As with all Chinese junk, the review is not to be trusted. You need to listen for yourself. I compared them with sony xba-a2, there are no such problems. Pros below: Package. Sound without distortion in the reproducible range. With its cons: Lots of bass, little treble. Of course, this is not koss the plug, but there is no question of any "best under $500($250, $100=)". Ordinary headphones in a beautiful box.
