AudienSoundScore 3.3Grade B

Audien Atom Pro 2

The Audien Atom Pro 2 is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.3/5 in our lab testing. Available for $289, this visible-in-ear device delivers solid performance in some areas while showing limitations in others. In our testing, the Atom Pro 2 demonstrated excellent feedback handling, scoring a perfect 5.0/5—0.46 points above the OTC category average. This means users can expect stable performance without whistling during typical daily activities. Own-voice comfort scored 2.6/5, slightly above the category average, suggesting acceptable naturalness when speaking. However, speech clarity presents a mixed picture. Speech in quiet scored 2.3/5 (0.49 points below category average), and speech in noise scored a low 1.3/5 (0.16 points below average). The most significant limitation is music streaming, which scored 0.0/5—nearly 2 points below the category average—indicating this device is not suitable for those who want to stream audio from their phone. At this price point, several alternatives offer stronger overall performance, including the Elehear Beyond and Apple AirPods Pro 2. The Atom Pro 2 may suit budget-conscious consumers who prioritize feedback-free operation over streaming capabilities and don't need maximum speech clarity. Those seeking better speech performance or any music streaming should consider higher-scoring options in this price range.

MDHearing VoltMax Hero
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.
