What exactly does the BTD 700 do that my laptop or phone doesn't already?

It bypasses your device's internal Bluetooth stack to deliver higher-quality, lower-latency audio using aptX Adaptive, aptX Lossless, & Auracast. Most built-in Bluetooth chips support only SBC or AAC, which limits fidelity & robustness of the signal.

How much better is the sound with aptX Lossless?

If you're using compatible headphones, you'll get bit-perfect 16-bit/44.1 kHz audio — essentially CD quality over Bluetooth. That means fuller dynamics, richer detail, and no perceptible compression artifacts compared to standard SBC.

Can I use the BTD 700 with any Bluetooth headphones or earbuds?

Yes, but you'll only benefit from aptX features if your headphones support them. If not, the dongle will fall back to SBC or AAC.

Can I share audio with others using the BTD 700?

Yes. Thanks to Auracast technology, you can broadcast audio from a single source to multiple Bluetooth headphones — perfect for shared watching or listening experiences.

Can I switch between devices without re-pairing?

Yes. You can move between PCs, Macs, phones, or consoles without needing to re-pair your headphones. The BTD 700 will remember the last device you paired to it. Pairing a new device will make the latest device the default connection when on.
