Frequently Asked Questions

  • Is IRIS20 a hearing aid?
    • Since IRIS20 didn’t go through a process of certification for medical devices, it cannot be sold as a hearing aid. It is classified as a personal sound amplifier instead.
      However, its performance is identical to those of hearing aids because IC chips and software algorithms specifically designed for hearing aids are used to make our devices.

  • For which level(s) of hearing loss can IRIS20 be used?
    • It is suitable for people with mild ~ moderately severe hearing loss.

  • How do I know which level of hearing loss I have?
