Ultrasone DJ1 or DJ1 Pro?

So I've finally decided on a model for my first high end headphones. It's taken me a good week to decide, and for my situation these seem to be the best choice for me. Now, from what I've read / seen there's minimal difference between the two. It looks like the following changes were made...

- DJ1 Pro come with removable earcups, along with replacements
- DJ1 Pro are apparently tuned a tad bit better than DJ1
- DJ1 Pro have two cables, with a 3.5 adapter
- DJ1 Pro are slightly larger, and earcups are round rather than oval
- DJ1 Pro have a few goodies, such as improved carrying case etc
- DJ1 Pro have improved radiation reduction... so they say
- DJ1 Pro last difference I noticed was price, obviously

Basically, I would like to hear everyone's opinion on this one. Should I spend the extra $ and get the Pros? Or just go with the DJ1's. One thing I should point out, I have a relatively small head. It's not small, but it's smaller. I'm really looking for comfortability as well.
I'd like to point out one more thing, unfortunately in my situation I have no way of testing either out.

Update, Amazon is the only place I'm willing to purchase from, and the price difference is pretty understandable. I think I'm going to purchase the DJ1 Pro's with 1 day shipping. They'll arrive tomorrow according to the site, and if I'm unhappy I'll probably just return and get DJ1's. Either way, if anyone still has opinions they would be greatly appreciated, seeing as how i'm terribly impatient and would love to read what you guys have to say. I'm hoping to get hyped, who knows I may even have to snort a few lines. Thanks again guys

alright cool. Good point btw, shoot for the best. I just ordered em, should have em tomorrow. Lol, the snort comment was a joke, I was saying i'm so excited I might snort a few to pull an all nighter, and in turn stay hyped until they arrive. Like i said, just a joke. Sorry mods, and sorry kids.

Alright, they arrived. My first impression simply put is... Holy sh*t. These things are so nasty. I can actually hear things in my music, like things I've never heard before. I tried em out in game too, Crysis was a blast with em plugged into my onboard sound. It's an Nforce 780i, so it supports up to 7.1 SS. Man, these things are beastly. Sad thing is. I don't have any additional set ups. No amps etc . Regardless, these things sound great out of the box, and I can't wait until they're burnt in. Though I'm not really sure how the process goes. All in all, thank again guys, I'm glad i made the purchase.
