QC35 problem - no sound
I have a pair of QC35's I've been using for the past 3 years.
Today they made a little strange sound and then suddenly there was no sound. I tried rebooting them by turning them off, wait, plugging them in and leaving for a bit and turning them on again many times. With little to no success. Sometimes the ladies voice came on - sometimes only for about 3 seconds. The ANC is on. But the voice is not in either position. I also tried to update them on the Bose website to the latest firmware. No luck.
I've also tried to plug them in with the cable and they work. I think it has something to do with the bluetooth and the voice is gone (it cant connect to my computer n'or phone).
Do you guys have any suggestions for possible causes to this problem?
