Insert properly: gently twist/insert until it seats comfortably, then check that your helmet liner rests normally without dislodging the ear-plug. Test communications: switch on your intercom or radio and ensure you can hear incoming and outgoing clearly while ambient noise is reduced. Ride/test: go for a short ride; note how your ears feel after 30 minutes – less fatigue, less wind roar. After use: remove filters, wash ear-tips in warm water, dry thoroughly, store in carry-case. Regular cleaning improves lifespan. Check for wear: if you observe damage, reduced seal or discomfort, replace ear tips or filters. Helmet compatibility: Some helmet liners push closer to ear canal; make sure earplug fit doesn’t interfere with helmet liner or head fitting. For frequent use: Consider upgrading to the custom-fit version (Serenity Choice Plus) for enhanced comfort and fit.
