JigpoI get backround noise when listening. Right now I'm hearing a podcast from a website and when I pause I get the backround noise after some seconds the noise drops and everything is silent. I would say it is more of a source problem rather a IEMs problem. I also got this through different kinds of music formats. mp3's were sometimes "noisy" and flac's were crisp clear so far. Maybe you need different earbud pieces? I only tried them for a small amount of time (because I would like to trade for an M6 Pro if someone would want) and only the earbuds that were already on them.
