"...the price of one earpad for the K701 ($35) and for the K702 ($40). So one pair of earpads costs $70 for the K701 and $80 for the K702.
I can't believe this. Are these the most expensive earpads ever?"
Anyone know how much Ultrasone Ed.8 ear pads are? 
On a more serious note, whatever the Ed8's cost is, it comes from stitching that leather - marketing fluff or not just think of it as how much it would cost if you nicked the seat on a Jaguar vs a Honda. For the K701/2, it may be because of the shape - it's thicker on one side than the other. AKG relies on the pads to angle the drivers, unlike the T1 and HD800 for example that angles them on the mount/chassis. You can argue that might be wrong considering the pads compress and change shape over time, but when you consider the effect of economies of scale - specifically paying $90 for those obscure strips of foam on the HD800 - paying $70 every 18 months or so to maintain your K701's sound may not be that expensive after all. (But then again, for all I know the HD800 pads last longer)
