There's definitely gonna be more on XBL then on PSN simply because the XB comes with headphones. The ones that really annoy me are the douche bags that just want you to hear them talk on the phone, or blast they music through the mike like I want to hear that sh!t. I bought a headset just to tell them all to shut the F#@k up.
Hopefully you can hear other people talking if you don't have a headset connected because I plan to record people like this and make a weekly (maybe monthly) segment on my YouTube called "Scrubs of the Week" I'd include these so called Squeakers as well as ragequitters and trash-talkers. Included with every clip will be the persons PSN in big bold white letters.
I don't really use a mic unless I'm in party chat or in a team game that requires serious cooperation. So, I don't really run into these "squeakers."
To be perfectly honest I've come across more douche bags who are 20+ than 12 year olds.
holy shit, why hasn't this been done??
