Review on KORE AVIATION Washable Cloth Ear Cover for Aviation, Racing, Gaming, Safety Style Headsets (Sold in Sets of 2) by Randy Bin

Bought these cases for a pair of gaming headsets. The improvement was immediate; my ears were no longer heated. That's why I bought them. I've just bought a new headset, and while it's comfortable, there have been times when my ears got hot (my previous headset had some sort of cloth cover, so it was much more comfortable). So they somehow make the headset more breathable. A side effect of this is that I hear a bit more ambient noise, so bear that in mind if that's important to you (my headset doesn't have active noise cancellation; active noise cancellation is probably still working as intended). Lid only and no built-in extra padding. So if you're reviving old headphones, pay attention. But in any case, they were perfect for what I needed them for.
