Fit Analysis
Zepp Clarity One Performance by Fit Condition
We tested the Zepp Clarity One in both its Initial factory settings and after completing the Tuned adjustment process. The summaries below detail how each fit condition performed in our standardized measurements.
In its initial fit configuration with an open dome, the Zepp Clarity One achieved a normalized score of 3.6/5. Speech in quiet performed solidly at 3.3/5, while own-voice comfort was strong at 4.1/5—likely contributing to a natural listening experience out of the box. Feedback handling scored 4.2/5, indicating good stability. Speech in noise was limited at 1.1/5, and music streaming was not functional, scoring 0.0/5. The open coupling provides a natural sound quality but limits amplification for more challenging listening situations.
What is HearAdvisor's Initial Fit?
The Initial Fit approximates the most likely settings and eartips for a typical moderate hearing loss. Results are measured across the same 72 acoustic scenes in our custom-built lab, then scored on a 5-star scale using an auditory model.
