Game-Changer for Music and Gaming? Sennheiser’s BTD 700 Is Here

Sennheiser just rolled out something small that’s going to make a big difference in how wireless audio sounds across your devices. The Sennheiser BTD 700 is a new Bluetooth dongle designed to unlock high-end audio performance in a super compact form.

It’s tiny—just 24mm long and 2.2 grams—but packed with support for the latest Bluetooth 5.4 tech, low-latency Game Mode, aptX Lossless and Adaptive audio, and even Auracast broadcasting. Plug it into a USB-C port (or USB-A with the included adapter), and suddenly your laptop, tablet, or phone is set up for higher fidelity sound than most of them offer out of the box.

As Christian Ern, Sennheiser’s Senior Product Manager, put it, “The BTD 700 makes high-performance wireless audio easy.”

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

At a glance

• This dongle lets you enjoy high-res wireless sound (24-bit/96kHz) on devices that lack built-in aptX support.
• Game Mode delivers audio latency as low as 30ms—ideal for fast-paced action.
• It supports Auracast, letting you share audio with multiple devices at once for group listening or events.

Elevate Every Device’s Audio

If you’ve got a favorite pair of Bluetooth headphones or earbuds and feel like they don’t sound their best on your laptop or tablet, that’s because many devices don’t support premium audio codecs. That’s where the Sennheiser BTD 700 steps in. It adds aptX Lossless and Adaptive codec support, so your music streams in high-resolution quality—up to 24-bit depth and 96 kHz.

It’s fully plug-and-play. Just plug it into any USB-C port (or use the adapter for USB-A), and the device instantly becomes your new audio source. It’s compatible across Android, iOS, iPadOS, Windows, and macOS. Because it’s class-compliant, there’s no software install needed. It works like a flash drive—but for audio.

Even better, this dongle brings premium codec support to headphones that can use it, including popular models in the Sennheiser MOMENTUM and ACCENTUM lines. That means if you already own one of those, you’re set for a serious upgrade in wireless sound performance.

Game, Stream, or Share

It’s also built for low-latency performance, which matters for gamers and video calls. Game Mode pushes latency as low as 30 milliseconds when used with supported headphones. That keeps the action synced up with the visuals—key for shooters, racers, or any fast-paced titles.

There’s also Auracast support. This tech lets you broadcast your audio to multiple Auracast-enabled devices. Imagine hosting an outdoor movie night or a classroom session where everyone gets the audio straight to their own earbuds—no lag, no hassle.

On calls, the dongle’s advanced codecs also make your voice clearer. Compared to standard Bluetooth setups, this gives you more reliable audio for work meetings and video chats.

The Wrap-Up

The Sennheiser BTD 700 hits shelves on June 3rd, 2025, and sells for $59.95 USD or $69.95 CAD. You’ll find it at select Sennheiser retailers and online at sennheiser-hearing.com. For anyone who wants better wireless sound without swapping out their existing gear, this dongle is a smart and simple upgrade.
