We don't encourage someone to wear hearing aids that are not theirs for a  variety of reasons.   

For customers with access to audiology services, devices are customized to the individuals’ ear size (wire) and specific hearing loss needs. If the devices are worn by a different individual they may be getting too much onot enough gain, and will not experience the true benefit of the hearing aids

For customers who don't have access to audiology services and don't have the customization component, our Terms and Compliance* states that we can't transfer devices from one individual to another, so our Audiology Team is unable to provide services or support on devices.
