My opinion: The main reason I do not use the on board speakers is that I want to hear what the people are hearing. The on board speakers and the Bose do not have the same the same sound; especially the bass.
I love the mic headsets, but I am wearing glasses, and sometimes I star at the music -- and if it is wired the wire is all over the place – and I feel like a man from Mars.

It is another thing to be concerned with. I move to and from the mic depending on what I am doing; they are two different sounds.

Cassp, give it a good try you may love um.

PS, how many people use a mic headset?
