RayFSo many uses...
One of us at the office put some in his bike helmet to replace the foam that wore away, and he says it helps the air flow better over his head and keeps him cooler. We told him he was cool already, but whatever ¯\_(ツ)_/¯
The wife of one of our staff can’t wear most headphones; she has a great mind, but a small head! Many headphones don’t adjust short enough for her, so she usually used earbuds and earclip headphones, but now she can finally wear an Audeze LCD2C without the pads sliding down off her ears. We’ve gained a new unofficial pad tester!
