How to mold the Decibullz Ear plugs?

The molding process is quite easy, allowing you to mold the foam to the unique shape of your ears. This way you’ll get custom and secured comfort, as well as high hearing protection.

  • Boil two mugs of water in the microwave for five minutes. Make sure these plugs are microwaved separately or they will stick to each other. Then they will be useless and you’ll have to throw them out.
  • Alternatively, use a kettle of hot water and pour into two cups, place each ear plug in a separate cup.
  • Scoop them out of the mugs with a metal spoon. Don’t use plastic or the plugs will adhere to the spoon.
  • Let them cool for 30 seconds on a soft cloth. Not a paper towel. They’ll stick to the paper towel and you’ll have a mess.

When they’re cool to touch, soft and pliable, you’ll be able to work with them.

  • Put the earplugs into your ear, pushing with the pad of your index finger, working it down in until you feel as though it’s a good, snug fit. Make sure it’s not protruding out of your ear anywhere. Leave it in for 5 minutes.
  • Repeat the process with the other ear.
  • If not, the way they should feel or not blocking sound, remold and try again. They should fit tight, be comfortable not painful, and you should experience noise reduction.

Precautions for Decibullz Earplugs

There are precautions that come with all products. Decibullz earplugs have a list that comes with them. Of course, there are small parts with these plugs, so you want to keep them out of the hands of small children. They are a choking hazard.

Check that the silicone and foam canal tips are securely attached to the custom ear piece before every use. Remove the earplugs slowly and gradually -break the seal. Rapid removal may damage the ear drum.

Use only as directed. Failure to do so, the ear canal tip could become lodged in your ear which would require an Ear/Nose/Throat doctor to remove it. That would be the only safe removal strategy.

You want to wait until it is warm and pliable and soft before you insert it in your ear. An improper fit or doing it wrong will reduce the effects of the plugs and could even result in hearing loss or other injuries.

This custom earplug process actually seems pretty easy to do. Being molded in such a nice, tight, suction-cup kind of fashion, they seem as though they would have to block a lot of noise and, being custom, shouldn’t move around in the ear or try to fall out with any kind of motion.
