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.

Nuheara IQBuds Max
The Nuheara IQBuds Max is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.3/5 in our lab testing. Priced at $499, this visible-in-ear device from 2021 ranks #46 of 65 OTC hearing aids tested, placing it in the top 69% of its category. The standout feature of the IQBuds Max is its exceptional music streaming performance, scoring 4.3/5—a strong result that sits 2.38 points above the category average. For users who prioritize audio entertainment alongside hearing assistance, this device delivers notably better streaming fidelity than most OTC alternatives. However, speech performance presents a mixed picture. Speech in quiet scores 2.0/5, falling 0.78 points below the category average. Speech in noise is essentially at par with competitors at 1.5/5, which is above average for the category but low in absolute terms. Own voice comfort also trails the category average by 0.31 points with a score of 2.2/5. Feedback handling scores a solid 3.4/5 in absolute terms, though this falls 1.14 points below the category average. The IQBuds Max is best suited for users who value music and audio streaming quality over speech clarity, particularly those seeking an affordable entry point into amplification. Competing devices in this price range—including the Elehear Beyond (4.34/5) and Apple AirPods Pro 2 (4.04/5)—offer stronger overall sound performance for similar investment.
