EargoSoundGrade B

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.

Signia Styletto AX

The Signia Styletto AX is a premium prescription behind-the-ear hearing aid released in 2022, priced at $4,398. In HearAdvisor's lab testing, it earns an A grade with a SoundScore of 4.3/5, ranking #19 among 36 prescription hearing aids tested. This device demonstrates strong speech-in-quiet performance at 4.0/5, scoring 0.71 points above the category average. Speech-in-noise shows mixed absolute results at 2.3/5, though this still sits 0.32 points above the category average of 1.96/5. Music streaming quality is solid at 3.1/5, exceeding the category average by 0.46 points—a meaningful advantage for users who frequently stream audio from their iPhone. Own-voice comfort scores a solid 3.0/5, slightly above category average. However, feedback handling at 3.9/5 falls 0.81 points below the category average of 4.71/5—solid in absolute terms but notably weaker than many prescription competitors in our testing. The Styletto AX has earned HearAdvisor's Expert's Choice Award in both 2023 and 2024. With its distinctive slim design, rechargeable batteries, and iPhone streaming capabilities, it may appeal to users prioritizing aesthetics and convenience alongside strong speech clarity in quieter environments. Those frequently in challenging noise situations or requiring maximum feedback stability may want to compare alternatives in this price tier.
