I never talk on live, infact I found my very mangled looking headset stuffed under my sofa just last night. Doubt it will work again and I won't be buying a replacement.
TBH I have nothing to say really. Used it a bit when I played GRAW online as it was useful to discuss what each other was doing but other than that the conversations were always limited to *enter lobby* "Evening lordrobs" "Evening" and that was about it

Had probably 2 chats with randoms and thats it.
On the rare occasion that I did use my mic in the past the joys of living at home meant I used to get "DID YOU SAY SOMETHING?" bellowed to me from the other room from my mum
Also on the subject, there should be a device built into the headsets that electrocutes the ***** that sit there heavy breathing down the mic. Sounds like chuffin Darth Vaders playing you at Texas Hold'em

Those that cough and sniff constantly and don't say a word could do with a dose of electroshock to the noggin too. If you have nothing to say put the begger on MUTE!
