MDHearing VoltMax vs Starkey Genesis AI
Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

MDHearing VoltMax
The MDHearing VoltMax is a behind-the-ear OTC hearing aid priced at $699, earning a B grade with a SoundScore of 3.0/5 in our lab testing. This places it in the lower tier of the OTC hearing aid category, ranking 62nd out of 65 devices tested. In our testing, the VoltMax delivered mixed results across key performance areas. Its standout strength is excellent feedback handling, scoring a perfect 5.0/5—above the category average by 0.46 points. This means users can expect stable performance without whistling or squealing during typical daily activities. However, speech clarity proved challenging, with speech-in-quiet scoring 1.9/5 (0.93 points below category average) and speech-in-noise at 1.0/5 (0.48 points below average). Own-voice comfort measured 2.4/5, slightly below the category norm. A significant limitation is music streaming, which scored 0.0/5—nearly 2 points below the category average. Users who prioritize phone streaming for calls or media should consider alternatives. The device features rechargeable batteries, offering convenience over disposable options. At this price point, several competitors deliver substantially stronger overall performance. The VoltMax may appeal to budget-conscious consumers who primarily need basic amplification with reliable feedback control and don't require streaming capabilities. Those seeking better speech clarity or music streaming should explore higher-scoring options in this price range.

Starkey Genesis AI
The Starkey Genesis AI is a premium behind-the-ear prescription hearing aid released in 2023, priced at $4,798. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.7/5, ranking #33 of 39 prescription hearing aids tested. In our testing, the Genesis AI demonstrated excellent feedback handling, scoring a perfect 5.0/5—0.28 points above the category average. This makes it exceptionally stable during movement and physical activities. Speech in quiet performance is solid at 3.5/5, sitting 0.05 points above the category average. Speech in noise scores 2.3/5, which is 0.21 points above the category average but remains mixed in absolute terms. Own-voice comfort is a weaker area, scoring 2.2/5—0.50 points below the category average. Users sensitive to the sound of their own voice may notice this limitation. Music streaming quality is mixed at 2.8/5, essentially matching the category average with a +0.04 point difference. The Genesis AI shows meaningful improvement with professional tuning, with the normalized score rising from 3.5/5 at initial fit to 4.2/5 when tuned—a 0.8-point gain. The device offers rechargeable batteries and streaming compatibility with both iPhone and Android, plus hands-free functionality. However, at this premium price point, several competitors in the same range deliver notably higher sound performance scores, which prospective buyers should consider when evaluating options.
