Sennheiser BTD 700: key features and pricing
The BTD 700 is Bluetooth 5.4 with Auracast transmission, aptX Adaptive and aptX Lossless. It's a class-compliant USB audio device that should work happily with a huge variety of hardware.
The dongle can't upgrade your accessories – if your headphones don't support aptX Lossless or aptX Adaptive, it can't stream to them with those codecs.
The presence of Auracast is really useful, because that enables you to stream to multiple devices simultaneously (provided they're Auracast-compatible, of course). That means your laptop or other device can become a home streaming hub, streaming to multiple compatible speakers or headphones.
It's particularly interesting for Apple owners: Apple hardware such as iPhones and iPads don't support aptX Adaptive or Lossless, so you can't get the best wireless audio quality from them and your high-quality Apple Music subscription. With the BTD 700, you can.
