Uses Official HearAdvisor Lab Data
Audien Hearing Atom Hero
AudienSoundScore 3.3Grade B

Audien Hearing Atom

The Audien Hearing Atom is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.3/5 in our lab testing. At $89, it represents one of the most affordable entry points into amplification, though its performance reflects that positioning with a rank of #52 among 65 OTC hearing aids tested. The Atom's standout strength is its excellent feedback handling, scoring a perfect 5.0/5—above the category average by 0.46 points. This means users can expect stable amplification without the whistling that can plague some budget devices. However, speech performance is more limited: speech in quiet scores a mixed 2.6/5 (0.15 points below category average), while speech in noise drops to a low 1.0/5 (0.48 points below average). A significant limitation is the complete lack of music streaming capability, scoring 0.0/5—nearly 2 points below the already-modest category average. Own-voice comfort also falls below average at 2.1/5. These results suggest the Atom is designed purely for basic amplification rather than multimedia use. The Atom may suit buyers seeking the most affordable path to mild amplification who prioritize stability over advanced features. However, several competitors in the same price range offer substantially better performance—some scoring a full point higher. Those willing to consider alternatives may find meaningfully better speech clarity and additional capabilities without significant price increases.

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.
