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.

HearingAssist Eaze
The HearingAssist Eaze is a budget-priced OTC hearing aid released in 2023, earning a B grade with a SoundScore of 3.4/5 in our lab testing. At $399, it sits in the most affordable price tier of the OTC market, though it ranks #43 of 65 devices in its category. In our standardized testing, the Eaze demonstrates excellent feedback handling, scoring a perfect 5.0/5—0.46 points above the category average. This means users can expect stable performance without whistling during typical daily activities. However, the device shows limitations in other areas: speech clarity scores are mixed at 2.6/5 in quiet and low at 1.3/5 in noisy environments, both falling slightly below category averages. The most significant limitation is music streaming, which scored 0.0/5—nearly 2 points below the category average. Buyers who prioritize phone streaming for music or media should consider alternatives. Own-voice comfort is also mixed at 2.2/5, approximately 0.31 points below average for OTC devices. At this price point, shoppers have several higher-scoring alternatives to consider, including the Elehear Beyond and Apple AirPods Pro 2, which offer stronger overall performance. The HearingAssist Eaze may suit budget-conscious buyers who prioritize feedback stability over streaming capabilities and can accept modest speech performance in challenging listening situations.
