I have K514 mkii version. They are very comfy and design is good too, but the sound is lacking.
It's spacious and clear, but there is no "pressure" to the sound. You don't really feel the soul of the music.
I'd recommend it for movies and gaming, but not for music. I think k514's almost total lack of bass gets to me.
Even if you compare them to something like AD700, they will fall short on almost every aspect.
I'd rather "compare" them to laptop speakers instead: you hear everything but it's not really musical, so to speak.
