I've been using a Plantronics 975 Discovery headset on my OG Droid for months without any problems. As soon as I switched to a Rezound, people started telling me that the 975 was picking up background noises that it never did before. Typing, breathing, conversations of people 2 rooms away. I've tried repositioning the headset on my ear. When using the phone directly, these sounds are not transmitted. Has anyone had this problem?
