However, while the wires themselves may be somewhat waterproof, the cochlear implant as a whole is not completely waterproof. In particular, the external parts of the cochlear implant, such as the sound processor and microphone, need to be protected from direct contact with water or high humidity to prevent damage.
Therefore, when using a cochlear implant, you should avoid immersing it in water or exposing it to humid environments to protect the proper functioning and longevity of the device. In the event of inadvertent water damage or moisture in the leads, the device should be removed immediately and contacted as soon as possible for repair or replacement by the relevant healthcare provider or cochlear implant supplier.
