So I have recently purchased a pair of Ultrasone Pro 900, and I've noticed that a lot of people have modified the stock pads.  Since Ultrasone doesn't offer any good replacement pads (I don't wanna spend $30 + shipping on pleather pads), I need to strip off the spare pads and make my own.
 
Anyways, there are few that I found online:
 
Beyerdynamic Gel pads for DT770/990 - $37
Beyerdynamic EDT 990S softskin ear pads for DT770 or DT990 - $30
Beyerdynamic T5p replacement pads - $200
J$ Denon Lambskin pads - $70
J$ Beyer Lambskin pads - $58
Grado L-cush - $20
Pioneer HDJ-2000 ear pads - $20
 
Also if someone can show me where to get Sony XB700 pads for cheap that'll be awesome (or place to get any of the above for cheaper).
 
Does anybody know how compatible any of the pads above will be on Pro 900's?  If I remember correctly, I think somebody said that Denon AH-D2/5/7k's and Beyerdynamic DT770/880/990/T1/T5p all have same dimension of the ear cups.  I don't have too much money and if I try one of these pads I will write a review (except for J$ Denons because there are plenty already) about it so I'd appreciate it if someone could throw me some hints or tips.
 
Thank you in advance!
