iBstoneSoundGrade B

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.

Oticon Zeal

The Oticon Zeal is a premium invisible-in-ear prescription hearing aid priced at $4,798. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.7/5, placing it in the top 11% of prescription hearing aids tested and ranking #5 of 36 devices in its category. Speech performance is where the Zeal truly excels. It achieved an excellent 4.9/5 in speech-in-quiet testing, scoring 1.56 points above the category average—among the strongest results we've measured. Speech-in-noise performance is solid at 3.0/5, which is 1.08 points above the category average of 1.96/5, making it notably better than typical prescription aids in challenging listening environments. Music streaming quality scores 3.3/5, sitting 0.66 points above category average and providing solid fidelity for phone audio. However, the Zeal shows some limitations in other areas. Own-voice comfort is mixed at 2.0/5, falling 0.75 points below the category average—users sensitive to how their own voice sounds may notice this. Feedback handling, while solid in absolute terms at 3.3/5, measures 1.41 points below the category average of 4.71/5. The Zeal is best suited for users who prioritize outstanding speech clarity in both quiet and moderately noisy settings, and who value quality audio streaming. Those particularly sensitive to own-voice perception or who need maximum feedback stability may want to discuss these tradeoffs with their hearing care provider.
