I have very sensitive ears. To the point I will get sores if I have regular ear plugs in. I also have very good hearing (we call it supersonic). These actually fit well and did not hurt my ears by morning! The only downfall is they are only rated 29db. I can still hear my husband snore, but they quiet the sound down to the point where I can at least get to sleep and stay asleep. To give an idea of the volume blocker; I could not hear our ceiling fan and the window a/c was just a mild hum.
Bad quality ear plugs, these are not the original mack's ear plugs, I always get the ear plugs in the priginal packaging and they stay for a long time, and never fall out in the middle of the night like these cheap ones, I do not recommend these ear plugs.
holding it in hand first time gave me an impression of them being v squishy but boy, using it gave me feel of isolating from world's noise! loved it but i think it will wear out soon being too soft but happy for now with the product.
