My friend has the Incredible and we are trying to locate a corded headset for her. She ordered this headset and this adapter. When plugged in (and the adapter/phone/headset connections were all tight and secure) she could hear me, but there was silence for me. I think it may have to do with the number of bands on the adapter, but I'm not sure. I found this other adapter on Amazon that may work, but of course, no guarantees. Any suggestions from the community? We talk for hours from Indiana to California, so she needed something that wouldn't drain juice and would be comfortable to wear. Thanks for any and all help.
