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

iHear MatriX
The iHear MatriX is a behind-the-ear OTC hearing aid priced at $499, earning a B grade with a SoundScore of 3.8/5 in our lab testing. This places it in the top 40% of OTC hearing aids, offering solid performance at a budget-friendly price point. In our testing, the MatriX demonstrated notable strengths in speech intelligibility. Speech in quiet scored a solid 4.0/5, measuring 1.17 points above the category average. Speech in noise performance came in at 2.4/5—above the category average by 0.96 points, though only mixed in absolute terms. Feedback handling was excellent at 5.0/5, surpassing the already-strong category average by 0.46 points, meaning users can expect reliable stability without whistling during typical wear. The most significant limitation is music streaming, which scored 0.0/5—a full 1.92 points below the category average. Users who prioritize streaming audio from their phone should consider alternatives. Own-voice comfort measured 2.7/5, slightly above category average but still mixed in absolute terms. The MatriX features rechargeable batteries and supports streaming from both iPhone and Android devices. With a normalized Initial Score of 3.7/5 improving to 4.3/5 after tuning, this hearing aid responds well to optimization. It's best suited for users who prioritize speech clarity and feedback-free wear over music streaming quality, and who want a budget OTC option that delivers above-average speech performance in our lab framework.

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.
