I have bought a new headset that has a 3-pin audio jack port. The cable that came with it has 3-pin audio jack 3.5 (I think its also called AUX?) on both sides. Would it be safe to plug it into 4-pin audio port in the laptop or the phone?
EDIT: It is a stereo headphone (output) with a mic (input). It works both via Bluetooth as well as a 3-pin audio jack cable.
