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 Air
The Olive Union Air is a budget-priced OTC hearing aid that earns an A grade with a SoundScore of 4.0/5 in our lab testing, placing it in the top 31% of OTC devices. At $250, it offers strong value for consumers seeking an affordable entry into hearing amplification. In our testing, the Olive Union Air demonstrates notable strengths in music streaming, scoring 3.6/5—a solid 1.67 points above the OTC category average. This makes it a standout choice for users who prioritize phone audio and media consumption. Speech understanding in quiet environments also performs well at 3.3/5, sitting 0.46 points above the category average. Feedback handling is excellent at 5.0/5, meaning users can expect stable performance without whistling during normal use. The device shows limitations in challenging listening situations. Speech in noise scores 1.0/5, falling 0.48 points below the category average—a common weakness among budget OTC devices that may frustrate users in restaurants or group conversations. Own-voice comfort is mixed at 2.2/5, slightly below the category average, which some users may notice when speaking. The Olive Union Air is best suited for budget-conscious consumers who primarily need amplification in quieter settings and value strong streaming audio quality. Those who frequently encounter noisy environments may want to consider alternatives with better noise performance.
