  3. How do I look after my hearing aids?
    Hearing aids are small and fragile. Handling them with care is very important for a longer lifespan. Here are few tips to help you take care of them.
  • Store your hearing aid in a safe place that is dry and cool.
  • Change hearing aid batteries often so they don’t suddenly run out of power.
  • Switch off your hearing aid when you’re not using it. If you don’t use it for a long period of time, remove the battery.
  • Battery contacts should be cleaned regularly. Use a cotton swab, taking care not to bend the contacts. Dirty battery contacts can cause improper device function.
  • Accumulated earwax may prevent sounds from traveling from the hearing aid into the middle ear. Contact your doctor regularly to have your ear canals cleaned. Never remove the earwax from the ear yourself. Doing so could damage your ear.
  • Remove earwax from your hearing aid to prevent temporary malfunction or permanent damage by cleaning your hearing aid (see below).
  • Clean your hearing aid using the small brush or the soft cloth that came with it. Never insert tools into the sound outlet. Doing so could damage the receiver. If you can’t clean the hearing aid completely, please call us and we will assist you. ask your hearing professional for help.
  • Don’t wear your hearing aid in the shower, when swimming or when using a hair dryer, hair spray or other types of spray.
  • Do you have tips for me to better increase the lifespan of my hearing aids and its batteries?
    • When starting a new pack of batteries, you should not remove the plastic tabs on the back of each battery until you are ready to use them. Hearing aid batteries are powered by zinc air, meaning they are activated by air. When the tab is removed you are essentially starting the battery.
    • Store hearing aid batteries at normal room temperature. It is also good practice to store hearing aid batteries away from coins, keys and other metal objects because this may cause the batteries to short circuit.
    • When the time comes to replace the battery in your hearing aid, you should wash your hands thoroughly. Grease and dirt on hearing aid batteries can cause damage to the hearing device.
    • Once you remove the plastic tab on the back of the battery, you should let it sit out for 1 minute. This allows the hearing aid battery to take in enough air to power up before it is placed in the hearing aid.
    • Anytime the hearing aid is not being used, it should be turned off by opening the battery door (leaving the battery inside), placed in a safe spot. This minimizes battery drain and allows moisture to escape, which will keep the battery from corroding and damaging your hearing aid. If you don’t plan to wear the hearing aid for an extended period of time, it is a good idea to remove the battery entirely.
  • Who are the manufacturers of your hearing aids?
    nessa currently sources our hearing aids from a world-class manufacturer of medical devices, ReSound, renowned for their high quality hearing aids.More information on our hearing aid manufacturers: click here.
