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.

ZeppSoundScore 3.9Grade B

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.
