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.
Choice
Oticon Intent
The Oticon Intent is a premium behind-the-ear prescription hearing aid released in 2024, priced at $4,898 and earning an A grade with a SoundScore of 4.8/5 in our lab testing. This places it at #4 among 39 prescription hearing aids tested, within the top 8% of its category. In our testing, the Intent demonstrates notable strengths in speech performance, scoring 0.54 points above the category average for speech in quiet and a substantial 0.95 points above average for speech in noise. Music streaming is a particular highlight, measuring 1.24 points above the category average with a strong 4.0/5 score. Feedback handling is excellent at 5.0/5, slightly exceeding the already-high category average. The primary limitation revealed in our testing is own-voice comfort, which scores 1.3/5—a low absolute score that falls 1.40 points below the category average. Users sensitive to the sound of their own voice may find this characteristic noticeable. This is a common trade-off in devices optimized for speech audibility. The Oticon Intent is well-suited for users prioritizing speech understanding across varied listening environments and high-quality audio streaming. It has earned HearAdvisor's Expert's Choice Award in both 2023 and 2024. Shoppers in this premium price tier may also consider the Phonak Sphere Infinio (#2) or the lower-priced Oticon Zeal, which offers strong performance at a reduced cost.
