Gunner, The coms are not that great in BF3. My only experience was with OB and Anderson in the lobby and it was bad at times. OB has since removed his 250' headset extension cord and some of the reverb I was getting from him was fixed as of last night.
Apparenlty Dice is looking into fixing it. I wonder if it is with the same fix that is coming in Jan with MW3 coms. Makes me think Sony is getting a software patch ready ( I can wish right?)
When in a game
Start
Squads
scroll down to bottom. There are the VIOP (Voice Over Internet Protocall) preferences.
Chose Team or Squad
When with clan the 3 of us run squad and we can only hear squad members. If you are on team and they are on squad you will not be able to hear the Squad.
So few randoms use mics. I have seen like 3 people this week who are not anderson and OB who use mics. Bummer.
The Xbox allows you to use the voice chat feature through Xbox Live. Apparently you can run it in the background and talk outside the game. I knwo people are using this to talk on Xbox. PSN does not allow you to run the voice chat in the background when in game. SOoooo until Sony changes that (Maybe with PS4?) we will have to rely on what they have for us in game. Sorry!
I bet this game on PC is boss since you can run Ventrilo as the coms.
