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

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.

Sony CRE-C20
The Sony CRE-C20 is an invisible-in-ear OTC hearing aid priced at $999, earning a B grade with a SoundScore of 3.6/5 in our lab testing. This mid-priced device offers a discreet form factor with rechargeable batteries, positioning it in the upper tier of the OTC market. In our testing, the CRE-C20 demonstrates notable strengths in speech clarity. Speech in quiet scores 4.1/5—a strong result that sits 1.33 points above the OTC category average. Speech in noise performance reaches 2.7/5, which is 1.24 points above the category average, though only mixed in absolute terms. Own voice comfort scores 2.9/5, slightly above average for the category at +0.39 points. The device shows significant limitations in other areas. Music streaming scored 0.0/5, falling 1.92 points below the category average—this invisible-in-ear design does not support audio streaming functionality. Feedback handling registers at 3.9/5, which is solid in absolute terms, though 0.64 points below the category average of 4.54/5. The CRE-C20 demonstrates meaningful improvement with proper adjustment. The normalized Initial Score of 3.4/5 improves to 4.2/5 when tuned, suggesting users who invest time in optimization will see better results. Within its price range, alternatives like the Sony CRE-E10 (4.69/5) and Lexie B2 Plus (4.43/5) score higher overall. The CRE-C20 is best suited for users prioritizing discretion and speech clarity who don't need music streaming capabilities.
