Hmmm... i just double checked their website. They've actually still got the original sill for sale at $8.50 and the new memory foam ones for $12.25 which come in pleather and velour.
I do like the originals a lot, but it makes me wonder what the difference is. The original ones feel like clouds on my head!
Yup, I was going to sell my SHR440 the same day they arrived because stock pads were so stiff and hot on my ears. So happens I had some HM5 pads arrive that day and threw them on. Now SHR440 are one of my favourite headphones and incredibly comfortable when listening laying down. Your ears just sink into the cush cush goodness!
