they definitely loose spring as time goes on. Mine lost almost 2/3 of their thickness over time. But if you send them back to birkenstock, they'll rebuild them for a fee.
Guys, do you really have to act like a bunch of high school brats just because you don't like what he posted somewhere else? Get over it, he likes ultrasones. There's nothing wrong with posting that. The pile on meme is getting old.
Pictures can very easily lie. It could be pictures of a prototype, it could be pictures of something completely different. I'm not saying it is, I honestly don't care.
If that's the value that's the value. It doesn't surprise me that a well regarded headphone that there were only approximately 200 of ever made has gone up drastically in value. They'll eventually all end up in the hands of collectors as the price goes up.
Watching what you eat gets more important as you get older. When I was 22, I regularly ate 6000 calories + a day, and never gained weight. Now, well...
I don't think he's being an asshat there. I may not agree with his impressions of ultrasone headphones, but saying he things they're flat compared with studio monitors that have been eq'd flat isn't an asshat thing to say.
Offer him less, if he wants to sell it to you he will. Sure, the market is impacted by high water marks, but if he can't find a buyer willing to spend that, he'll get less, or won't sell. It's just a pair of headphones. If they're worth the asking price to you, buy them, if not don't.
What's your agenda? You knew posting internals pictures over there would result in them getting deleted, and now you come over here to talk about it like you're surprised at the reaction.
