Jabra Enhance Select 500
The Jabra Enhance Select 500 is a premium behind-the-ear OTC hearing aid priced at $1,995 that earns an A grade with a SoundScore of 4.2/5 in our lab testing. Ranking #13 of 65 OTC hearing aids tested, it places in the top 18% of its category. This 2024 release demonstrates strong speech-in-quiet performance, scoring 4.3/5—a full 1.50 points above the OTC category average. Speech-in-noise scores 1.8/5, which is above the category average by 0.31 points but remains low in absolute terms, reflecting a common challenge across OTC devices. Feedback handling is excellent at 4.6/5, slightly above the already-high category average. Music streaming scores 2.9/5, which is 0.98 points above the category average but only mixed in absolute terms—adequate for casual listening but not audiophile-quality. Own-voice comfort at 2.2/5 falls 0.31 points below the category average, which may be noticeable for users sensitive to how their voice sounds. The Enhance Select 500 supports iPhone and Android streaming, hands-free calling, and uses rechargeable batteries. It's a solid choice for those prioritizing clear speech in quieter environments and reliable feedback control. However, buyers seeking better value might consider the Jabra Enhance Select 300 or Lucid Engage, which offer similar sound performance at lower price points. This model has earned HearAdvisor's Expert's Choice Award in both 2023 and 2024.

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.
