I was wondering..
I've been familiar with the 3.5mm jacks connected usually to the headpones or earphones straight to the cellphone or to your pc.
But I was surprised when I saw a 3.5mm Jack with three wires inside it..
I was wondering, Which of these ones are positive and which ones are negative?

Thanks for the replies!
:D
