If you are looking for the best ear plugs to block the sound of snoring then molded ear plugs
will be ideal. The are individually fitted so feel very comfortable and are made from materials which last for years. ZenPlugs are even antibacterial so help prevent ear infections
Foam ear plugs are not ideal because they expand. They push themselves out of your ears and cause pressure which can be uncomfortable. When they fall out you hear the noise of the snoring, waking you up. They protrude from the ears, like rubber flanged ear plugs tend to. This means they are uncomfortable for sleeping, making them unsuitable.
Wax and soft silicon varieties aren't ideal because they both trap hair and dirt, making them unhygienic with repeated use. This shortens their lifespan, making them expensive if used over a longer period of time due to the cost of repeated replacement.
Although molded ear plugs are more expensive to buy initially they end up being cheaper in the long run. This is because the cost-per-use is much lower due to the fact they last for several years with normal use. Choose a bright colour from ZenPlugs so you can find them easily if you drop them on the carpet or in your be.
