audio clarity is poor on bluetooth headsets with iphone 5
I have the Plantronics Voyager Legend and have updated to the latest firmware (Nov.2012). This firmware update was supposed to have fixed the audio distortion and quality issue. However, it has not improved on my headset. I have tried all of the troubleshooting suggestions: resetting network settings on the iPhone and reboothing, deleting the Legend from the iPhone and re pairing, Nothing has worked. Plantronics says that other bluetooth headset brands are also having similar issues. Has anyone found a resolution to the audio quality issue with bluetooth headsets?
