I purchased Sony's MDR-XB950AP headphones a few days ago and 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. No matter how I tried to tweak the bass, I just couldn't get to where I was enjoying what I was listening to. Since I use my headphones for a variety of media: gaming, movies and music, so it's important to me that the headphones sound great while consuming these formats.
Needless to say, I sent them back. I guess, for now, I'll stick with my Philips SHP 8900 cans.
