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.

The Sony CRE-E10 is a mid-priced OTC hearing aid available at $998 that delivers excellent overall performance, earning an A grade and a SoundScore of 4.7/5 in our lab testing. This places it at #3 among 65 OTC hearing aids tested—in the top 3% of its category. In our testing, the CRE-E10 excels where it matters most for everyday communication. Speech in quiet scores a strong 4.3/5, measuring 1.46 points above the category average. Speech in noise performance is solid at 3.3/5, a full 1.77 points above average—a meaningful advantage for challenging listening environments. Music streaming is a particular standout at 4.0/5, scoring 2.08 points above the category average, making this an appealing choice for users who value audio quality beyond speech. The device does have limitations worth noting. Own-voice comfort scores low at 1.7/5, falling 0.81 points below the category average—users may notice their own voice sounds different or hollow. Feedback handling is solid in absolute terms at 3.4/5 but sits 1.14 points below the category average, so some users may experience occasional whistling in certain situations. The CRE-E10 is best suited for consumers who prioritize speech clarity and streaming quality and are comfortable with a visible in-ear style. With rechargeable batteries, iPhone streaming, and hands-free capability, it offers modern convenience. This device has earned HearAdvisor's Expert's Choice Award for three consecutive years (2023-2025), reflecting its consistent top-tier performance among OTC options.
