Audien Atom X vs Zepp Clarity One
Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

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.

Zepp Clarity One
The Zepp Clarity One is a mid-priced OTC hearing aid with an invisible-in-ear design, priced at $699. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.9/5, ranking #23 among 65 OTC hearing aids tested—placing it in the top 34% of the category. This device demonstrates notable strengths in speech clarity during quiet environments, scoring 3.7/5—nearly a full point above the category average. Own-voice comfort is another highlight at 3.8/5, measuring 1.29 points above average, which suggests reduced occlusion effects that many users find bothersome with in-ear devices. Feedback handling is excellent at 5.0/5 in the tuned configuration. However, the Clarity One has significant limitations. Speech understanding in noisy environments scores just 1.4/5, slightly below the category average. Most notably, music streaming scored 0.0/5—nearly 2 points below the category average—indicating this device does not support audio streaming functionality, a feature some competitors in this price range offer. The Zepp Clarity One is best suited for users who prioritize clear speech in quieter settings and natural own-voice quality, and who do not need music or media streaming capabilities. Those seeking better noise performance or streaming features should consider alternatives, including options like the Olive Union Air, which offers similar overall sound quality at a lower price point.
