I tested out a Motorola Bluetooth headset that I have used in the past for my mobile. Just wanted to see how it connected with the PS3. It worked, but the results were bad. I get this echo, but I am thinking it's the proximity of the mic and speaker on the headset that's doing that.
May look into getting one of those ones that have a boom at the end of the headphone. You know like the ones those hardcore and Xbox gamers have. Heard from a friend that the headset for the new SOCOM is good and is like the one I described.
As I said above, I may get one of those. Not sure any of you really want to hear me and my excuses when we play HD :P
