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.

Olive Union Max
The Olive Union Max is a budget-priced OTC hearing aid released in 2024, earning a B grade with a SoundScore of 3.5/5 in HearAdvisor's lab testing. At $190, it positions itself as an affordable entry point into the OTC hearing aid market. In our testing, the Max demonstrates a distinctive performance profile with notable strengths in music streaming and feedback handling. The music streaming score of 4.0/5 is strong in absolute terms and stands out at 2.08 points above the OTC category average—making it one of the better options for users who prioritize phone audio quality. Feedback handling is excellent at 5.0/5, sitting 0.46 points above average, meaning users can expect stable performance without whistling during typical wear. However, speech performance presents limitations. Speech in quiet scores a mixed 2.6/5, falling 0.21 points below the category average. More notably, speech in noise is low at 1.0/5, which is 0.48 points below average—a meaningful gap for users who need help understanding conversation in challenging environments. Own-voice comfort is also low at 1.6/5, trailing the category average by 0.91 points, which may result in noticeable occlusion effects. The Olive Union Max may suit budget-conscious consumers who prioritize music and media streaming over speech clarity in difficult listening situations. Those who frequently navigate noisy environments or need stronger speech support may want to consider alternatives with better speech-in-noise performance.
