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

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.
Choice

Eargo Link
The Eargo Link is a mid-priced OTC hearing aid released in 2024, earning an A grade with a SoundScore of 4.1/5 in our lab testing. At $799, it ranks #15 of 65 OTC hearing aids tested, placing it in the top 22% of the category. In our testing, the Eargo Link demonstrates notable strengths in music streaming, scoring 4.4/5—a strong result that sits 2.48 points above the category average. This makes it a standout choice for users who prioritize audio quality when streaming from their phone. Speech performance is solid, with speech in quiet measuring 3.2/5 (0.42 points above average) and speech in noise at 2.0/5 (0.54 points above average, though mixed in absolute terms). Feedback handling is excellent at 4.7/5. The main limitation is own-voice comfort, which scores 1.3/5—a low result that falls 1.21 points below the category average. Users sensitive to the sound of their own voice may find this challenging, particularly with the closed dome configuration used in the tuned fit. The Eargo Link supports both iPhone and Android streaming with hands-free capability and uses rechargeable batteries. It's best suited for those who value exceptional music streaming quality and solid speech clarity, and who can tolerate some own-voice occlusion. Competitors in this price range include higher-scoring options like the Yeasound RIC800 and Sony CRE-E10, though the Eargo Link's streaming performance remains a differentiator.
