Eargo 8

The Eargo 8 is a premium-priced OTC hearing aid featuring an invisible-in-ear design with rechargeable batteries, priced at $2,399. In our lab testing, it earned a B grade with a SoundScore of 3.4/5, placing it in the top 71% of the OTC Hearing Aid category. Sound performance presents a mixed picture. The Eargo 8 delivers solid speech-in-quiet performance at 3.1/5, scoring 0.27 points above the category average—making it a reasonable choice for conversational settings without background noise. Own-voice comfort is another strength, measuring 0.69 points above average at 3.2/5, which may appeal to users who are sensitive to hearing their own voice through hearing aids. Feedback handling is strong in absolute terms at 4.2/5, though slightly below the category average. However, the device shows notable weaknesses in challenging listening environments. Speech-in-noise performance is low at 1.2/5, falling 0.27 points below the category average—users who frequently encounter noisy restaurants, busy offices, or social gatherings may find this limiting. Music streaming scored 0.0/5, significantly below the category average, making this device unsuitable for users who prioritize audio entertainment through their hearing aids. The Eargo 8 is best suited for users who prioritize discreet, invisible-in-ear styling and primarily need assistance in quieter conversational settings. However, at this premium price point, buyers should be aware that similarly-priced alternatives and even some lower-cost options may offer comparable or better overall sound performance.

Resound Vivia 9 60S microRIE

The Resound Vivia 9 60S microRIE is a premium prescription behind-the-ear hearing aid released in 2025, currently available at $3,798. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.9/5, ranking #27 of 36 prescription hearing aids tested. This device demonstrates a mixed performance profile in our testing. Own-voice comfort is a notable strength, scoring 3.4/5—a solid result that sits 0.65 points above the category average, which may appeal to users sensitive to the hollow or boomy sound of their own speech. Speech clarity in quiet environments also performs well at 3.4/5, slightly above the category average. However, the Vivia 9 shows significant limitations in challenging listening situations. Speech in noise scored just 1.1/5, falling 0.81 points below the prescription hearing aid average—a substantial gap that suggests difficulty in restaurants, group conversations, or other noisy environments. Feedback handling, while strong in absolute terms at 4.2/5, still lands 0.51 points below what we typically see from prescription devices. Music streaming quality is mixed at 2.6/5, essentially matching the category average. At this premium price point, the Vivia 9 faces stiff competition. Several same-priced alternatives, including the Phonak Sphere Infinio and Oticon Intent, achieved notably higher overall scores in our testing. Consumers prioritizing noise performance may want to explore these options or consider lower-priced alternatives like the Sennheiser All Day Clear that delivered stronger overall results in our lab.
