I recently purchased a pair of custom leather and memory-foam ear pads from Vesper Audio (https://vesperaudio.com/) to replace a worn-out pair of pads for my ATH-ESW990H headphones. The stock earpads are leather, but rather thin and a little painful, at least for me. They also have to be ordered from Japan through Ebay and cost ~50 USD. Vesper made me ear pads, customized to my requested dimensions, for just a few dollars more. They are excellent. They are much more comfortable. Look great. And fit the headphones perfectly. I'm very happy with them. There aren't many options for custom ear pads, so I wanted to share with people my positive experience with Vesper.
