To be realistic, ultrasone's products aren't very well built in the first place. All of their <$500 models share the same crappy build quality and comfort, which is about 90% of their product range. It's not just this case of the ED.8 falling apart and receiving no service for it, but compared to other phones, the lower end products just don't inspire confidence in ultrasone's useful life.
This thread does not affect me in any way, as stuff is jacked up 100-250% here in Aus, so I'd be buying things without warranty. I'm quite meticulous with my gear so stuff breaking has never scared me, and I just wouldn't buy a closed headphone that's over $1500.
I don't want Ultrasone to fall, I just want them to create better products, because the sound of my friend's DJ1 that he bought cheapishly is great for the price, the folding portability and decent looks are also fine. On the other hand, the PRO2500 is open and folds up? That's almost inviting someone to take an open high end phone outside. Completely stupid. If it's not meant for portability, don't make it fold.
Ultrasone as a brand is kind of stupid really. The only phone I see as viable is the DJ1 and perhaps the HFI-780 if you're wanting to take it outside.
