Dr. Smithsons Mask Extender Straps for Back of Head (5-Pack) - Non-Slip & Adjustable Mask Straps for Back of Head | Ear Savers for Masks Strap Tightener Fastener Expander for Adults, Kids

The extenders made it possible to remove the mask without pulling out the over-the-ear hearing aids.

These are great and I use them at mass as well as other places but there is a caveat: Before you use them, take them apart and reassemble to ensure the straps are firmly held in place.The first several times I used them, the straps "flew" out of the clip and the parts went flying (see the photo). This was at mass and was somewhat disturbing. I had another one as a spare and the same thing happened. I was going to return them to Amazon and then realized all you have to do is to unscrew the strap holder and make sure the strap is placed properly then re-assemble tight. After that, it's all good. I was going to use glue but so far the re-assembly works well.Again, these are great but you have to prepare each one before use.

I didn't want to lose a cloth mask that a friend made for me, nor do I want to litter if I use a disposable one. So this is like a leash for it, and the plastic hook won't clang or rust as a metal one would. (It doesn't swivel, but it doesn't need to.) It keeps my mask handy when I don't have to wear it (when no one's around), and fast/easy to put the mask on/take off with only touching the ear loops or this cord. It can also be used for double-masking, as long as each mask is earloop style. Works even with beanies on. Stays put and doesn't slip. My ears love it.

Really good, but the clip that holds the two chords together sometimes pops off and needs to be resecured. I use them to keep my mask on at CrossFit. And I’ve never had a problem.

Never loose my mask! Fits well
