If you chose foam, roll the ear tip between your fingers before inserting them. This will warm the ear tip, making it easier to insert. Silicone ear tips can be inserted as they are.
Insert Loop by taking the earplug between your thumb and index finger. To ease insertion, pull the top of your ear. Gently push and twist until the ear tip seals your ear canal completely.
Remove Loop with a slow twisting motion to gradually break the seal.
