I have had my LG HBM-760 for 3 months. This last week it began forcing the calls back to my handset (VX 5500). The handset says it is still connected to the device, the device is still on (flashing) and, if I put the device back into discovery mode (hold the power button for a few seconds), it reconnects to the headphone for 2 - 3 minutes before forcing the call to the handset again. I do go between two phones with this headphone, but I disable the bluetooth on the phone that is not in use and have not experienced this with the other phone.
