These earmolds are highly recommended for sleeping.
Significant noise exposure can be very harmful. Custom earplugs can protect hearing in noisy situations, for example when working in a noisy environment or hunting.
Cleaning earmolds for sleep
Use the brush to remove earwax and other debris from all surfaces of the earmolds. Wipe your earmolds gently with VapoLobe or ServiLobe. Never use rubbing alcohol on your earmolds, as it can wear them down and make them less effective.
