You really think these have better low bass extension than the Q701 and K702? I mean if so is it more forward sounding? I found this really hard to believe if it's the same driver.
I imagine it just has more mid/upper bass and sacrifices the treble a little. There some recordings i've found lately with low bass that's inaudible on my HD-650 and Q701. It's so uncommon that it's not a big deal.
Hopefully the imaging is as good as the K601 and I think it will be.
I just have this feeling that if AKG released a 701/K702 headphone with completely flat bass down to 10hz it would ruin it's sound. You add something to one part of the signature and something else gets messed up. I never want to sacrifice my mids for more bass.
I'm a bit worried this might have too forward of low mids, but it's highly unlikely.
