Choice

Eargo Link
The Eargo Link is a mid-priced OTC hearing aid released in 2024, earning an A grade with a SoundScore of 4.1/5 in our lab testing. At $799, it ranks #15 of 65 OTC hearing aids tested, placing it in the top 22% of the category. In our testing, the Eargo Link demonstrates notable strengths in music streaming, scoring 4.4/5—a strong result that sits 2.48 points above the category average. This makes it a standout choice for users who prioritize audio quality when streaming from their phone. Speech performance is solid, with speech in quiet measuring 3.2/5 (0.42 points above average) and speech in noise at 2.0/5 (0.54 points above average, though mixed in absolute terms). Feedback handling is excellent at 4.7/5. The main limitation is own-voice comfort, which scores 1.3/5—a low result that falls 1.21 points below the category average. Users sensitive to the sound of their own voice may find this challenging, particularly with the closed dome configuration used in the tuned fit. The Eargo Link supports both iPhone and Android streaming with hands-free capability and uses rechargeable batteries. It's best suited for those who value exceptional music streaming quality and solid speech clarity, and who can tolerate some own-voice occlusion. Competitors in this price range include higher-scoring options like the Yeasound RIC800 and Sony CRE-E10, though the Eargo Link's streaming performance remains a differentiator.

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.
