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.

Meta Ray-Ban Glasses (Gen 2)
The Meta Ray-Ban Glasses (Gen 2) is a budget-priced amplification product in the hearing glasses style, earning a B grade with a SoundScore of 3.8/5 in our lab testing. Priced at $375, this device ranks #2 of 8 in the Amplification Product category. In our testing, this product demonstrated exceptional strengths in music streaming quality, scoring 4.3/5—a remarkable 3.14 points above the category average. Own-voice comfort was equally impressive at 4.7/5, exceeding the category average by over 2 points. These results suggest Meta has prioritized the audio experience that their glasses are known for, delivering strong fidelity for streamed content and minimal occlusion-related discomfort. However, speech performance presents a more mixed picture. Speech in quiet scored 2.7/5, which is above the category average by 0.62 points but only mixed in absolute terms. Speech in noise measured 1.6/5—still above average for the category, but low overall. The most notable weakness is feedback handling at 1.9/5, falling 2.38 points below the category average. The Meta Ray-Ban Glasses (Gen 2) are best suited for users who prioritize music streaming quality and comfort over maximum speech clarity. Those seeking amplification primarily for challenging listening environments may want to consider alternatives with stronger speech-in-noise performance.
