Joe pretty much covered the needed info. I would only add that the cheap headphones that we get with most cell phones with a headphone jack are the “three-ring” type that Joe mentioned as they frequently serve as both a headphone and mic when speaking on the phone.

Just because you see a 1/8” hole for an audio plug, it might be any one of a number of plugs. If you look at the plug, and count the number of metal rings (not counting the tip): 1: mono audio 2: stereo audio 3: stereo + microphone So I have a headset that has this last plug. It will either work as stereo headphones, but if I plug it into a port of the correct type, the microphone works, too. You can get adaptors in either direction to either allow you to use a two-plug headset in the single port device (that supports microphone + stereo out on the same plug), or to use a single plug headset in a device that requires two plugs You might want to ask your co-workers if anyone has a headset with this connection that you could borrow to test with. Otherwise, if you have a decent computer / electronics store in your area, as it’s a laptop you could take it to them and ask to test their headsets. -Joe
