Installation Notes: This is a fiddly repair requiring steady hands, a T6H screwdriver at a 90 degree angle, and other tools. We recommend professional installation if you are not comfortable with small-part headphone repairs.

If you prefer not to repair it yourself, we also offer a Bose Ultra mail-in repair service.
