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

Jabra Enhance Select 700
The Jabra Enhance Select 700 is a premium-priced OTC hearing aid available at $1,795, earning a B grade with a SoundScore of 3.8/5 in our lab testing. This behind-the-ear device ranks #26 of 65 OTC hearing aids tested, placing it in the top 38% of the category. In our testing, the Enhance Select 700 shows notable strengths in own-voice comfort, scoring 3.7/5—a solid result that sits 1.19 points above the category average. This makes it a comfortable choice for users sensitive to the "hollow" sound of their own voice that some hearing aids produce. Feedback handling is excellent at 5.0/5, meaning users can expect stable performance without whistling during typical daily activities. Speech clarity in quiet environments is solid at 3.1/5, coming in 0.27 points above the category average. However, speech understanding in noisy settings is a weakness, scoring just 1.0/5—falling 0.48 points below the category average. Users who frequently encounter restaurants, group gatherings, or other challenging listening environments may find this limitation significant. Music streaming quality is mixed at 2.5/5, though still 0.58 points above the category average. At this price point, buyers should note that several same-priced alternatives deliver stronger overall performance, including the Lucid Tala (4.63/5) and Audicus Omni 2 (4.61/5). The Enhance Select 700 is best suited for users who prioritize own-voice comfort and feedback-free wear over speech-in-noise performance, and who value Jabra's established brand and support ecosystem.

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.
