The Sennheiser brand today announces the BTD 700, a high-performance Bluetooth® dongle designed to unleash the full potential of your wireless headphones and earbuds. Whether you’re immersed in work or play, the BTD 700 enables the best aptX™ audio codecs, Auracast™, and low-latency gaming possibilities via a single plug-and-play solution.
Packing a punch
Weighing in at just 2.2 grams and measuring only 24mm long, the BTD 700 is smaller than most flash drives, yet packs a high-tech punch for streaming, gaming, and voice communication. With a single USB-C connection, it’s an effortless way to upgrade the native wireless audio performance of laptops, mobile phones and tablets. An included type -C to -A adapter leaves no device behind, easily improving the untethered audio capabilities of desktop workstations and laptops.
“The BTD 700 makes high-performance wireless audio easy,” says Christian Ern, Sennheiser Senior Product Manager, “This all-in-one unlocks sound quality that rivals wired connections—even adding cutting-edge Bluetooth functionality to PCs and mobile devices missing these newer audio features.”
High-definition happiness
The BTD 700 enables the use of aptX Lossless and aptX Adaptive codecs for reliable, high-definition wireless audio up to a 24-bit depth at 96 kHz. Music lovers can explore their favorites on a deeper level using their aptX-enabled earbuds, headphones and speakers by using the dongle to supercharge their digital audio source. Headphones such as the best-selling Sennheiser MOMENTUM series and select models from the ACCENTUM series are already equipped to support high-definition aptX codecs.
Plug and play
As a class-compliant audio device, the BTD 700 can bypass the native audio output on practically any Android, iOS/iPad OS, Windows, and MacOS device, as easily as inserting a flash drive. Thanks to Bluetooth 5.4, the BTD 700 use cases are limited only by the imagination: set up a portable Auracast broadcast for outdoor movie nights, stream your all-time favorite album with incredible fidelity, or make a day’s worth of crystal-clear conference calls on a more comfortable pair of headphones like the Sennheiser MOMENTUM 4.
Key Features:
- High-definition audio codecs for Bluetooth sound without compromise (up to 24-bit/96 kHz)—ideal for adding aptX™ Adaptive and aptX™ Lossless streaming capability to music, movies, and games—even on devices lacking native aptX support
- Dedicated Game Mode delivers audio latency as low as 30 milliseconds on supported headphones, keeping sound in sync with fast-paced visual action
- Auracast™ support lets you share audio to multiple Auracast-enabled audio devices—perfect for broadcasting entertainment and educational content
- Superior voice quality for reliably clearer calls and video chats compared to basic codecs

The BTD 700 begins shipping June 3rd, 2025 from select Sennheiser retailers and sennheiser-hearing.com, with an MSRP of $59.95 USD / $69.95 CAD.
