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 Edge AI RIC
The Starkey Edge AI RIC is a premium prescription hearing aid released in 2024, priced at $5,000 and earning an A grade with a SoundScore of 4.3/5 in our lab testing. This behind-the-ear device ranks #20 of 39 prescription hearing aids tested, placing it in the top 49% of its category. In our testing, the Edge AI RIC demonstrates notable strengths in speech clarity and music streaming. Speech in quiet scores a strong 4.1/5, measuring +0.68 points above the category average. Music streaming stands out at 3.8/5, a solid score that sits +1.04 points above what we typically see in prescription devices—making it a compelling choice for users who value phone audio quality. Speech in noise scores 2.6/5, which is above the category average by +0.54 points but remains mixed in absolute terms. Feedback handling is excellent at 4.7/5, though this sits just below the category average of 4.72/5. Own-voice comfort scores 2.8/5, slightly above average but mixed overall—something to consider if own-voice naturalness is a priority. The device showed meaningful improvement from tuning: the normalized Initial Score of 4.2/5 rose to 4.7/5 after professional fitting, a +0.5 point gain. As a 2024 Expert's Choice Award winner, the Edge AI RIC offers strong everyday speech performance and standout streaming capabilities. However, buyers in this premium price tier should note that several competitors—including the Phonak Sphere Infinio and Oticon Intent—achieve higher overall scores. The Edge AI RIC is best suited for users who prioritize music streaming quality and strong speech clarity in quieter environments.
