The listing, 3.5mm dual jack headphone/microphone has ended.
This is a very easy to use microphone/mono headphone device. It hooks into any standard 3.5mm jack. No software needed. I don't think I ever used this but did wipe it down with alcohol just in case. Has a SUPER long cord giving you lots of room to move around. I have two of these and have used the other one on YIM and a variety of chat applications that have audio options. This is very versatile.
