Your hearing healthcare professional can offer the best size and fit options for custom ear molds or other fixed options to help secure your hearing aids comfortably. They also assist you in connecting the hearing aids to smartphone applications and recommend other helpful devices, such as assistive listening devices. You can adjust the settings yourself using software programs or smartphone applications. ELEHEAR has developed an app specifically for its products to better meet user needs. If you still have hearing problems after using the device's built-in settings, you can seek help from an ELEHEAR online audiologist to install over-the-counter hearing aids.
