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 Pure C&G BCT IX
The Signia Pure C&G BCT IX is a premium behind-the-ear prescription hearing aid released in 2025, earning an A grade with a SoundScore of 4.4/5 in our lab testing. Priced at $3,398, it ranks #16 among 39 prescription hearing aids tested. In our standardized testing, this device demonstrates particular strength in own-voice comfort, scoring 3.8/5—a solid result that sits 1.10 points above the category average. This makes it a noteworthy option for users who prioritize natural sound quality when speaking. Speech clarity also performs well, with speech-in-quiet at 3.8/5 (+0.39 points above average) and speech-in-noise at 2.5/5 (+0.43 points above average), though the latter remains mixed in absolute terms despite beating the category benchmark. Feedback handling presents an interesting picture: at 4.2/5, it's strong in absolute terms, though it falls 0.52 points below the category average of 4.72/5. Music streaming scores 2.7/5, essentially matching the category average. The device features rechargeable batteries, iPhone and Android streaming, and hands-free functionality. While the Pure C&G BCT IX delivers solid overall performance, shoppers in this premium price tier should note that competitors like the Phonak Sphere Infinio and Oticon Intent score higher in our testing. Budget-conscious buyers may also find comparable sound quality at lower price points from options like the Rexton Reach R-Li T80 at Costco. This hearing aid is best suited for users who value own-voice naturalness and reliable speech clarity in everyday listening situations.
