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

MDHearing Neo XS
The MDHearing Neo XS is a budget-priced OTC hearing aid in the invisible-in-ear style, available for $397. In HearAdvisor lab testing, it earned a C grade with a SoundScore of 2.9/5, ranking #63 of 65 OTC hearing aids tested. Performance results reveal a mixed profile. The Neo XS shows strength in own-voice comfort, scoring 3.2/5—0.69 points above the category average—meaning wearers may experience less of the "boomy" quality that can accompany hearing aid use. Feedback handling is excellent at 5.0/5, sitting 0.46 points above average, so users should experience stable performance without whistling during typical wear. However, speech clarity is a significant limitation. Speech in quiet scores just 1.0/5, falling 1.77 points below the OTC category average. Speech in noise also scores 1.0/5, 0.48 points below average. Music streaming scored 0.0/5, which is 1.92 points below the category average—this device is not suited for audio entertainment. At this price point, several alternatives offer notably stronger performance. The Elehear Beyond (4.36/5), Apple AirPods Pro 2 (4.06/5), and Zepp Clarity Omni (3.88/5) all deliver better overall sound quality in the same price range. The Neo XS may appeal to those prioritizing own-voice comfort and feedback stability over speech intelligibility, but most users seeking meaningful hearing benefit should consider higher-scoring options.

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.
