I unfortunately did not receive #69 either!  I was #6 on the drop and received #277.  I'm just glad they don't sound like my K701.

try the K701 pads on the K7xx. switching back and forth i prefer the sonics of the K701 pads over the memory foam. the memory foam is a little too bassy, warm and smoothed over. with the K701 pads, it sounds like a fleshed out K701 with more bass and reduced treble penetration.

i can't complain. i love this HP with the K701 pads. pure goldilocks.

By the way, my new Q701s distortion have magically disappeared. Damn burn in
Anyway, I think these new Qs may actually be identical to the K7xx except for the pads because first of all, they sound NOTHING like my old K701s and are pretty much my ideal sound. On a side by side comparison with HD600s out of the Vali, these have a similar amount of bass as the senns but with better control. The highs however are much nicer. Smooth yet extended and the soundstage is better than the hd600 as well. The senns sound congested, grainy, and dare I say it shouty in comparison similar to what I have read from purrin's comparison against the senns. All this plus ultrabike's Q701 measurements are leading me to think that these may just be the same cans as the k7xxx except for the pads. I wish someone that receives theirs can do a comparison with a later version chinese Q701.

Sorry, my Q701s are the earlier Made in Austria version. But people think to think the AKG 701 65 Annie/AKG K7xx are the same as Q701 but for pads. I have not tried switching to test this out but I would not be surprised if that is the case.

No. 65 here. No issues with rattling. Did a YouTube video of some bass sounds a little above listening level.  Have to put it through its paces more later. Did notice some upper mids prevalence.

My No.98 also no rattling.
The build quality is worse than my long gone MIA K701 though.
