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

Go Hearing Go Prime
The Go Hearing Go Prime is a budget OTC hearing aid priced at $299, earning a B grade with a SoundScore of 3.3/5 in HearAdvisor's lab testing. This visible-in-ear style device ranks #50 of 65 OTC hearing aids tested, placing it in the top 75% of its category. In our testing, the Go Prime demonstrated excellent feedback handling, scoring a perfect 5.0/5—notably 0.46 points above the category average. This means users can expect stable performance without the whistling that can plague some hearing aids. Speech clarity in quiet environments measured at a mixed 2.7/5, slightly below the category average. Speech understanding in noisy situations scored low at 1.1/5, falling 0.39 points below average, suggesting this device may struggle in challenging listening environments like restaurants or social gatherings. The Go Prime's most significant limitation is its music streaming capability, which scored 0.0/5—nearly 2 points below the category average. Users who prioritize phone-streamed audio should consider alternatives. Own-voice comfort also scored low at 1.8/5, which may result in a "boomy" quality when speaking. At this price point, several competitors offer stronger overall performance, including the Elehear Beyond and Apple AirPods Pro 2. However, for budget-conscious consumers who primarily need basic amplification in quieter settings and value feedback-free operation, the Go Prime offers a functional entry point. The rechargeable batteries add convenience for daily use.

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.
