Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Lexie Lumen
The Lexie Lumen is a budget-priced OTC hearing aid available for $299, earning a B grade with a SoundScore of 3.4/5 in our lab testing. This behind-the-ear device ranks #40 among 65 OTC hearing aids tested, placing it in the top 60% of its category. In our testing, the Lumen demonstrates mixed speech performance. Speech in quiet scores 2.5/5, falling 0.24 points below the category average. Speech in noise performs better at 2.0/5, which is 0.55 points above the category average—though this remains mixed in absolute terms. Where the device excels is feedback handling, achieving a perfect 5.0/5, which is 0.46 points above the already-strong category average of 4.54/5. The most significant limitation is music streaming, which scores 0.0/5—a full 1.92 points below the category average. Users who prioritize streaming audio from their phones should look elsewhere. The device uses disposable batteries rather than rechargeables. At this price point, buyers face a competitive landscape. Several alternatives in the same price range deliver substantially higher scores, with some reaching into the 4.2-4.7 range. The Lexie Lumen may suit budget-conscious consumers who prioritize stable, feedback-free amplification over streaming capabilities and don't require top-tier speech clarity. However, those willing to explore other options at similar prices may find significantly better overall performance.

Olive Union Air
The Olive Union Air is a budget-priced OTC hearing aid that earned a B grade with a SoundScore of 3.9/5 in our lab testing, placing it in the top 31% of OTC hearing aids at #21 of 65 devices tested. At $250, it represents a competitive entry point in the over-the-counter hearing aid market. In our testing, this visible-in-ear style device demonstrated notable strengths in music streaming, scoring 3.6/5—a solid result that sits 1.67 points above the OTC category average. Feedback handling was excellent at 5.0/5, meaning users should experience minimal whistling or squealing during normal use. Speech understanding in quiet environments also performed well at 3.3/5, measuring 0.46 points above the category average. The Olive Union Air does show limitations in more challenging listening situations. Speech in noise scored 1.0/5, falling 0.48 points below the category average—a common weakness among budget OTC devices that may affect conversations in restaurants or busy environments. Own-voice comfort measured 2.2/5, slightly below average, which some users may notice when speaking. This device is best suited for individuals who prioritize music and media streaming, need reliable feedback control, and primarily listen in quieter environments. Those who frequently encounter noisy social situations may want to consider devices with stronger speech-in-noise performance.
