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

Linner Mercury
The Linner Mercury is a budget OTC hearing aid priced at $387, earning a B grade with a SoundScore of 3.0/5 in our lab testing. This visible-in-ear style device ranks #60 of 65 in the OTC Hearing Aid category, positioning it in the lower tier of available options. In our standardized testing, the Mercury demonstrates excellent feedback handling at 4.7/5, scoring 0.16 points above the category average. This means users are unlikely to experience whistling or squealing during typical wear. However, the device shows limitations in other key areas. Speech in quiet scores 2.2/5, falling 0.62 points below the category average, while speech in noise performance is low at 1.0/5, sitting 0.48 points below average. Own-voice comfort is also low at 1.6/5, measuring 0.91 points below the category average. The most significant limitation is music streaming, which scores 0.0/5—a full 1.92 points below the category average. Users who plan to stream phone calls or music through their hearing aids should consider alternatives. At this price point, competitors like the Elehear Beyond and Apple AirPods Pro 2 offer substantially higher overall scores. The Linner Mercury may suit budget-conscious first-time users who prioritize stable, feedback-free wear over streaming capabilities or challenging listening environments. However, those seeking better speech clarity or music quality should explore other options in this price range.
Choice

Yeasound RIC700
The Yeasound RIC700 is a budget-priced OTC hearing aid that delivers A-grade performance in HearAdvisor's lab testing, placing it in the top 14% of the 65 OTC devices we've evaluated. At $399, it offers strong value for consumers seeking quality amplification without prescription-level costs. In our testing, the RIC700 excels at speech clarity in quiet environments, scoring 4.2/5—a strong result that sits 1.41 points above the OTC category average. Speech understanding in noisy settings scores 1.9/5, which is above the category average but remains low in absolute terms, a common limitation across OTC devices. Music streaming quality reaches 2.9/5, nearly a full point above the category average, though still mixed overall. Feedback handling is excellent at 4.6/5. The device does show some limitations. Own-voice comfort scores 2.0/5, falling 0.51 points below the category average—users may notice some occlusion effects when speaking. This behind-the-ear style features rechargeable batteries and supports both iPhone and Android streaming with hands-free capability. The RIC700 competes well within its price bracket, though shoppers should note that the higher-ranked Yeasound RIC800 and Sony CRE-E10 are available at similar price points with stronger overall scores. For budget-conscious consumers prioritizing speech clarity in quieter listening situations, the RIC700 represents a solid option in the OTC market.
