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

Lexie B3
The Lexie B3 is a behind-the-ear OTC hearing aid priced at $999 that earns an A grade with a SoundScore of 4.8/5 in our lab testing. This places it at #1 among the 65 OTC hearing aids we've evaluated, making it a standout performer in its category. In our standardized testing, the Lexie B3 demonstrates excellent speech-in-quiet performance at 4.5/5, scoring 1.73 points above the OTC category average of 2.79/5. Speech-in-noise results are more nuanced—while the 2.5/5 score sits 1.02 points above the category average of 1.48/5, this remains mixed in absolute terms. Music streaming quality is solid at 3.3/5, exceeding the category average by 1.38 points, and feedback handling is excellent at 4.6/5. Own-voice comfort scores a solid 3.0/5, sitting 0.49 points above the category average. The device uses a tulip dome coupling in both initial and tuned configurations, maintaining consistent performance across fitting conditions with identical normalized scores of 4.8/5 for both fits. For those considering alternatives, devices like the RxEars Rxi, Meta Ray-Ban Glasses (Gen 2), and Cearvol Wave offer lower price points, though with correspondingly lower SoundScores. The Lexie B3 is best suited for consumers seeking top-tier OTC sound performance who prioritize speech clarity in quieter environments and quality music streaming, and who can accommodate its mid-tier OTC price point.
