I'm using it. I haven't had a lot of luck with bluetooth in the past on the PS3. The few I tried would randomly disconnect, or have poor sound quality.
This one has no problems. I could hear people very clearly, and they said they could hear me fine. It does seem a little bulky and LOL at the ear penetration remarks. My ear was a little sore after I played about 3 hours last night, but my guess is as time goes on, that will just go away.
My old PS2 socom mic that's held together with duct tape is going in the drawer for good.
