My K702 must be several years young, bought them used up here and the seller stated to used them for say 500 hours in 2 years, so, I guessing on year 2010-2011, serial number is 2052, the pads are angled and just as comfy as K701 I had on loan or Anniversaries. K701 were / are from earlier production, I believe, with 7 bumps on headband with angled pads as well. My Q701 were from end 2012 and they smell like cheap plastic with pads that gave me irritation. For example Anniversary I got, dont smell at all, so, does it mean they use differ plastic? If so, it may have influence as well, isnt?
I suspect that Q701 will sound pretty bass heavy with Anniversary pads, would surprise me if they dont. Today, I was listen to Paul van Dyk CD "In Between", using Anniversaries, man, to just point one thing, bass was so impressively tight and punchy, without any boom and they seem to be fast as well.
If the K702 with 65th pads sound identical to the 65th, I'd hate to hear what the Q701 sounds like with the 65th pads. Maybe it will be magically downgraded to an HD-650 (sorry,only kidding!).
How old is your K702? My K702 I had in early 2011 was quite a lot different than the Q701. Had them both at the same time. Perhaps your K702 is one with possible new drivers. Nobody has ever confirmed if they had a K702 that sounds 100% identical to the Q701 though. Was your K702 purchased in 2012 or 2013?
My guess is that to get the sound of my Q701 closer to the REAL 65th, i'd have to install K702 outer grills and remove the foam.
BTW did you know that the K601 gets bassier with no outer grill? This is totally opposite of my Q701 (based on memory).
I wonder how the 65th would change with the outer grill removed or the Q701 foam and button added.
It'd be funny if my Q701 with 65th pads was warmer and bassier than the stock 65th. Hardly possible..
