This product is marketed as a Logitech H110/111 headset. These are two very different headsets. I don't quite understand how a seller thinks they can sell two completely different products as one product. If you plan to use it with a computer and want to use the microphone, DO NOT buy this item. You will only spend money. This is actually a H111 headset with ONE jack. This means you cannot use the microphone. Sound will work very well, but without speaking. The seller must refuse the H110 unless they plan to ship headsets with a DUAL connector. you should be ashamed of yourself.
