The Audicus Omni 2 is a premium behind-the-ear OTC hearing aid priced at $1,898 that earned an A grade in our lab testing, placing it in the top 6% of the 65 OTC hearing aids we've evaluated. This two-time Expert's Choice Award winner (2023 and 2024) delivers consistently strong performance across multiple listening scenarios. In our testing, the Omni 2 demonstrated particular strength in speech clarity during quiet environments, scoring 4.2/5—a strong result that sits 1.38 points above the category average. Music streaming quality also impressed at 3.6/5, exceeding the category average by 1.68 points. Speech understanding in noisy environments scored 2.3/5, which is above the category average of 1.48 but represents mixed performance in absolute terms—meaning challenging noise situations may still prove difficult. The device offers flexible power options with both rechargeable and disposable batteries, and supports streaming from both iPhone and Android devices with hands-free capability. Feedback handling is excellent at 4.5/5, essentially matching the category average, while own-voice comfort scores a solid 3.0/5. The Audicus Omni 2 is best suited for consumers seeking a premium OTC option with strong everyday speech clarity and quality streaming capabilities.

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.
