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

Eargo 5
The Eargo 5 is a premium-priced OTC hearing aid ($1,450) that earns a B grade with a SoundScore of 3.6/5 in our lab testing. This invisible-in-ear device offers a discreet rechargeable design, though its acoustic performance shows notable strengths and weaknesses compared to alternatives in its price range. In our testing, the Eargo 5 demonstrates solid speech-in-quiet performance at 3.5/5, scoring 0.75 points above the OTC category average. Own-voice comfort also measures above average, which may appeal to users sensitive to occlusion effects. However, speech-in-noise performance is low at 1.4/5, and music streaming scores 0.0/5—significantly below the category average of 1.92/5. Users who prioritize phone streaming or frequently encounter noisy environments should consider these limitations. Feedback handling is strong in absolute terms at 4.2/5, though slightly below the category average of 4.54/5. The device uses closed sleeves for ear coupling in both initial and tuned configurations, with minimal score improvement from tuning (3.6 to 3.7/5). At this price point, competitors like the Lucid Tala (4.63/5) and Audicus Omni 2 (4.61/5) offer substantially higher overall sound performance. Budget-conscious shoppers may also find similar or better sound quality from lower-priced options like the Sony CRE-C10. The Eargo 5 may suit users who prioritize invisible cosmetics and quiet-environment listening over streaming and noise performance.

Sennheiser All-Day Clear Slim
The Sennheiser All-Day Clear Slim is a premium behind-the-ear OTC hearing aid priced at $1,499, earning an A grade with a SoundScore of 4.1/5 in our lab testing. This places it in the top 23% of the OTC hearing aid category, ranking #16 among 65 tested devices. In our testing, the All-Day Clear Slim demonstrates notable strengths in music streaming, scoring 3.8/5—a solid result that sits 1.88 points above the category average. This makes it one of the stronger performers for users who prioritize audio quality when streaming from their phone. Feedback handling is excellent at 5.0/5, measuring 0.46 points above the category average, meaning users can expect stable performance without whistling during typical daily activities. Speech clarity in quiet environments is solid at 3.6/5, coming in 0.85 points above the category average. However, speech in noise performance is low at 1.5/5, matching the category average—a common limitation across OTC devices. Own-voice comfort scores 1.9/5, which is 0.61 points below the category average, suggesting some users may notice their own voice sounds different or hollow. The All-Day Clear Slim includes rechargeable batteries and supports streaming to both iPhone and Android devices with hands-free functionality. At its price point, alternatives like the Lucid Tala and Audicus Omni 2 offer higher overall scores, though the Sennheiser may appeal to those who value the brand's audio heritage and prioritize music streaming quality over speech-in-noise performance.
