I know cotton swabs aren?t meant to be used for the ears but that?s the primary use for them in my household. I love the idea of these slippers however, not easily to walk in because of the extra weight of the rice or whatever they use to heat up. My daughter is a concrete driver/laborer. My old headphones broke. Were very well made, but for my space available they didnt fit. Update 09/10/2020:Well, hand washing numerous times has caused the adhesive that bonds the sole to the fabric to become contaminated and odors cannot be removed. Labels are high quality and generous in number. Even the case was just slapped in at the top lose! I usually wear a size L in shirts but decided to get this product in a medium since I know things tend to stretch after a few wears or get looser with weight loss, it fit perfectly in my opinion. Installed with out a hitch.
