I just got a "like-mint" pair of DT770 Premium 600 ohm headphones in the mail today. I am loving everything I'm hearing so far, they're pretty balanced as far as I can tell which was not my experience when I owned the DT770 Pro 80 ohm. I'm just curious of how big the difference is between these and the newer T70 (not T70p). I love the way the T70 looks and I know that they have different drivers. I just need to know if purchasing a pair of those in the future would be a dumb move or not. 
 
So can anyone who's heard both give me a good description of their differences? 
 
Thanks!
