Quietcomfort 35 (1 series) loud screeching and piercing sound
Anyone experiencing loud screech and piercing sound that was deafening? this happened to me only on the right ear and then it went away after about 7 seconds. it just started happening recently and unexpectedly (about 3 times now).
And then the right ear doesn't work anymore. After reset, clearing all bluetooth, making sure firmware is up date it seems to be fine then unexpectedly destroys your ear again. imagine loud enough it actually hurts. the right ear doesn't work after each episode but i found out that you can turn it off and it works fine with the aux cable. This is weird. Bose is helping trouble shoot now.
