Headphones: Shure SRH940 or Ultrasone or other?

Hello everyone.

My home headphones are on their last breath and I'm looking to replace those at home with the ones I use every day, Shure's SRH 440. I love my 440s. For the price they have been great. Love the mids produced by them and since I don't really love bassy headphones that much, I feel these were a great buy. So great in fact that I use them for more than 5 hours EVERY WEEK DAY (at work).

I have had Grados SR60's, 80's (they have been great too, but I love close back phones), Senns HD280, etc. so now I'm looking for an upgrade of the SRH440s to use while I work (i.e. every week day) while the 440s stay at home at the computer...

Now, budget is $300 down...

I noticed that Shure made these new cans as an update to the 840s. They look great, comes with 2 detachable cables, extra cups and a good-looking case. I was about to budge but:

1) Haven't heard anything about them
2) Should I instead go with the cheaper 840s?
3) Someone mentioned Ultrasone to me and their cans look great and have read good reviews...

I guess question is, should I stay with Shure and buy their new cans? Or are there better cans at this price range??


Thanks

Sooo... no headphones guys/gals here!?

Thanks!
