I just received a pair from a friend's sound shop.
I compare the DXB-03 with the ATH M50.
The one thing that suprised me is that the DXBs are on the ear style. All the promo pics make them seem larger than they already are.
Regardless of that the wires are detachable (and feature a neat microphone) but flimsy. The DD headphones are obviously made for listening from portable music devices and phones.
I referenced two tracks while listening to the two sets of cans. A track from the ACM Gospel Choir, Joyful Joyful and a track from The Bloody Beetroots, Rombo.
The most striking difference between the two aside from aesthetics and fit was the pronounced midbass response from my cherry set of DXBs. As someone who refuses to listen to Beats headphones, I would imagine that the DDs are somewhere inbetween the response of the Beats and the M50s. The response was noticably different and nearly "sloppy" versus the M50s more balanced/neutral low end response. It's going to be interesting to hear what happens to the DXBs when I spend more time with them after a break in period. Something tells me that they won't mellow out. "Deep Bass Response, Wide Soundstage, Clear Musical Details." Deep bass response meaning a boosted bottom end through watever means. A wide sounstage meaning from ear to ear, sure.
What I came away with from the DXBs is that it was like listening to a car stereo with the bass boost on versus the M50s with a flat EQ. The DXBs upper end response could be seen as nearly equal to the M50s but certainly not better.
Now, are the DXBs worth the price that MSRP asks? Not hardly IMHO. They should at maximum be $75-$100. I'd be loathe to spend anything over $100 for the DXBs honestly. With all the trim work, I feel that something in the actual response was missed in the original design. Are they bad? No, not exactly. They're just not what I'd expect out of something that is on the same price level as the over the ear ATH M50s.
