalizing introduction to the world of Auracast."

Sennheiser introduces the BTA1, a TV transmitter system that utilizes Auracast, an emerging Bluetooth technology enabling lag-free audio transmission to up to 100 devices from distances up to 100 meters. The transmitter bridges traditional TVs with Auracast-compatible headphones, offering multiple input options and a compact design. Bundled with the midrange HDR 275 headphones, the system provides clear sound and versatile connectivity. However, the included headphones lack noise canceling and feel plasticky, while software performance is sluggish. The transmitter represents a promising introduction to Auracast technology, though compatible headphone options remain limited in the market.
