The only small HIC, is the quality of sound in the ear that is not perfect, and there is a slight delay before your message arrives in the ear of your friends (about 1/2 second). But I think it has nothing to do with the headset, but with the Communicatin mode of PS3 that sends a "package" of her to your friends (so you have time to compile and send ).
What is good is that the microphone off when you said nothing, this avoids having a permanent background noise in your ear.
Well, I hope this review is useful;)
