I'm having some totally inexplicable trouble with a pair of Sennheiser MM200 Bluetooth headphones I just picked up. When I first got them set up, they paired just fine with my Moto Droid (latest firmware, 2.0.1). I was able to listen to music great, talk on the phone, etc., for a few hours. Then for no reason they became disconnected. I checked the bluetooth status and it said they were "Paired but not connected". I tried connecting, but it would simply say "Could not connect". So, I unpaired them and started the headphones up on pairing mode again. Now, the Droid can't even detect them, at all. This went on permanently. I restarted the Droid, pulled the battery, turned bluetooth on and off, paired it to another bluetooth device, I even reformatted the damn thing! STILL can't see my MM200 headset! What's worse is that my wife's BlackBerry Storm can see them and pair with them just fine! Every time. But to my Droid, they have become completely invisible. Anyone run into this, or have any ideas?
