I have the Bose Quietcomfort 25's and they have been great. Until recently when I went to pair them and turn them on. They dont pair, they are now listed as CSR-bc7 in my BT devices and when I turn them on the BT light flashes red. They also dont say anything through the ear piece when they are getting powered on or pairing like before. Not dropped or damaged between when they worked and didnt. It was on a flight, they worked on the way there and not on the way back. I have tired powering off and back on and charging the battery again with no luck.
Any idea why this would randomly happen and any steps to fix?
