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.  HearFIT Specifications & What’s in the Box SHOP NOW More Product Most Frequently Asked Question?
