it is a single pin or double pin?

It's a single pin headphone, that can be connected to most of the mobile & laptops. Plus this particular model comes with at dual pin converter. So if you want to connect this head set to you system that as separate Microphone & Speaker pin.All you need to do is,1) Connect the Converter pin provided with the headset to it2) Now the converter will have two ends that can be connected to Speaker & Mic separately.RegardsBhavik
