I picked up one of these headsets because as a PC gamer, I felt that having voice com ability in online games is just an essential part that makes it a lot more fun. As a new PS3 gamer though, I didn't realize that hardly anyone was talking in online games. This was sort of a letdown, but it's nice to have I guess, at least I have the option to start talking.
It's really similar to most of the other bluetooth/wireless headsets out there. Obvious it's a bit more weighty than the wired ones, but it's fairly comfortable when you get it on your ear right and if you don't move around too much. I don't know if I'll keep it on all the time I play, because it is kinda annoying to have on, or maybe that's just my brain being picky.
I did notice it cut out a few times when my cordless phone was ringing. Not sure what that's about.
