But they are really comfortable, how would I get them to fit?

I was wondering if and how you can fit the xb series earpads on the pro 900s.

Ipod-rsa sr 71b-ultrasone pro 900

Ipod-amp-headphones

I have heard that the black dragon moon-audio cable does this well. Are there any other balanced cables better than that, for what I'm looking for and price?

Even if my budget goes up to $300, the fiio e11 will give me the hardest hitting bass?

I have the ultrasone pro 900 and am looking for a portable amp that will make its bass unmatchable. I listen to mostly dubstep, if that helps. I am thinking, maybe the digizoid zo2? So if you know of a portable headphone amp that produces the most impact bass then let me know. :)

I am a huge bass head and am looking for headphones with the MOST bass, not just good bass. I've heard that these are my best bet, so now I am wondering which is the bass king! When I say bass I mean impact/bass that you can physically feel. I listen to mostly dubstep and rock, if that helps. If...

So the Sony 1000's have more impact bass than the ultrasone pro 900's!?

Like impact bass, pounding bass that you can feel. Some other ones that I've heard of are the Sony mdr xb series, beyers, and denon 2000's and the monster turbines.

I am just looking for headphones with the most bass, but not just outrageously expensive. I love my dubstep. I think what in looking for is the ultrasone pro 900??
