Most hearing aids are only meant to help compensate for hearing impairments. A hearing aid that is more complex or offers multiple functions can be costly and require a qualified individual to configure the device, and further provide additional maintenance.

The Petralex app provides total hearing aid functionality, giving the user the benefits of a high-end hearing aid, but for a fraction of the cost. It's comfortable enough to be used every day.
