I think the problem was in the headphones. I found I was having trouble on my phone as well. I contacted Sony support and they had me try a soft reset of the headset, which seems to have restored function. I am still getting bad mic sound on bluetooth, but I think it is just the low quality sound on this thread and not the completely muffled sound I was getting before. I will try reconnecting to the DG80 now and see if it is any better.
