I have exactly the same problem as dcalva (dan) as I will quote below. -badearings I have the Motorola MOTOROKR S9-HD and I use it with my iPhone 4. Recently when I started using it, the sound automatically by it self starts beeping and then lowers until you cant hear much. When I try to increase the volume it will not respond to the commands on the headset. Now I cant increase the volume at all. I tried reseting the device, I tried resetting the phone, I have tried everything. Can you help me???Thanks,Dan

open the boom flip. Press and hold both volume buttons and the call button for more than 10 seconds. The indicator light flashes 3 times and then becomes steady lit. The headset is now in pairing mode.

Because of the design of these headsets, over time the wire leading to the mic can wiggle and break loose, which allows you to hear fine, but prevents the listener from hearing you. My bet is that it's the red wire, as it tends to have more pressure placed on it. The dismantle process isn't easy (i'm working on the very same problem at the moment!) but if you'd like to try it and are able to do very fine resoldering I can share my notes with you. Otherwise, you're out of luck and will need to purchase a new headset. Sorry I can't give you better news!

SOURCE: Motorola S9-HD will not turn on or charge

I had this problem as well, and my issue stemmed from a faulty charger that came with my headset. I would suggest trying to charge your headphones with a different cable. I found that I could charge my headphones with the microUSB cable that connects my laptop to my external hard drive.

Motorola blue-tooth devices are mostly meant for Motorola phones. This particular device is restricted to be used by Motorola phones. No matter how hard you try the devices will not pair because they are not compatible.
There are certain blue-tooth devices which are universally acceptable by all types of mobile phones but the MotoRokr T505 as it is dubbed by Motorola is restricted to Motorola phones.
Sorry for any inconveniences.
