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

Eargo 6
The Eargo 6 is a premium-priced OTC hearing aid ($2,250) that earned a B grade and a SoundScore of 3.4/5 in our lab testing, placing it in the top 63% of OTC hearing aids we've evaluated. This invisible-in-ear device delivers solid speech clarity in quiet environments, scoring 3.3/5—notably 0.53 points above the OTC category average. Own-voice comfort is also above average at 2.9/5, though mixed in absolute terms. However, the Eargo 6 shows significant weaknesses in challenging listening situations, with speech-in-noise performance scoring just 1.0/5, falling 0.48 points below the category average. The most notable limitation is music streaming, which scored 0.0/5 in our testing—substantially below the category average. Feedback handling scored 3.3/5, solid in absolute terms but 1.24 points below the OTC average of 4.54/5. The device uses rechargeable batteries and maintains a fully invisible profile when worn. The Eargo 6 may suit consumers who prioritize discreet aesthetics and primarily need help hearing conversations in quieter settings. However, shoppers should note that alternatives like the Sony CRE-C10 and Olive Union Air achieved higher SoundScores at lower price points. Those frequently in noisy environments or who value music streaming should explore other options.
