I just purchased the subject headset and paired it via bluetooth with my Droid X. The headphones work great for listening to music and when a call comes in I can answer the phone and hear the person on the other end but when I speak to them they cannot hear me. Can anyone tell me if there is a setting that I need to change or something I need to do in order to get the microphone functioning on the headset? Or do I just have a defective headset?
