These made my headphones feel like a brand new headset, after a couple of months of having used the new cups, I decided to drop a review for anyone being indecisive about buying them:
They are admittedly a little tricky to get on, nothing the video guide from Brainwavz didn't help me overcome - impressive given how dumb I am at times. Once on, they were like my headphones were not just brand new, but upgraded.
Compared to the factory ones, these are bigger, thicker, and more comfortable. They push the headset a little more away from my ears, and stop the little plastic nub (if you have the Arctis pro's, you know the bit I mean) off of my ears entirely. They are thick and very nicely padded, soft without being squishy at all. Comfortable for 12+ hrs a day, there's no heat build up like with the factory ones over long durations, and the cooling gel really gives them a luxury feel.
The cloth isn't rough or abrasive at all, very soft and pleasant against the skin, over all I strongly recommend these, even if you do not need new ear cups; they improve on an already amazing headset dramatically. 10/10, fully worth the price, and Brainwavz was super on top of the shipping as well.
