I just picked up a pair of DNAs. I have nothing against Monster, Apple, Bose, Coke, or any other corporation. I don't care if enthusiasts think Monsters are fashion accessories. I just want some portable HPs that sound good with my gear, price/value is secondary. I have a set of Audio-Technica M50s/LE for reference. Source is iPhone 5, 15" Macbook Pro retina.
While I enjoy the M50s, they are simply too big to be portable. Too honkin' big to wear around your neck walking around an airport, and the non-detachable, mile-long cable is a tangled mess to deal with.
The DNAs are reasonably comfortable but won't last a marathon (+4h) session. Clamping force is just right for my smallish head. They are lightweight so that when the music moves you, the cans won't fall off your head. I'm digging the short, flat, detachable cable. It can be jacked into either earpiece. Either 3.5mm can be used to share music with a nearby friend. Nice touch. Build quality is plasticky but I'm careful with my stuff so durability is not an issue for me.
I am pleased with the SQ. While I know it isn't flat, I don't prefer a flat FR. It sounds boring. Maybe good for folks who likes music from the pages of Stereophile, but I like my tunes to be more exciting. It tends to be slightly darker, and has less treble extension/openness, than the M50s. But I wouldn't call it muddy. I have had it on for over 2h now, and it is not fatiguing. While I expect that it won't compare to some the cans the enthusiasts rave about here, or to some kilo-buck open-back Beyers, it's good enough that it doesn't distract me from the music as I surf the net, walk the dog, or kill some time on a plane. It's good looking, light, practical. For 200 beans, I'm a happy boy.
(I also bought the Monster Inspiration to try and those are garbage. I might say a few words in an appropriate thread.)
