This Beyer fits the budget, but I might also like to know more about the Ultrasone (Which one is better?)
There's no difference between the two impedances. You're simply given the option to have a different impedance so that you can match it better to various amplifiers based on your source gear. They're the same headphone, they simply have impedance options. One is not better or inferior. The same is true for all the DT series by Beyer. People say they hear differences, but what they're hearing is the difference in matching impedance loads to an amplifier and how the amplifier behaves and controls the driver, rather than the actual headphone itself being "different" (which it is not). Higher impedance does not mean higher quality at all. The 250ohm version is going to need slightly more amplification than the 80ohm version. Both are very easy to drive though, and I simply suggest you get which ever is the least expensive for you.
Beyer comfort in the DT series and T series are legendary. Simply one of the top series for comfort.
Ultrasone is not better; it's a different flavor, different signature. They have a house sound that is unique to them, and it's rather love or hate people seem to find. I tend to not like Ultrasone house sound. Ultrasone likes to spike treble pretty harshly. They're great headphones, built well, and some are sonically great (HFI780 and PRO750). Good accessories, detachable cables, carry cases, etc. But you have to be ok with really spiked treble (brighter than Beyers in general).
Between a Beyer and an Ultrasone, at least in my experience so far, I'm always going with the Beyer. But that's just my preference.
