What a great invention. My husband has to wear his mask for 12 hr shifts, so you can imagine his ears get sore. I rigged him up an extension with a paper clip, it worked somewhat but he said it was a real pain. I got him these and he loves them. So easy to put on and off and you get 4 colors in the event you want so variety or want to match with your mask. These are soft, pliable yet seem very durable and should last quite a long time.
