Ok for the last couple of days I’ve been analyzing and comparing the angled spring foam K702 pads against non-angled memory foam anniversary pads in my K702 anniversaries. I’ll start my impressions by showing you a side by side photo of the pads.
From the photo you see that the anniversary pads are about as thick as the thinnest part of the K702 pad. The spring foam feels lighter against your skin and doesn’t compress practically at all, which means they don’t produce much heat or hot spots. With K702 pads you’re left with plenty of space between your ears and the drivers. Anniversary pads, on the other hand, compress a lot more, which means they also seal better and the drivers are located closer to your ear. Accordingly, you need less amplification in terms of loudness. The anniversary pads seem to collect a lot of dust, hair and other impurities, but they are quite easy to clean.
