This is a great piece of kit and isn't just restricted to your PS3. It's connectable to your laptop, desktop too.
Sound is crystal clear - It really stands out playing the Call of Duty games and to really get a feel of how good these really are, I suggest you load up Resistance 3 and play that! Very, very impressive. Lightweight and have a modern, stylish look.
There are a few down sides though. If you are used to any other blue tooth headset and like the sound of your own voice when talking on PS3, these really aren't for you. The mic attachment also feels slightly flimsy.
Overall, for sound and quality, I would give a 5/5.
For build, probably a 4/5.
Compare these to some of the Turtle Beaches, these are great value for money
