General bluetooth headset issue

This falls under the same ideas of audio distortion and stuttering and output from wrong deivce, but I think I found the cause of the issues?

For bluetooth headsets to play games properly, you have to disable its microphone/communications ability and use a seperate microphone because if you don't, it will use handsfree telephony audio to split the bluetooth signal into part microphone data and audio, which results in a distorted lower quality audio output signal. If you try to disable it and use the microphone, it will try to put the bluetooth data on the same bandwidth by stuttering all the audio, creating the stuttering.
Normally games dont have this issue once you just use a seperate microphone for voice input, and all audio output just goes to the headset. In marathon, however, I noticed that, in addition to a voice input device, there is a voice chat audio output device. If you set that vc audio output device to the bluetooth headset, it makes the headset think it is in telephony mode, or something, and the above problems will be created, regardless of if you have a seperate microphone input device. I verified that this was the issue because if I set that voice chat output audio device to my laptops speakers, i will get clean audio from my bluetooth headset, but obviously people talking to me will only output on my laptops speakers, hence the issue with the voice chat output from the wrong device.
Having the audio output channels (or what they are actually called) seperate (the game audio output and the voice chat audio output) makes it like unfeasible to play with a bluethooth headset, which isnt fun.
Sorry if this felt like mansplaining I just hope to help because I really think this game is cool and I really want to experience it in the best way with good audio and I hate my bluethooth headset doing this all the time. Best wishes!
