Jabra Enhance Plus vs MDHearing VoltMax
Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Jabra Enhance Plus
The Jabra Enhance Plus is a mid-priced OTC hearing aid ($799) that earns a B grade with a SoundScore of 3.8/5 in our lab testing, ranking #28 of 65 devices in the OTC category. This visible-in-ear device delivers strong speech-in-quiet performance, scoring 4.2/5—a full 1.36 points above the category average. Music streaming is another highlight at 3.8/5, nearly 1.9 points above average, making it a solid choice for users who value audio quality beyond speech. Speech-in-noise performance scores 2.1/5, which is above the category average by 0.62 points but remains mixed in absolute terms for challenging listening environments. The most significant limitation is own-voice comfort, scoring just 0.3/5—well below the category average of 2.51/5. Users sensitive to how their own voice sounds while wearing hearing aids should consider this trade-off carefully. Feedback handling is excellent at 4.7/5, meaning wearers can expect stable performance without whistling or squealing. The Jabra Enhance Plus is best suited for users who prioritize clear speech in quieter settings and enjoy streaming music or calls to their iPhone. Those frequently in noisy environments or particularly bothered by occlusion effects may want to explore alternatives. Several competitors in the same price range achieve higher overall scores, including the Sony CRE-E10 and Lexie B2 Plus.

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.
