Hello! I am kinda new to the whole headphone business and mostly have just been using whatever i find. I am in need of some headphones that are in the mid 100s range or lower. I mainly listen to dubstep, drum and bass, house, and hard rock. I love bass but don't want to overpower everything else. I also need a portable amp that would be good with the suggested headphones. My price limit for the amp is about $30 max. Any suggestions would be nice thanks! Also the headphones I have been looking at are the Audio-Technica ATH M-50's and I have been looking at the Fiio E6 Headphone Amplifier for them, would that be a good combination for me to get, knowing my music preferences?
