Eargo 5 vs Phonak Audéo EON Sphere
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.

Phonak Audéo EON Sphere
The Phonak Audéo EON Sphere is a premium behind-the-ear prescription hearing aid priced at $4,398. In HearAdvisor's lab testing, it earned a SoundScore of 5.0/5 and an A grade, placing it among the top performers in the prescription hearing aid category. Speech performance stands out as this device's greatest strength. Speech in noise scored an excellent 4.5/5, a full 2.53 points above the category average of 1.96/5—a substantial margin that makes this one of the strongest performers in challenging listening environments. Speech in quiet also performed well at 4.3/5, nearly a full point above the category average. These results suggest the Audéo EON Sphere may be particularly well-suited for users who frequently encounter noisy social settings or group conversations. Music streaming delivered a solid 3.7/5, more than a point above the category average of 2.64/5, indicating above-average audio fidelity for phone-streamed content. Own-voice comfort scored 2.8/5, which sits just above the category average but reflects mixed absolute performance—users sensitive to occlusion effects should discuss this with their hearing care provider. Feedback handling scored an excellent 4.6/5 in absolute terms, though it lands slightly below the category average of 4.71/5. The Audéo EON Sphere represents Phonak's latest premium technology and delivers strong results across most metrics in our standardized testing. It's best suited for users prioritizing speech clarity in difficult listening situations who are prepared for the premium price point.
