If I remember correctly, the bluetooth headset profile (if you require microphone input) is pretty low bandwidth (think gsm quality), which would explain low quality in that case.
Newer Bluetooth variants support higher quality audio without a microphone (A2DP), and that's what you are likely using today unless you are in a call.
As far as interference in the 2.4GHz range, there is not much you can do about it in areas you don't control.

the headset profile is a bit nicer than GSM (higher rates, more advanced codec), though nothing you'd want to listen to music through.

A2DP has been around for awhile. as some other comments mention, there are multiple codecs that can be used. the minimum one is SBC (also used by HSP, at lower rates), which... isn't great.
once you're using aptX/AAC, perceived quality is far more likely to be dominated by the electrical and acoustic aspects of your headphones.
On that topic: why isn't there a way to connect headphones via A2DP and the microphone with HSP? It's rather disappointing that I have headphones with a built in mic, but I can't use the mic while using them as headphones.
Limitation of the particular Bluetooth version (4 vs 5?), needs to use one or the other. Believe it's addressed in a later version, either by a new profile or maybe similar to the solution you suggest. Did a little research into this after going nuts when headphone quality dropped when the mic turned on in a mobile game.
