haha... you make it sound like it's a bad thing, though i hope it's not. I just appreciate the bass because all this while i've been on the crappy stock iphone4 ones, and for my laptop i use a Logitech H330 USB headset, cus i only have one audio port, so can't use those headsets with 2 separate audio/mic jacks.
The added bass is a lot for my current s500 setup, but it's not overpowering that would make you nauseous or distort the music, so i'm happy for now! I listen to a variety of music, from hardstyle, trance, hiphop, rnb, jazz, rock, alternative, classical sometimes as well if im in the mood, and it makes it so much better for watching movies with awesome surround sounds, makes the action so much more surreal, alive!
