I've read here for a while and yesterday I found what I feel like to be an amazing deal, but I figured I would actually post and get some input.
Yesterday I was browsing my local Craigslist and I saw someone had a pair of Beyerdynamic DT 880's for sale, for $100. I thought that was a pretty great deal considering the prices on Amazon, some mentions here of them being great headphones, etc. So I went and picked them up from the guy and they do indeed sound great; I went from a pair of Sony MDR-V6's to these and they are some great headphones.
What surprised me is that if the pictures on Amazon are to be believed, these are the "Premium" line of DT 880 as opposed to the "Pro," as they look like the Premiums on Amazon. I BELIEVE they are the 250 ohm version as I have to turn them up higher to be able to hear them at the same volume as the V6's on my iPad, but I still hear them totally fine. I can't seem to find another way to find out which version 32/250 they are, but I would have to imagine that if they were the 32 ohm version, I could have them at a pretty low volume and hear them easily, yes?
Anyway, I just wanted to get an opinion or two on the deal that I found; from what I've read online I'm not sure I would ever find a better deal but I just wanted to get the thoughts of the experts. I've used them on my PC with my Titanium HD sound card and on my Onkyo amp in the living room and they just sound fantastic.
