Autiphon U0 Series

The Autiphon U0 Series is a budget amplification product available at $99, earning a B grade with a SoundScore of 3.0/5 in HearAdvisor's lab testing. This visible-in-ear device ranks #6 of 8 amplification products tested, placing it in the top 63% of its category. In our testing, the U0 Series demonstrates excellent feedback handling at 5.0/5, scoring 0.72 points above the category average. This means users can expect stable performance without the whistling issues that plague some amplifiers. Speech in quiet environments scores 2.3/5—above the category average by 0.22 points, though only mixed in absolute terms. The device shows notable limitations in other areas. Speech in noise performance is low at 1.0/5, falling 0.37 points below the category average, which may make challenging listening environments difficult. Music streaming is the weakest area at 0.0/5, coming in 1.16 points below category average—users seeking audio streaming functionality should look elsewhere. The Autiphon U0 Series is best suited for budget-conscious consumers who primarily need basic amplification in quieter settings and prioritize reliable, feedback-free operation over advanced features. The rechargeable batteries add convenience at this price point. However, those who frequently encounter noisy environments or want to stream music should consider alternatives despite the higher cost.

EargoSoundGrade B

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.
