I'd just like to throw my take on these cans again, after having more time with them, and I have to say these are absolutely Wonderful for some genres, while it ends up ruining others.
I find this has a good low-end kick for EDM and the like, as well as hip-hop instrumentals and such, but when it comes to Metal, it does end up sounding a little off, and in my opinion, makes it sound bad.
When I listen to Hip hop the main focus for me is the drums. The bass, the hi-hat, the cymbals, they have to sound right and balanced. Ain't no hip-hop fan want to listen to hi-hats without no bass. Thus with the 65th I personally find a great balance with that aspect. With D&B and similar genre's, the lower-end is quite important, or else it just ends up sounding like trance, which I am not fan of (see: horrible). Once again, the 65th holds it's own. But when it comes down to listening to some Metal, I feel there is a slight over-emphasis on bass and lower-mids. Songs in which the lead guitar would shine using the K701, are now overshadowed by the rest of the band. Guitar solos especially I feel have lost their focus, and don't have the sense of power they would have If I used my K701. The low-end seems to overpower in songs in which the main focus is in the upper range.
However, I feel that the 65th fare better with acoustical recordings, in which the added lower-end helps make it sound less shiny then the K701. The K701 tended to make acoustic feel kind of fake, or overly-bright.
So there is a little give and take I feel, and with that, I think I'll keep my K701's, because with my personal tastes, it makes a great compliment to the 65th.
