Question about PS3 Headset

[gafee2001]

So I'm want to get a wireless headset for my Ps3 so I can play CoD online. However, I don't really know too much about this sort of thing and I have a few questions.

1. Other than the official ps3 headset, does anyone have a suggestion for a good bluetooth headset I can use for this purpose? Less expensive is preferred, but functionality should not be jeopardized.

2. Is there anyway to have one set up such that I can hear the audio from my game without my tv speakers actually making the sound? I would like it so that my sound can only be heard by me and will not bother others. Again, a bluetooth microphone would be nice so that I can use it for online play as well.

Thanks for any help.
