Eargo 5 vs Sontro Soundwave
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.

Sontro Soundwave
The Sontro Soundwave is a mid-priced OTC hearing aid priced at $849, earning a B grade with a SoundScore of 3.1/5 in HearAdvisor's lab testing. This behind-the-ear device uses disposable batteries and ranks #61 of 65 OTC hearing aids tested, placing it in the top 92% of its category. In our lab testing, the Soundwave shows a notable strength in own-voice comfort, scoring 3.6/5—a solid result that sits 1.09 points above the category average. This suggests users may experience less of the "talking in a barrel" sensation that can occur with some hearing aids. However, the device faces challenges in other key areas. Speech in quiet scores 2.7/5 (mixed, 0.12 points below average), while speech in noise registers at 1.2/5 (low, 0.28 points below average), indicating potential difficulty in challenging listening environments. The most significant limitations appear in music streaming and feedback handling. Music streaming scores 0.0/5, falling 1.92 points below the category average—a notable weakness for users who value audio entertainment. Feedback handling scores 2.5/5, which is 2.04 points below the category average of 4.54/5, suggesting the device may be more prone to whistling issues. At this price point, competitors offer substantially stronger performance. Devices like the Sony CRE-E10 and Lexie B2 Plus deliver significantly higher sound scores in the same price range. The Sontro Soundwave may suit those prioritizing own-voice comfort over speech clarity and streaming quality, but most users would benefit from exploring higher-performing alternatives at similar or lower prices.
