So I picked up some of the brainwavz sheepskin round earpads for one of my fostex to try them one. They are pricey on amazon at $40 for a pair. Despite the price I like them on my purple heart fostex for now. While I was looking around though I ran across a cheapie pair of something similar by the maker Ablet. https://www.amazon.com/Ablet-Replacement-headphones-Sheepskin-Cushions/dp/B06XQY6LW3 Figured I would give them a shot on my 400i's since they were only $25. Got them in today and they are nice. Not the same as the brainwavz, but nice in their own way. They are memory foam, but a much denser/stiffer foam inside compared to the really squishy brainwavz. They only have them for the hifiman series so I wont be buying them for my other cans. I did also order another brand of sheepskin earpads as well I saw. https://www.amazon.com/NewFantasia-Replacement-Sennheiser-Headphones-Sheepskin/dp/B07B9M6GVV these NewFantasia for sennheiser cans. Figured I can try them out on by HD6XX and 598se cans I have. Love experimenting. I would love to try the Dekoni sheepskin pads on my other Fostex, I just have a hard time justifying their price tag though. More cans came in too! Well besides the Fostex THX00 Purplehearts I got from a fellow head-fier, I got set of the SIVGA SV003 but in the Rosewood from a good ebay deal. Someone had a pair with a make an offer. Offered $25 and got them! Paid more for the other pair, but these should also by nice too. I have a pair of the SIVGA SV002 with the dark color already. EDIT Doing an A/B comparison between the SV002 and the SV003. I can't hear any real difference between the two at all. So the only difference between the two is the SIVGA cutout on the side of the cups for the SV003 and nothing on the side for the SV002. There you guys go with that info for what it is worth. I like them both though for closed cans.
