Hello,
As the thread says my Sony WI-C310-re Bluetooth headphones lost 70% volume. I have them for 5 months . After one month one headphone lost the volume. Didn't bother much, as the other one was OK. Then several days ago the 2-nd one collapsed. I can only hear about 30% volume, which is ok only in perfect silence environment. Is there a driver or something to make the volume raise up again?
