The Sony wh-1000xm4 headphones are playing a loud, high-pitched “screeching”/”squealing” sound at random when the headphones are in use, causing some users substantial pain. The headphones retail for $350.
Sony appears to be replacing some headphones while they are under warranty, but do not repair or replace headphones that are not under warranty.
Some users have reported experiencing lasting ear pain as a result of the loud noise from the headphones.
Some users have reported that they were able to solve the problem by disassembling the headphones and cleaning the area within the headphone cup, but this solution has not worked universally.
Users whose devices have not been replaced may have a claim for defective design, and other users who have experienced the loud noise may have claims for damages resulting from potential hearing damage as a result of the headphones.
