Hi

Background:
I'm really in to music and I use pair of high-end noice cancelling headphones.
I also study psychology and when talking I want to use a headset with a better mic. I read minute changes in voice and so on when reading someone, and I want the person I'm talking to to hear me as if we were in the same room. A one ear handsfree with a noise cancelling mic right next to the corner of your mouth should be the best option, shouldn't it?

Question:
Can I have a pair of BT (wannabe) audiophile headphones for music, switch them off when someone calls (after answering the call and asking them to wait a second), turn my good-mic-headset on and have the conversation?

BT is a 1-to-1 pairing, but at no point is any device coupled to more than one other.

Sincerely yours
