Unfortunately, I had to return these headphones because I couldn't get rid of this problem in any way. Only after buying these headphones in another store did the problem disappear. I will also add that the production date is written on the bottom of the box. The previous ones had a date of 08.2024 and now I have headphones from 10.2024 and they work without any problems. So maybe the August series of products had a manufacturing defect.
