Ask HN: When will I be able to have “duplex” good quality audio over Bluetooth?
In the current year of the lord 2020, I still get horrible playback audio quality when the microphone on my bluetooth headset is active. E.g, listening to music while being in a muted Skype-call or something.
This has been an issue for as long as I have used Bluetooth products.
Will this ever get fixed? What's the problem? Surely there is enough bandwidth over Bluetooth to fit say 128 kbit/s audio in both directions?
Or does it actually work with some devices?
- mkarliner 6y agoHigh quality audio over Bluetooth is carried by a mechanism called a2dp, which can go in either direction. However, on Android at least, while it can act as an a2dp source, it does not have a corresponding a2dp sink. Bottom line, it's possible, but not with the current Android
- filleokus 6y agoThe same on all recent iOS/Mac devices I've tested. Dosen't work on my new work Thinkpad either. Does the headset need to support bidirectional a2dp also somehow?
- mkarliner 6y agoAbsolutely. I'm working on this at the moment, using a raspberry pi, and that does support 2 way a2dp, it still won't work until Apple and Android support it.
