Ultrasone DJ1 PRO - are they worth the effort?

[The DarkSide]

The title says it all,...I'm curious about getting them.

Especially since I'm thinking about getting the BayerDynamic DT770 80 ohm.

So, the DT770 or these???

What gear will you be using with these? The Beyerdynamic, even though it is 80 ohm, still fares better with an amp. The Ultrasone isnt as dependant on an amp to sound good.

I'd avoid S-logic, but thats just my personal opinion.

I have a few amps, and quite a few portable sources. I'm just wondering about the sq. I owned the HFI-780's and I wasn't fond of the bass - are these better???

Maybe, just maybe, I should get the V-MODA Crossfade M-80's??? I hear the sq is FANTASTIC!!!
