Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

JLab Hear OTC
The JLab Hear OTC is a budget-priced OTC hearing aid released in 2024, earning a B grade with a SoundScore of 3.5/5 in our lab testing. At $100, it represents one of the most affordable entry points into the OTC hearing aid market, ranking #36 of 65 devices in its category. This visible-in-ear device delivers a distinctive performance profile with clear strengths and weaknesses. Its standout feature is excellent music streaming quality, scoring 4.6/5—a remarkable 2.68 points above the category average. Feedback handling is equally impressive at 5.0/5, meaning users can expect stable performance without whistling during daily activities. These results suggest JLab leveraged its audio expertise from consumer earbuds in developing this product. However, speech clarity presents challenges. Speech in quiet scored 2.1/5 (0.67 points below category average), while speech in noise scored 1.0/5 (0.46 points below average). Own-voice comfort also measured low at 1.8/5. These limitations are significant for users prioritizing conversation clarity, which is typically the primary reason people seek hearing aids. The JLab Hear OTC is best suited for budget-conscious consumers who value music and media streaming alongside basic amplification, rather than those needing maximum speech intelligibility. Features include rechargeable batteries, iPhone and Android streaming, and hands-free functionality. Buyers seeking stronger speech performance in this price range may want to compare options like the higher-scoring Elehear Beyond or Apple AirPods Pro 2.

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.
