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

Audien Atom X

The Audien Atom X is a budget OTC hearing aid priced at $389 that earns a B grade with a SoundScore of 3.3/5 in our lab testing. This visible-in-ear style device ranks #54 of 65 OTC hearing aids tested, placing it in the bottom portion of its category. In our testing, the Atom X shows a mixed performance profile with notable strengths and weaknesses. Music streaming quality is a standout, scoring 3.3/5—a solid result that sits 1.38 points above the category average. Feedback handling is excellent at 5.0/5, meaning users can expect stable performance without whistling issues. However, the core speech intelligibility metrics are where this device falls short: speech in quiet scores just 1.5/5 (1.25 points below the OTC average), and speech in noise scores 1.0/5 (0.48 points below average). Own-voice comfort is mixed at 2.3/5, slightly below the category norm. At this price point, several alternatives offer stronger overall performance. Devices like the Elehear Beyond (4.34/5) and Apple AirPods Pro 2 (4.04/5) score meaningfully higher in the same price range. For those prioritizing value, the JLab Hear OTC delivers a similar SoundScore of 3.54/5 at a lower price. The Atom X may appeal to users who prioritize music streaming quality and want simple rechargeable convenience, but those seeking improved speech clarity—especially in challenging listening environments—should consider higher-performing alternatives in this competitive OTC category.

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.
