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.

MDHearing VoltMax

The MDHearing VoltMax is a behind-the-ear OTC hearing aid priced at $699, earning a B grade with a SoundScore of 3.0/5 in our lab testing. This mid-priced device ranks #62 of 65 in the OTC Hearing Aid category, placing it in the bottom portion of tested products. In our standardized testing, the VoltMax demonstrates excellent feedback handling at 5.0/5, scoring 0.46 points above the category average. This means users are unlikely to experience whistling or squealing during typical wear. However, speech performance presents significant challenges—speech in quiet scores a low 1.9/5 (0.93 points below average), while speech in noise scores 1.0/5 (0.48 points below average). These results suggest limited benefit for understanding conversation in both calm and challenging listening environments. Music streaming is a notable weakness, scoring 0.0/5 and falling 1.92 points below the category average. Users who prioritize streaming audio content from their phones should consider alternatives. Own-voice comfort is mixed at 2.4/5, roughly matching the category average. At this price point, several alternatives offer substantially stronger performance. Devices like the Yeasound RIC800 and Sony CRE-E10 score above 4.5/5 at similar or lower prices. The VoltMax may appeal to users who prioritize feedback-free wear and basic amplification with rechargeable convenience, but those seeking stronger speech clarity should explore higher-performing options in this price range.
