Pros: very accurate response, tight well controlled bass, excellent midrange, and vocals, and bright, but not harsh highs
Cons: while seemingly solid, certain parts of the headband seem flimsy
The headphones come in a relatively plain, well packed box with a screw on stereo jack to mini jack adapter. No frills, just basic.
The DTX-910 is a smaller over the ear headphone with all plastic housing, and comfy velour ear pads. They adjust with plastic slider slips outward, which seem kind of flimsy, the only con to these headphones really. The cable is about 9 foot long, terminates into a gold connector, and is thick, like transatlantic cable thick, very sturdy feeling, including the junction into the left ear cup. The DTX-910 fits snug, but not vice clamping, and the earpads breathe well so the ears, and head dont get hot. The headband has a thin pad of velour padding that works well.
Onto sound. These things really wowed me. the bass can go low, and deep. It's silky smooth like a deep dark chocolate, same with the mids, they just flow. The highs are sparkly, and bright, but not harsh. Vocal control is amazing, best Ive heard so far, esp for female vocals. The sound stage is wide, and clear, with excellent instrument separation, and depth. Jurassic Park sounded amazing on them without the hollow sounding voices that many headphones cause. Plus being they can be driven very well from a ipod, or iphone without a amp. Amping of course helps with motor unit control but it's not required. Sound of course leaks out being a open back, and some sound comes in, however they isolate outside noise much better than I imagined they would.
The Beyerdynamic DTX-910 is a excellent choice for a low cost, excellent accurate headphone, with deep lows, perfect vocals, and good highs. The thick cord may inhibit portability tho, and also use good recordings with them, because they WILL make every flaw well known. Very unforgiving for low grade, and crappy music.
