JoostMeij my headphones was doing it on previous firmware versions, for some reason.
Just got another one email from the support, they started talking something about ANC quality, which was no the case.
Anyway enough for me. I’ll count that as wasted $300. Posted fair reviews on few price aggregators, soon will send my headphones to a big youtube channel who have lab equipment for testing headphones.
This was my first and last Nothing product. F this company.
