Overall Assessment

Where the Zepp Clarity One Delivers and Where It Falls Short

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 its category.

This device demonstrates notable strengths in specific areas of sound performance. Speech clarity in quiet environments scores a solid 3.7/5, coming in 0.95 points above the category average. Own-voice comfort is another highlight at 3.8/5, exceeding the category average by 1.29 points—a meaningful advantage for users sensitive to how their own voice sounds while wearing hearing aids. Feedback handling is excellent at 5.0/5, among the best we've measured.

However, the Zepp Clarity One shows limitations in other areas. Speech understanding in noisy environments scores 1.4/5, slightly below the category average and low in absolute terms. Music streaming capability is notably absent, scoring 0.0/5—well below the already modest category average of 1.92/5. Users who prioritize phone audio streaming should consider this significant limitation.

The Zepp Clarity One may suit consumers who primarily need hearing support in quieter settings like one-on-one conversations at home, and who value discreet, in-ear styling with reliable feedback control. Those frequently navigating noisy environments or wanting to stream music and calls should explore alternatives.

Test Configuration

Documentation of Zepp Clarity One Lab Testing Parameters

Our engineers recorded the specific settings, firmware version, and test conditions used during the Zepp Clarity One evaluation. The notes below provide transparency into how we configured the device for measurement.

Lab Notes

Initial fit observations

In its out-of-box configuration with an open dome, the Zepp Clarity One achieved a normalized Initial Score of 3.9/5. Speech in quiet performed solidly at 3.5/5, while own-voice comfort was strong at 4.1/5. Feedback handling scored 4.2/5 initially. Speech in noise was limited at 1.6/5, and music streaming was not functional at 0.0/5. This initial setup provides accessible hearing support for quiet environments with minimal adjustment required.

Tuned fit observations

After professional tuning with a power dome with slits, the normalized Tuned Score improved slightly to 4.0/5. Speech in quiet increased to 3.7/5, and feedback handling reached an excellent 5.0/5. Own-voice comfort remained solid at 3.8/5. Speech in noise decreased slightly to 1.4/5, and music streaming remained at 0.0/5. The tuned configuration offers modest gains in speech clarity and feedback control while maintaining overall solid performance.
