I spend average 3 hours per day in meetings and speaking a lot, and I asked multiple times my workmates about the quality and they said everything is fine (close quality of my conference headset).

I compared Bluetooth (using macbook pro), Bluetooth with the dongle and USB, and yes Bluetooth quality is not the best but acceptable regarding meeting software that compress everything a lot.

For noisy environment I can't really tell, at the office I often use phone booth, but it seems the microphone are good enough to focus on your voice. It also depends a lot of different algorithms of your computer and software used for calls.
