Input:
I bought these to replace my Sony foldable headphones (MDR-A106) because the foam had completely fallen apart on my Sony pair. The sound with these headphones was absolutely terrible. No bass and it sounded like I was listening to my music in a tin can. So I took off the foam and put it around my Sonys right after and the Sony pair put these Maxwells to absolute shame. Don't buy this.
