Pros: Weight, Comfort, Soundstage
Cons: Tone, Fatiguing
I used this out of a USB Pico DAC -> Dynalo (Sheer Audio HA-006+) -> K702 using well ripped FLAC files
I really thought this was going to be better, but I really just do not like these headphones much at all. Probably my biggest complaint is the airyness and tone of the vocals. I also have a pair of Grado HF2 and the HF2 just absolutely completely super duper destroys the K702 in tonality, especially the vocals.
It's also very fatiguing for my ears for some reason, even at quiet-medium listening levels. I've read this is because it has a high frequency spike or something. Oh well. I learned a valuable lesson with these K702, the best and only way to know if a headphone sounds good to you, is to listen to it yourself.
addendum: I suppose this could've been good for me had I a different amp or source or whatever. A Pico DAC -> Dynalo setup is a pretty standard and good setup. To me, a standard dynamic headphone like the K702 is, that doesn't sound good on my setup, is not a headphone worth paying for.
