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.

Sontro Soundwave Hero
SontroSoundGrade B

Sontro Soundwave

The Sontro Soundwave is a mid-priced OTC hearing aid priced at $849, earning a B grade with a SoundScore of 3.1/5 in HearAdvisor's lab testing. This behind-the-ear device uses disposable batteries and ranks #61 of 65 OTC hearing aids tested, placing it in the top 92% of its category. In our lab testing, the Soundwave shows a notable strength in own-voice comfort, scoring 3.6/5—a solid result that sits 1.09 points above the category average. This suggests users may experience less of the "talking in a barrel" sensation that can occur with some hearing aids. However, the device faces challenges in other key areas. Speech in quiet scores 2.7/5 (mixed, 0.12 points below average), while speech in noise registers at 1.2/5 (low, 0.28 points below average), indicating potential difficulty in challenging listening environments. The most significant limitations appear in music streaming and feedback handling. Music streaming scores 0.0/5, falling 1.92 points below the category average—a notable weakness for users who value audio entertainment. Feedback handling scores 2.5/5, which is 2.04 points below the category average of 4.54/5, suggesting the device may be more prone to whistling issues. At this price point, competitors offer substantially stronger performance. Devices like the Sony CRE-E10 and Lexie B2 Plus deliver significantly higher sound scores in the same price range. The Sontro Soundwave may suit those prioritizing own-voice comfort over speech clarity and streaming quality, but most users would benefit from exploring higher-performing alternatives at similar or lower prices.
