Sony CRE-C10
The Sony CRE-C10 is an invisible-in-ear OTC hearing aid priced at $798, earning an A grade with a SoundScore of 4.2/5 in our lab testing. This places it at #12 of 65 devices in the OTC category, putting it in the top 17% of tested OTC hearing aids. Speech performance is where this device truly shines. Speech in quiet scores an excellent 4.5/5, a full 1.71 points above the category average of 2.79/5. Speech in noise performance at 2.9/5 is mixed in absolute terms, though still 1.39 points above the category average of 1.48/5. These speech clarity strengths have contributed to the CRE-C10 earning Expert's Choice recognition in both 2023 and 2024. The device does have notable limitations. Music streaming scores 0.0/5, which is 1.92 points below the category average—this device is not designed for audio entertainment. Feedback handling scores a solid 3.5/5 in absolute terms, though this is 1.04 points below the category average of 4.54/5. Own-voice comfort is mixed at 2.6/5, essentially matching the category average. The Sony CRE-C10 is best suited for consumers who prioritize speech understanding over streaming capabilities and want a discreet, invisible-in-ear form factor. Those who frequently stream music or media should consider alternatives like the Sony CRE-E10, which scores higher overall in this price range.

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.
