Today I was supposed to meet a very "motivated" buyer in Anaheim Hills. Waited for the dude for 45 min, called him twice (didn't pick up), and in the end gave up on him... I'm so keeping my DT990s! I'll call it the fun-phone, or maybe my reminder.

Heh, that's my neck of the woods. Thinking about selling my DT990s as well.

i forgot about these. they defiantly look bright. i can understand ''bit'' of a peak from 14k to around 18k with little slight dip at 20k to help headphone achieve good air response, but i think bump from around 8k-10k is where i think i would find annoyance and should be dipped a bit there in that range to sound less sibilant/bright with certain female vocals and most cymbals/hi-hats.

the CSD graphs look good though.

One thing about the DT990 is that while very bright, I do not experience sibilant issues at all. Really the only problem I could find in my listening sessions was brightness. I have not tried the Tesla line, but from what I've read, it seems I'm not missing much in terms of quality.

you could be right. never heard them myself so i can't say. just some headphones is a problem i meant and was just saying. didn't mean to seem to indicate the 990's are. my fault if i did.

With any luck, the DT990 will be given the boot and be replaced by the T90, just like they did to the DT770 and the T70. Go Tesla! 

Are these measurements based on the 250 ohm Premium or the 250 ohm Pro lines?
