Using a cochlear implant with Kanso®

Answers to some common questions about living with a cochlear implant and Kanso® Sound Processor.

  • Do I have to limit my sports activity? What about scuba diving and swimming?

    Kanso sound processors have an IP54 rating, which means you can splash around in water and walk in the rain without worrying that it will affect your processor.

    If you want to go swimming, you should use an Aqua+ for Kanso. This flexible silicone sleeve fits over your Kanso and makes it completely waterproof.

    Your internal implant is validated to withstand pressure at a depth of 25 metres (82 feet) underwater. However, Cochlear's testing for the Aqua+ for Kanso did not exceed three metres, so it is not recommended to wear your Kanso at greater depths.

    For contact sports you should wear a helmet to protect your equipment. Boxing and other aggressive sports are discouraged.

  • Are MRI scans safe with a cochlear implant?

    Inside each cochlear implant is a magnet. To ensure MRI compatibility for cochlear implant recipients, the Cochlear™ Nucleus® Implant System contains a removable magnet. Cochlear was the first to introduce this key safety feature nearly two decades ago. The magnet is easy to remove and replace if needed. In the rare case that a recipient needs serial MRIs, a no-magnet option is available. The importance of this design feature is reinforced by radiologists.

    Cochlear Nucleus implants are also compatible with routine (1.5 T) MRI with magnet in place and 3.0 T with magnet removed, should your doctor specifically recommend this procedure (reference 1).

    1. Cochlear Nucleus implants are compatible with routine (1.5T) MRI with magnet in place by TUV and TGA. Not approved by the FDA.
  • What type of batteries does my Kanso need?

    For everyday use, the Kanso Sound Processor uses two high-power 675 (PR44) zinc air disposable batteries. Please note that you will need to use other battery types if using the Cochlear™ Nucleus® Aqua+ for Kanso accessory. Please see its user guide for details.

    Your local Cochlear team will be able to direct you on the best place to purchase these batteries.

  • Do I need to avoid magnetic toys or magnetic underlays?

    No. You can safely use these items as they have low magnetic strength.

  • How do I get the best out of my device when listening to music?

    No two people have the same experiences, and listening to music with a cochlear implant is no different. It takes a little dedication and practice to find your groove.

    Tips for listening and enjoying music

    • While listening to music, it helps to read along to the lyrics. Often you can find lyrics in the sleeve insert of a CD and you can find thousands of lyrics online. Some customers find that watching music videos online (e.g. YouTube) helps them to understand lyrics better.
    • Music may not sound good to you at first. Remember, patience, persistence, practice and a positive attitude will go far.
    • Experiment with different types of music.
    • Start by choosing simple songs or familiar tunes, such as children's songs.
    • Set aside time to practice in a quiet environment when you are not tired.
    • Work with your audiologist to optimize your MAP and/or create a music program.

    Consider using a Cochlear™ Wireless Phone Clip or Mini Microphone

    The Cochlear Wireless Phone Clip allows you to stream music from your smartphone direct to your Kanso via Bluetooth technology.
    The Cochlear Mini Microphone 2+ can also be used to stream music wirelessly to your Kanso. Simply attach the cable supplied with the Mini Microphone 2+ to the music device’s audio out socket and also your Mini Microphone 2+. You will then be able to stream the music to your Kanso. You can also plug the Mini Microphone 2+ into a computer or other devices that have a headphone jack or audio out socket.

  • How long do the batteries in the processors last?

    Batteries should be replaced as needed, just as you would with any other electronic device. Battery life varies according to the programs used each day, your implant type and the thickness of skin covering your implant. Your Kanso Sound Processor has been designed to provide most users with a battery life of more than 16 hours for typical use with zinc air batteries. However, this will vary depending on your system settings and hearing situations. To help you get the longest life from the batteries, your Kanso will turn off two minutes after you take it off your head.

  • Can I have an x-ray at the dentist?

    Yes, cochlear implant recipients can have x-rays at the dentist.
