I have a Motorola Droid and just purchased a Samsung WEP870 for use with the Droid. I can hear phone calls perfectly, but I cannot hear any media.
Let me explain - The headset is selected for phone and media audio, and the audio is obviously going to the headset, but all that I hear are "beats" of the audio every half second, or so. I hear what I can only describe as a short pulse of the audio each half-second. Media volume is maxed, and I do not see anything else that could be changed. This happens with Pandora and the NPR audio apps. I don't have any MP3s loaded, so I have not tried them. Maybe I am missing something in the phone settings?
