thank you Linux for giving a damn about Bluetooth headphones

For context, LDAC is one of the few wireless audio codecs stamped Hi-Res by the Japan Audio Society and its encoder is open source since Android 8, so you can see just how long Windows is sleeping on this. I'm excited about the incoming next gen called LC3plus, my next pair is definitely gonna have that.

I think that might be the codecs' fault. At least for me, my headphones sound terrible in headset mode on all the devices I've tried, regardless of whether they're running Linux, MacOS, iOS, or Android.

It's the profile, not the codec. The codec just defines how the audio is compressed, the profile defines all the parameters around that like duplex for microphones.

A2DP is the profile used for music by everything, HFP is the profile that is used for calling by most things nowadays.
