HearingAssist Eaze vs Zepp Clarity One
Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

HearingAssist Eaze
The HearingAssist Eaze is a budget-priced OTC hearing aid released in 2023, earning a B grade with a SoundScore of 3.4/5 in our lab testing. At $399, it sits in the most affordable price tier of the OTC market, though it ranks #43 of 65 devices in its category. In our standardized testing, the Eaze demonstrates excellent feedback handling, scoring a perfect 5.0/5—0.46 points above the category average. This means users can expect stable performance without whistling during typical daily activities. However, the device shows limitations in other areas: speech clarity scores are mixed at 2.6/5 in quiet and low at 1.3/5 in noisy environments, both falling slightly below category averages. The most significant limitation is music streaming, which scored 0.0/5—nearly 2 points below the category average. Buyers who prioritize phone streaming for music or media should consider alternatives. Own-voice comfort is also mixed at 2.2/5, approximately 0.31 points below average for OTC devices. At this price point, shoppers have several higher-scoring alternatives to consider, including the Elehear Beyond and Apple AirPods Pro 2, which offer stronger overall performance. The HearingAssist Eaze may suit budget-conscious buyers who prioritize feedback stability over streaming capabilities and can accept modest speech performance in challenging listening situations.

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 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.
