Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Eargo 8
The Eargo 8 is a premium-priced OTC hearing aid featuring an invisible-in-ear design with rechargeable batteries, priced at $2,399. In our lab testing, it earned a B grade with a SoundScore of 3.4/5, placing it in the top 71% of the OTC Hearing Aid category. Sound performance presents a mixed picture. The Eargo 8 delivers solid speech-in-quiet performance at 3.1/5, scoring 0.27 points above the category average—making it a reasonable choice for conversational settings without background noise. Own-voice comfort is another strength, measuring 0.69 points above average at 3.2/5, which may appeal to users who are sensitive to hearing their own voice through hearing aids. Feedback handling is strong in absolute terms at 4.2/5, though slightly below the category average. However, the device shows notable weaknesses in challenging listening environments. Speech-in-noise performance is low at 1.2/5, falling 0.27 points below the category average—users who frequently encounter noisy restaurants, busy offices, or social gatherings may find this limiting. Music streaming scored 0.0/5, significantly below the category average, making this device unsuitable for users who prioritize audio entertainment through their hearing aids. The Eargo 8 is best suited for users who prioritize discreet, invisible-in-ear styling and primarily need assistance in quieter conversational settings. However, at this premium price point, buyers should be aware that similarly-priced alternatives and even some lower-cost options may offer comparable or better overall sound performance.

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.
