I purchased Sony's MDR-XB950AP headphones a few days ago. I think I should have paid more attention to the model number, because the XB means extra bass. Sony isn't messing around here, they've tweaked the bass on these cans to an extreme. While playing Fallout 4 the bass made walking in power armor sound like I was a 30 foot robot. Regardless whether I was listening to music, or watching videos and regardless of which media player I was using, I couldn't adjust the bass to a satisfactory level.
Needless to say, I sent them back. I guess, for now, I'll stick with my Philips SHP 8900 cans.
