isn't the ultrasone pro 900 priced at 450$?   I would suggest getting the beyerdynamic pro dt770 (get 80ohm version if you don't have an amp)

thanks alot for the guide !   in the dt770 there is some kind of cotton ring, going around some plastic on the driver, I thought removing it would fix the rattling bass, which it seems like it did. What purpose does the cotton ring serve?

Kind of have the same issue, but this could be because I have no soundcard or amp(yet)?  (tried boosting bass from onboard soundcard, gave a nice boost but all mids and highs almost dissappeared?)

I'm quite happy about my dt770 80 ohm from beyerdynamic, even tho I don't have an amp.   Plenty of bass

I have settled on the beyerdynamic pro dt770 80 ohm as my new headphones   Now I'm not an audiophile and I know little about amps and such, but what I do know, is that I need an portable amp for the cans   External USB connection for my laptop and below 100€   I've been looking at...
