Eargo 5 vs iBstone AuraLink
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.

iBstone AuraLink
The iBstone AuraLink is a mid-priced OTC hearing aid released in 2024, earning a B grade with a SoundScore of 3.6/5 in HearAdvisor's lab testing. This behind-the-ear device ranks #33 among 65 tested OTC hearing aids, placing it in the top 49% of its category. In our testing, the AuraLink shows a distinctive performance profile with notable strengths in audio entertainment. Music streaming scored a solid 3.6/5, measuring 1.68 points above the category average—a standout result for an OTC device. Feedback handling earned an excellent 5.0/5, sitting 0.46 points above average, meaning users should experience minimal whistling during daily wear. However, speech clarity presents a different picture. Speech in quiet scored a mixed 2.3/5, falling 0.47 points below the category average of 2.79. Speech in noise performance was low at 1.0/5, trailing the already modest category average by 0.48 points. Own-voice comfort scored 2.7/5, slightly above average but only mixed in absolute terms. At $649, the AuraLink faces competition from alternatives offering similar or better sound performance at lower prices, including the iHear MatriX and Olive Union Max. The AuraLink may appeal to users who prioritize music and media streaming over speech enhancement, but those seeking stronger speech clarity should explore other options in this price range.
