With the WS55 pads they are almost over-ear for me since i have medium smallish ears and they are pretty comfortable. But i am sure the comfort level in outta this world with those es9 lambskin pads. haha But they are spendy though. Danny has them so he can chime in on those. The only negative beside the small on ear pads is the lumpy headband when worn. Don't get me wrong cuz they are soooo comfy but it just turns lumpy when it's worn. It doesn't look that bad, but just bring the sexiness level of these stainless steel cup beauties down a notch a bit.
So you might want to keep that in mind as well, not really a deal breaker but still...... i is shallow like that.
Thanks. Why do you like them more than the WS99's?
