Left speaker only working intermittently, crackling noise with ANC
Hello good repair-inclined folks,
Recently, my Bose QC35 headphones have developed an annoying fault. At first, I noticed a crackling sound in the left speaker, which is motion-sensitive and linked to active noise cancelling (no ANC, no crackling). Later that day the left speaker kept dropping out.
Has anyone dealt with this? Is the driver shot? Any repair advice would be appreciated.
