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

HearingAssist Control
The HearingAssist Control is a behind-the-ear OTC hearing aid priced at $549, earning a B grade with a SoundScore of 3.3/5 in our lab testing. This places it in the lower portion of the OTC category, ranking #51 of 65 devices tested. In our testing, the Control demonstrates notable strengths in speech performance. Speech in quiet scores 0.59 points above the category average at 3.4/5, representing solid absolute performance. Speech in noise comes in at 2.0/5—above the category average by 0.56 points, though only mixed in absolute terms. Feedback handling is excellent at 5.0/5, meaning the device remained stable without audible squealing during our standardized challenge tests. The device shows significant weaknesses in other areas. Music streaming scored 0.0/5, which is 1.92 points below the category average and indicates this device does not support or perform well with phone audio streaming. Own-voice comfort is also below average at 2.1/5 (0.41 points below category average), which may be noticeable during extended conversations. The HearingAssist Control may suit users who prioritize speech clarity over streaming functionality and who don't require premium sound quality across all use cases. However, buyers in this price range should note that several competitors—including the Yeasound RIC800 and Sony CRE-E10—deliver substantially higher overall scores. Those seeking similar speech performance at a lower cost may also consider the iHear MatriX.

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.
