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.

Signia Styletto C&G IX
The Signia Styletto C&G IX is a premium prescription behind-the-ear hearing aid released in 2024, priced at $3,398. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.6/5, placing it in the top 25% of prescription hearing aids and ranking #10 of 36 devices in its category. This device demonstrates strong performance across most sound quality metrics in our testing. Speech in quiet scored 3.9/5, which is 0.62 points above the category average of 3.32/5. Speech in noise came in at 2.5/5—above the category average by 0.58 points, though only mixed in absolute terms. Own-voice comfort was a particular strength at 3.7/5, exceeding the category average by 0.95 points. Music streaming quality scored a solid 3.1/5, sitting 0.46 points above the category average. However, feedback handling measured 3.6/5, which while solid in absolute terms, falls 1.11 points below the category average of 4.71/5. This represents the device's primary weakness relative to competitors. The Styletto C&G IX features rechargeable batteries, iPhone and Android streaming, and hands-free calling capability. It has earned HearAdvisor's Expert's Choice Award in both 2023 and 2024. Consumers seeking similar sound performance at lower prices may want to compare the Rexton Reach R-Li T80 at Costco or the Lexie B2 Plus. This device is best suited for those prioritizing speech clarity and own-voice comfort who can accept slightly below-average feedback performance.
