On ear, or Over ear?

I have a little home studio and i also do recording/mastering for some local bands here, along with producing my own stuff.
I chose the k701 because they span an extremely wide range of genres. Be careful tho, if you're used to dj headphones with pronounced bass response, the 701 will disappoint you in terms of quantity. In terms of quality, they're IMO far above many high end esoteric headphones, for production. They're flat, and i mean FLAT. Their HF freq response is amongst the best i have ever heard (and believe me, i've heard a LOT of really expensive hifi stuff).
The soundstage is immense, try listening to some live classical recordings, and you'll be blown away.
I use them in concomitance with my monitors for when i have to analyze every little detail my mixes have. But remember you can't replace monitors with headphones. So think about buying some decent monitors along with your sonys, if money's no object.
If it is, well, then the 701's will blow you away big time

Yeah I already have Focal CMS 65 monitors so am covered there, just kind of limited by the room layout of my apartment so having some more detailed headphones is useful.

Plenty of good reasons to use headphones at home for production- most people don't have great monitors and good sound treatment in an ideally setup studio so having headphones as another reference is valuable.

Nor do many people own a home now a days... Townhomes, Apartments.. you just arent going to get away with blasting your Monitors

Well the focals are amazing, you're definitely covered there, so go for the 701/702s . If you're worried about bass, don't be. I somehow manage to get tighter bass on the 701s (where bass is not massively present) than on my 2.2 monitor setup in an -almost- acoustically perfect space, go figure.. The first time i heard them i was completely stoked by how much detail in the higher frequencies these babies can reproduce. Also, they're BY FAR the most comfy headphone i ever tried.

Oh and you should get an amp for those.. they are quite power hungry
