Bluetooth and internal microphone

[Nebel22]

Hi, I would like to know if it is possible on any android phone to use both a bluetooth or a USB headset and still be able to use the built-in microphone. If it is possible, on which versions of Android?
Thanks in advance.

I sometimes use headphones to watch DroidTV and answer incoming calls using them and the stock Mic.

Could you be more specific please? What headphones are you using? Was it difficult to set up?
Thank you!
