This is a handset-style smartphone call microphone. It's black and has a retro feel. Compatible with iPhones and smartphones. You can make calls without holding your cell phone or smartphone directly to your head. Includes a 3.5mm plug. *Since it's an earphone jack, iPhones without an earphone jack will require a separate adapter. I received this from an acquaintance, but I haven't used it and it's been stored at home. Please understand that this item has been stored at home.
