You control Vivia using onboard buttons, tap controls (microRIE only), or the ReSound Smart 3D app. Beyond basic remote functions for program and volume adjustments, the Smart 3D app lets you change the directional response of the hearing aid (e.g., FrontFocus), adjust tones (bass and treble), monitor battery life, and more. A "Find My Hearing Aids" feature helps you locate your hearing aids if they're misplaced, and there are tinnitus management options with customizable tones. The app also allows users to request remote care from their hearing provider for convenient adjustments and firmware updates.

Although M&RIE is useful, it has been found in the field to be best for those with specific hearing losses (for details, consult with your hearing provider).
Beyond this, Vivia offers the same advanced LE Audio and Auracast capabilities as the previous-generation Nexia hearing aids. Continue reading for details.
