Hearing aid being cleaned

Cold weather can take a toll on your hearing aids. Here are some common problems and what you can do to protect your devices from damage.

Ear Wax Build-Up

During the winter months, earwax production increases to protect your ears from the lower temperatures. But excess earwax can harden and clog earmolds and receivers. To remove the build-up, wipe your devices with a dry cloth each night.


Despite their technological advances, hearing aids are still susceptible to moisture damage. The changes in ambient and body temperatures create condensation on hearing devices. Droplets can accumulate on mics, receivers and inside tubing and cause malfunctions.

Wear a hat, earmuffs or a sweatband to protect your hearing aids from condensation and perspiration. Take out your hearing aids each night to ensure they dry completely. You can also use dehumidifiers and drying kits to remove moisture from your devices.

Battery Charge

Colder temperatures drain batteries quickly, especially if you spend lots of time outside. Whether you’re taking a walk, traveling, or working, pack an extra set in case your batteries die sooner than expected.

After you come indoors, the battery compartment will collect moisture and will need to be wiped clean. Doing so will protect battery contacts and wires from corrosion.
