If you plug in headphones with a mic (ex: apple headphones) you can talk. All there is too it!
Does the ps3 blue tooth mic worth with the vita?
I thought it had a mic built in
Yeah well that's the thing I thought it had a built in mic. I was trying to avoid the whole headphones thing. It is enabled btw in the home button menu.
You should be good to go then. No external mic needed.
