In stock configuration, mean stock pads and cable, Anniversary impressed me with electronica / trance music only. Classical and Jazz were not my liking, their midbass umph I was afraid of is there, but also the whole signature have kind of coating, which makes them sound like many already described, more forgiving, warmer and upfront.
Another story guys when you put normal pads on Anniversary model, they just become normal K702, so, basically and based on my first session, I conclude that pads make them sound like this. I did put Anniversary pads on normal K702 and here we go, Anniversary were back. To make the final call, I need more time. What I mean, is, if they sound fully identical when you switch pads, but right now, I would say, try Anniversary pads on your K702 and you will get very close sound to the original Anniversarys. Less exciting news is, the Anniversary pads seem to be not cheap and this may be the reason why, cos guys at AKG/Harman knew this will show up sooner or later, so, if you want Anniversary sound with your normal K702, you must pay the bill.
Thank you for this nice comparision.
