I recently lost sound in one side of my IE8s. I found out the screen was clogged so I polled them both out and cleaned them with hydrogen peroxide. When I put them back in, the earphones lost most of the sparkle and became noticeable brighter. I am not a fan of bright headphones. Does anyone know how to fix this? And does anyone know why this would happen. Do the screens also double as filters? Thanks for your help!
