Rechargeable: Unlike the AIR, the VOLT MAX is a rechargeable hearing aid that takes only 90 minutes to charge. Therefore, you will not need to purchase batteries.
Unlike the VOLT, the VOLT MAX comes with a portable charging/carrying case that allows you to charge your hearing aids on the go. Even if you don’t have an electrical outlet, the VOLT MAX carrying case holds its own charge. This means you can charge your hearing aids up to three times before you need to find an electrical outlet.
Personalization: Unlike the AIR or VOLT, the VOLT MAX is compatible with the MDHearing app, allowing you to personalize the hearing aid for your specific hearing needs and control the settings with a mobile device.
Better Noise and Feedback Reduction: The VOLT MAX has an adaptive microphone that will find the background noise and change the polar plot as needed to hear better in background noise. It also has a more advanced system for feedback reduction, noise reduction, and wind noise suppression than either the AIR or the VOLT.
