Bluetooth doesn't have the bandwith to support anything better. Airpods are as far as you can push it with complete vertical stack control. The magic is in codecs and dynamic switching of them based on whether you are speaking or not.


But we have Bluetooth doing lossless audio. If we can do lossless or 700kbps+ audio then we can spare a bit of that bandwidth for the microphone.


Is it really that hard to increase the bandwidth in 2025 to get mic quality that doesn’t sound awful? Opus can be really efficient at low bitrates AFAIK.


No, bluetooth has enough bandwidth for 990kbps LDAC, so it should be possible to do 128kbps stereo + 64kbps OPUS mono mic.


How does wifi support multiple gigabit now while Bluetooth can’t support a microphone that isn’t horrendous?


In short - BL uses much less energy than WiFi. It's harder to have speed and be battery friendly at same time.
