MDSoundScore 3.0Grade B

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.

ReSound OMNIA RIE Hero
ResoundSoundScore 3.9Grade B

ReSound OMNIA RIE

The ReSound OMNIA RIE is a premium prescription behind-the-ear hearing aid released in 2022, currently available at $4,498. In HearAdvisor's lab testing, it earns a B grade with a SoundScore of 3.9/5, ranking #31 of 39 devices in the prescription hearing aid category. This device shows notable strengths in speech clarity for quiet environments, scoring 3.7/5—a solid result that sits 0.34 points above the category average. Own-voice comfort also performs above average at 3.0/5, which may appeal to users who find their own voice bothersome in other devices. Feedback handling is strong in absolute terms at 4.1/5, though it falls 0.62 points below the category average of 4.72/5. The OMNIA RIE's most significant limitation is speech in noise performance, scoring just 1.0/5—a low result that trails the category average by 1.11 points. For users who frequently encounter challenging listening environments like restaurants or group conversations, this represents a meaningful gap compared to alternatives. Music streaming scores a mixed 2.7/5, essentially matching the category average. The device offers flexible power options with both rechargeable and disposable batteries, plus streaming compatibility with iPhone and Android devices including hands-free functionality. However, at this premium price point, several competitors deliver stronger overall performance, including options from Phonak, Oticon, and Widex. The OMNIA RIE may suit users who prioritize quiet-environment clarity and own-voice comfort over noise-handling capabilities.
