Yeah i've always found that rather strange and unnessacery ..

Whenever I fight people in Tekken with one all I usually hear is background music or them shouting because they just lost (or won but the lost is more common).

Also, on subject, keep in mind in Europe with so many different languages, sometimes it's just as pointless because we don't understand each other. 

I use the mute option all the time. I don't want to deal with are talk to little brats online. lol

Thank God they are only few, the rest I mute...Its so annoying listening to every idiot or kid around the globe when trying to play a game

PS> Thank God for the MUTE button

Because my gaming time is usually beetween 11pm to 2am ;)

  I have a mic for ps3 but I nearly never use it. I didnt have to go out to buy one because its something that came with my cell phone. Its pretty awesome that ps3 is compatible with something like that.  

  People really dont need mics for games though.  In theory, I'm sure it can be helpful but the majority of the time people that have mics are extremely annoying and dont offer anything of value. I'm at the point where if I hear the crackling of someones mic in a game I immediately go to mute them. I'd say 95% of the time its someone that is just going to be aggrivating.

Because no one else does. It felt like talking to a wall then I played Uncharted 2 -.-

I don't use it if other people don't have a mic, and vice versa. Got the official PS Bluetooth hooked up to the USB personally.

No cross game voice chat is one reason. No good bundle with a game at an attractive price is another.

I don't play enough online to make the cost o a mic worth it. I borrow one sometimes  but never seem to talk much anyways.
