Audio connector-Tablet/Slate PCs
Comes in two variants. 2.5 mm and 3.5 mm. This is a connector for plugging in a standard pair of music headphones. It can support stereo and/or microphone, depending on the number of separate connector rings on the jack. Headphones supplied with mobile phones usually have a mic somewhere along the cable and a remote button that allows for managing calls without using the phone.
