Designed for easy maintenance

Hearing aid care has never been easier, thanks to EasyGuard domes, which protect your hearing aids from earwax and make maintenance simpler.7

EasyGuard™ features a sealed design that helps prevent earwax from entering the hearing aid receiver while allowing sound to pass through. This provides easier care and more consistent performance.
