I have had the Bose Quiet Comfort 15 headphones for years now, and love them. I have had no issues but they suddenly started making a loud clicking sound today. I checked the cable, i replaced the battery. What could this be? Please help.
Thanks for reaching out. I am sorry to hear that your QuietComfort 15 headphones are no longer working.
