Are you looking for ear plugs that don't fall out? Many people find that they have problems with many types of earplugs not staying in. The foam variety are probably the worst for this, particularly whilst asleep. This is because they expand in the ear and push out during the night. This lead to you being woken up when they fall out. The ear canal tapers towards the outside, meaning that as the plug expands its emerges from the ear.
Moulded earplugs are ideal if you have problems with this. Because they do not expand in the ear canal they do not push themselves out. As they are shaped to the contours of your ears they fit like a hand in a glove, locking into place. This means that if you turn over in bed they stay in place.
This also makes them great for swimming, surfing and any time you are moving around whilst wearing your earplugs.
