Yes it does, the only thing I like is that it saves your drafts now. Only positive I've really come across.
Like all headphones it does have it's issues, has a slight upper mid dip(not as bad as the Hawks nor does it have the hole the Elears have) and it does have some 10khz energy, but less than most Beyers. It's on the intimate and dry side. I view it as a better HD 600 as it has a similar sound balance but with a bet less upper mid presence and it's more dynamic and tactile, it's a very addicting headphone imho, especially with the right amp. I absolutely love the DT 1990's mids, they are so musical and addicting, one of the few headphones where I like the mids better than the HD 6xx family, there's something oddly euphoric about it. I am waiting for Senn to release a new headphone in the upper tiers that is a new design. The DT 1990 is a rather robust sounding headphone and the two pads it comes with does change the sound a good amount, so it's really preference which one you will like more.
Yeah, not sure what's going on. I guess it really appeals to some people, many do find something quite pleasing about it. I'll have to listen to it to make a judgment on it. Yeah, the Hawks are actually really resolving and the headphone has a lot of body to it's sound, the mids definitely don't sound thin on the Hawks. Some of the most resolving headphones have some iffy FR responses. Interesting, honestly none of the current bio-cell sounds like bio-cell to me as I heard the original bio-cell first. Have you heard the Sony MDR-Z1R? I actually quite liked the headphone, best thing Sony has released in a long while.
