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.
