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.

Oticon Zeal

The Oticon Zeal is a premium invisible-in-ear prescription hearing aid priced at $4,798. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.7/5, placing it in the top 11% of prescription hearing aids tested and ranking #5 of 36 devices in its category. Speech performance is where the Zeal truly excels. It achieved an excellent 4.9/5 in speech-in-quiet testing, scoring 1.56 points above the category average—among the strongest results we've measured. Speech-in-noise performance is solid at 3.0/5, which is 1.08 points above the category average of 1.96/5, making it notably better than typical prescription aids in challenging listening environments. Music streaming quality scores 3.3/5, sitting 0.66 points above category average and providing solid fidelity for phone audio. However, the Zeal shows some limitations in other areas. Own-voice comfort is mixed at 2.0/5, falling 0.75 points below the category average—users sensitive to how their own voice sounds may notice this. Feedback handling, while solid in absolute terms at 3.3/5, measures 1.41 points below the category average of 4.71/5. The Zeal is best suited for users who prioritize outstanding speech clarity in both quiet and moderately noisy settings, and who value quality audio streaming. Those particularly sensitive to own-voice perception or who need maximum feedback stability may want to discuss these tradeoffs with their hearing care provider.
