Lab Assessment

How the Zepp Clarity One Performed in Independent Testing

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.

Test Documentation

Fit Observations and Test Configuration for the Zepp Clarity One

Our technicians documented observations during both Initial and Tuned fitting procedures for the Zepp Clarity One. The notes below detail the specific test configuration and any relevant fitting considerations observed during measurement sessions.

Lab Notes

Initial fit observations

With the initial open dome fitting, the Zepp Clarity One achieves a normalized score of 3.9/5. Speech in quiet performs well at 3.5/5, while own-voice comfort is strong at 4.1/5, suggesting good occlusion management out of the box. Speech in noise is limited at 1.6/5, and feedback handling scores 4.2/5. Music streaming is not supported, scoring 0.0/5. This configuration offers solid performance for everyday quiet conversations with minimal setup required.

Tuned fit observations

After professional tuning with a power dome with slits, the normalized score improves slightly to 4.0/5. Speech in quiet increases to 3.7/5, and feedback handling reaches an excellent 5.0/5. Own-voice comfort remains solid at 3.8/5, though slightly lower than the initial fit. Speech in noise drops marginally to 1.4/5. The more occluding coupling helped improve feedback stability and speech audibility, though the device still lacks music streaming capability.
