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

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.

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.
