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.

Zepp Clarity Omni
The Zepp Clarity Omni is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.9/5 in HearAdvisor's lab testing, placing it in the top 37% of OTC devices. At $399, this behind-the-ear rechargeable device offers solid overall performance with some standout strengths. The Omni's most impressive feature is its music streaming quality, scoring 3.6/5—a full 1.68 points above the OTC category average. This makes it one of the better choices for users who prioritize streaming audio from their iPhone or Android device. Feedback handling is excellent at 5.0/5, meaning users can expect stable performance without whistling during typical daily activities. Speech performance shows a more nuanced picture. Speech in quiet scores a solid 3.0/5, sitting 0.21 points above category average. Speech in noise, however, scores 1.9/5—above the category average by 0.40 points, but still low in absolute terms. Users in challenging listening environments like busy restaurants should set realistic expectations. Own-voice comfort scores 2.7/5, above category average but only mixed in absolute terms. The Zepp Clarity Omni is best suited for budget-conscious consumers who value excellent streaming audio quality and reliable feedback control, and who primarily need hearing support in quieter environments. Those frequently encountering noisy settings may want to consider alternatives with stronger speech-in-noise performance.
