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.

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.
