These have to be the most comfortable ear pad replacements I've used! I have them on my ATH-700Xs and my DT770 Pros and they've made a pretty large comfort difference on both of them as well as adding noise isolation. I have huge ears and needed more distance and inner opening diameter and they fixed my issues on both headsets. Would recommend for my fellow big ears! Even if you have small ears, you're still getting way more comfort over the original pads. They were also easy and painless to install. Plenty of material to get over the lip where the original pads were.
