Bluetooth earpiece turns off during call

[RedBarchetta]

First, my specs: I have an HTC Evo 4G LTE, software, firmware is current. I am using a Plantronics M50 earpiece. The problem: I have it in a Sprint car dock while driving and I make a couple calls on my way home from work using my Bluetooth. It started about 2-3 wks ago. I'll start a call and while the phone is ringing on the other end, it goes silent in my ear and I can hear it through the normal ear speaker on the phone (speakerphone doesn't kick on). I have to turn my Bluetooth off then on again to re-establish a connection. Then it stays on through the call. It happens when I answer a call as well. Happens when not in the car dock too. It doesn't do it twice in the same call, after reconnecting the Bluetooth, the call stays connected. I have already unpaired the Bluetooth and did a simulated battery pull (battery is not removable) and hard reset to clear data then pair it up again, but it still does it. I have a feeling that it's not the Bluetooth, but something in the Bluetooth software in my EVOLTE. Anybody experience this and have a solution?

I have this same problem with my samsung galaxy s3. I also use a plantronics m50. Were you ever able to resolve this?
