i'm looking to spend 200-300 dollars for a new pair of headphones. i'm sorta a rookie when it comes to high end audio reproduction, but i know what i want. i really love listening to music with lots of bass. my favorite type of music is electronica, especially house, trance, drum and bass, and dubstep. i don't have a sound card, and i don't have an amp. if anyone could recommend a starting point, i would be very appreciative!
