It would also be helpful if Apple were to actually make a 3.5 mm male/female adapter like the one that I thought I was buying! Full marks, however, for producing this useful piece of equipment, even if it is of no use to me. …More

This is the ONLY adapter that will allow you to use your regular cell phone wired hands free headsets with the iPhone. It also allows you to use your house phone wired headset with the iPhone. Those use the 2.5 mm pin, and this adapter plugs that into the 3.5 mm that the iPhone uses. But BEWARE, this is the ONLY adapter that will work in the iPhone jack.
