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

Eargo 8
The Eargo 8 is a premium-priced OTC hearing aid ($2,399) that earns a B grade with a SoundScore of 3.3/5 in our lab testing. This invisible-in-ear device represents Eargo's 2025 flagship offering, featuring a rechargeable design that sits completely within the ear canal. In our testing, the Eargo 8 showed mixed performance across key metrics. Speech clarity in quiet environments is a relative strength, scoring 0.27 points above the OTC category average. Own-voice comfort also performs well, measuring 0.69 points above average at 3.2/5—a solid result that suggests reduced occlusion effects during conversation. However, speech understanding in noisy environments scored 1.2/5, which is both low in absolute terms and 0.27 points below the category average. The most significant limitation we measured was music streaming, which scored 0.0/5—nearly 2 points below the OTC average. This makes the Eargo 8 unsuitable for users who prioritize streaming audio quality. Feedback handling is strong in absolute terms at 4.2/5, though slightly below the category average. At its premium price point, the Eargo 8 faces stiff competition. Several devices in our database deliver comparable or better sound performance at lower prices, including alternatives from Eargo's own lineup. The Eargo 8 is best suited for users who prioritize invisible cosmetics and own-voice comfort over streaming capability and value, and who primarily need help hearing speech in quieter settings.

Signia Active Pro IX
The Signia Active Pro IX is a premium prescription hearing aid with a visible-in-ear design, priced at $3,199. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.6/5, ranking #8 among 39 prescription hearing aids tested. This device delivers strong speech clarity performance. Speech in quiet scores 4.3/5, which is +0.85 points above the category average—a notable strength for everyday conversations. Speech in noise measures 2.9/5, which is +0.74 points above the category average, though the absolute score reflects mixed performance in challenging listening environments. Own-voice comfort scores a solid 3.3/5, sitting +0.60 points above average, suggesting reasonable naturalness for wearers. Music streaming quality is mixed at 2.9/5, only slightly above the category average (+0.14 points). Feedback handling scores 3.4/5—solid in absolute terms but -1.32 points below the category average of 4.72/5, indicating this device may be more prone to feedback than typical prescription aids in our standardized tests. The Active Pro IX features rechargeable batteries and supports both iPhone and Android streaming with hands-free capability. It earned HearAdvisor's 2024 Expert's Choice Award. Buyers in this premium price tier should note that competitors like the Phonak Sphere Infinio and Oticon Intent score higher overall. Those seeking similar performance at lower cost may want to explore options like the Rexton Reach R-Li T80 at Costco.
