I own the k702's but I can't use them. I bought them because my Rogue Cronus Magnum has a headphone jack but unfortunately it bleeds through my speakers so I'm hearing from inside and outside of the cans. Also the Rogue just doesn't have the guts for the AKG 's. They need power. That plus the fact that the sound bleeds through enough to wake my wife in our first floor master bedroom is a deal breaker for me.
I will say this about the AKG. My son brought over his Darkvoice headphone amp awhile back so I could have a proper listen. I played some Joshua Redman through the AKG 's and I could not believe how amazing it sounded. My son and I both agreed that Jazz sounded better through the AKG 's. We also thought that his heavy metal sounded better through his 650's. I think it depends on not only what you listen to but also your amp. If you like Jazz the AKG's win. Rock and metal go to
Sennheiser. Not sure about classical but I think you could go either way.
