The K701 seems to be a very recent batch with serial No. 728xx..... Im not sure if its the case, just a theory, could they have made changes to the K701 throughout the production runs to make it sound like the Q701 today that we couldnt see easily? Seeing how they also changed the headband from 7 to 8 bumps over time..
Hahah, maybe AKG was sneaky and silently updated the drivers of ALL K701, K702 headphones manufactured in the last 6 months to match those of the Q701.
So maybe the older K702s an K701 sound different than newer versions. Highly unlikely since I bought a K702 in summer of 2011. Could have just been older stock.
I don't think any of this is possible, but you never know..
It's not that I don't believe it when people say they both sound the same for THEM. It's just that the difference isn't even subtle. No golden ears required. Something really funny going on here..
Maybe someone can contact AKG. It's probably something so simple.
I think Zombie_X said he had a Guitar Center flyer once where AKG mentioned the improvements of the Q701. Something like it had smoother treble etc. Don't remember the exact wording.
