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.
