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 earns a B grade with a SoundScore of 3.4/5 in our lab testing. This invisible-in-ear device ranks #42 of 65 OTC hearing aids tested, placing it in the top 63% of its category. In our standardized testing, the Eargo 6 demonstrates solid speech clarity in quiet environments, scoring 3.3/5—notably 0.53 points above the OTC category average. Own-voice comfort also performs above category average at 2.9/5, which may benefit users sensitive to the sound of their own voice. However, the device shows limitations in challenging listening situations, with speech-in-noise performance scoring 1.0/5, falling 0.48 points below the category average. A significant limitation is music streaming, which scores 0.0/5—well below the category average by 1.92 points. Users who prioritize streaming audio content should consider alternatives. Feedback handling scores 3.3/5, which is solid in absolute terms though 1.24 points below the category average of 4.54/5. The Eargo 6 may appeal to users prioritizing a completely invisible form factor and solid quiet-environment performance. However, at its premium price point, alternatives like the Sony CRE-C10 offer stronger overall performance at a lower price. The rechargeable battery adds convenience, but buyers should weigh the device's limitations in noise and streaming against its aesthetic benefits.
Choice

Lucid Ultra 128
The Lucid Ultra 128 is a premium behind-the-ear prescription hearing aid priced at $5,000, earning an A grade with a SoundScore of 4.4/5 in our lab testing. It ranks #17 among 39 prescription hearing aids tested, placing it in the top 41% of its category. Speech performance is where the Lucid Ultra 128 truly excels.

Speech in noise performance reached 2.7/5, which sits above the category average by 0.59 points, though it remains mixed in absolute terms. This suggests the device handles conversational clarity well in our test scenarios, particularly in quieter environments. The device does face some challenges. Feedback handling scored just 1.7/5, falling 3.02 points below the category average of 4.72/5—a notable weakness compared to other prescription aids in our testing.

At this price point, several competitors in our database achieved higher overall scores, including the Phonak Sphere Infinio and Oticon Intent. The Lucid Ultra 128 features disposable batteries and supports both iPhone and Android streaming. It may appeal to users who prioritize speech clarity in quiet settings and are less concerned about feedback stability or music streaming fidelity in our standardized tests.
