Pros: Comfortable, Punchy and tight bass
Cons: Scratches easily, Veiled Mids and Trebles due to sheer amount of bass
I'll come back and put a full review up, suffice to say these have a lot of bass, coming from the XBA line. They are by far the neatest looking cans that Sony's released, but fragile indeed, as the cups scratch easily. In fact, this would be the first set of headphones that I have scratched, and I've had a lot of headphones in my time. But unlike most celeb endorsed headphones, you can do single ear monitoring. So for real DJs that spins the vinyl and must match up the beats, I think these will work quite well as its presentation emphasizes the bass and the beat.
Lots of bass up front, but very tight and punch, and doesn't really get messy and flabby unless you EQ your source to massive bass levels. However, in all of the bass the midrange sounds disappears into the background. There's plenty of treble details to pick up, but again, it gets lost with the overwhelming bass, relatively speaking. Its presentation is very much a check shaped presentation, extra emphasis sub 250Hz, and a curious notch around 3kHz that your EQ may or may not be able to handle.
The large earpads are quite comfortable but gets very hot in short time. It's advantageous if you're north of Arctic circle or do not like Active Noise Canceling. It does isolate quite nicely. However, the large earpads trap heat like no other.
For the street $100 (may have to wait for a sale and/or coupons), it's better than most other celeb endorsed headphones, which also tend to go with the check shaped presentation. But your money is probably better spent elsewhere.
