If you are an earplug wearer, I can really recommend these. I have been using them exclusively for about 16 years now.
I have trouble sleeping, and light and noise at night really bothers me.
I started wearing earplugs in about 1988 when I worked at a hotel and lived above the nightclub. Those earplugs came from the local military base shooting range and were the standard yellow foam ones.
After that I moved and I had a neighbour who loved to entertain in his garden, which was right below my bedroom window. I switched to wax earplugs, which I found worked better because they moulded to my ear.
When I moved to Sweden I could not find wax earplugs and I could never go back to the foam ones, so I switched to silicone. I found Macks and have never looked back.
I can wear a pair for about three nights before I have to replace them, they are comfortable, fit really well (I must have strangely shaped ear canals because earbuds and in-ear earphones always fall out) and can be used for swimming as well.
You can buy them in pairs of 4, 6, and sometimes 8 (buy 6 get 2 free). I buy the 6 packs in bulk on Amazon – usually about 8 boxes at a time.
and…..the little boxes from the 2 pack are perfect for keeping cotton buds in your makeup bag when you have finished the earplugs. These little boxes never ever break. I have been using this box for years!
