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.
Headband bumps arent a problem for me, I just worry about possible midbass, because presense of more lower end, which can push the mids pretty nasty and I am not looking for that. Also, they have been compared to HD650 many times up here, which is no go for me.
But, if Anniversary edition have kept their balance, then we have a winner, I guess...
Keep in mind I don't have the K701 on hand to do a direct comparison, but I have owned them on a few separate occasions -- so take these impressions with a grain of salt:
I think AKG managed to boost the bass without intruding on the mids. To me, the K702.65 sounds very much like the K701 in the mids and treble. I think the bass boost in the K702.65 essentially comes "for free" -- meaning they didn't sacrifice any other part of the sound to get it. I don't think the bass / midbass intrudes into the mids at all.
I also don't think the K702.65 really improves much on the low-bass extension when compared to the K701. I think the bass extension and quality are about the same, but the K702.65 has more quantity.
Imaging sounds just about the same to me between the K702.65 and the K701. Which is to say that the imaging is quite sharp, and bested only by a couple other headphones I've heard (namely, the T1 and R10). If anything, the soundstage on the K702.65 may be just a bit smaller than the K701 -- probably due to the pads, as I think the drivers sit a bit closer to the ears.
Personally, I don't think these sound like an HD650. They sound much more like a K701 to me, just with some extra bass. I think that the differences in the K702.65 may have been overstated a bit. If you're looking for a K701 with a little extra bass, these are worth trying. If you didn't like the K701, it might be wise to steer clear of the Anniversary edition.
