40mm drivers, 40 ohm impedance, half opened, softskin earpads.
Punchy, clean bass (some others have more subbass, most not).
Slightly recessed midrange (should have a THD peak at 4kHz, I don't hear).
Brilliant highs (sounds more detailed than my lambdas, maybe just pseudo).
Earpads are circumaural und quite deep (more place than others, relatively).
WOW factor (at least for unexperienced).
1500mW power (loadwise).
10 feet cable (comfy).
Lightweight (220gr).
Cheap (20 bucks).
Stylish (imho).
One more.
