Do not buy! I just got them in the mail yesterday and they're already in the trash. They arrived curled up and crashed into each other. It didn't bother me that much because I bought headphones that did. I would just wash them and air dry them to get them back to normal. They did, but unfortunately they also bled everywhere. Yellow, purple and orange markings are visible on the gray filter straight out of the box. I washed one and let it dry. Apart from the stains, everything looked normal. Then I did the same with purple. When I returned an hour later, I found a faint purple stain on my dressing table. Solid quartz! No, it won't. Luckily I'm exchanging it. If I had already done that, I would be so angry. Do not buy.
