EarJellies Earplugs and Shape-Memory

EarJellies Earplugs have a permanent bulb-on-base shape, but that doesn't mean they are always that shape. When you roll out an EarJellies, you are teaching it a new cylinder-on-base shape that it will remember temporarily.

When you slide that cylinder into your ear canal and let it relax, the EarJellies will gradually forget the new shape and try to return to its bulb-on-base one. That shape-recovery takes a while and it's amazingly gentle. When the expanding EarJellies bulb reaches your skin, it exerts only the mildest of pressures and stops expanding. It seals perfectly, keeping noise and water out of your inner ear.
