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. This places it in the top 18% of the OTC hearing aid category, ranking #13 among 65 tested devices. In our testing, speech clarity in quiet environments stands out as a key strength, scoring 4.3/5—a strong result that measures 1.50 points above the category average. Feedback handling is excellent at 4.6/5, ensuring stable performance during everyday movements. Music streaming quality scores 2.9/5, which is 0.98 points above the category average but only mixed in absolute terms. The device shows some limitations worth noting. Speech understanding in noisy environments scores 1.8/5, which is above the category average by 0.31 points but low in absolute terms—a common challenge across OTC devices. Own-voice comfort scores 2.2/5, falling 0.31 points below the category average, which may be noticeable for users sensitive to how their own voice sounds. This two-time Expert's Choice Award winner (2023, 2024) offers rechargeable batteries and streaming compatibility with both iPhone and Android devices, including hands-free calling. Consumers seeking similar sound quality at a lower price point may want to compare the Jabra Enhance Select 300 or Lucid Engage. The Enhance Select 500 is best suited for those prioritizing strong speech clarity in quieter settings and reliable streaming performance within the premium OTC segment.

Linner Mercury
The Linner Mercury is a budget OTC hearing aid priced at $387, earning a B grade with a SoundScore of 3.0/5 in our lab testing. This visible-in-ear style device ranks #60 of 65 in the OTC Hearing Aid category, positioning it in the lower tier of available options. In our standardized testing, the Mercury demonstrates excellent feedback handling at 4.7/5, scoring 0.16 points above the category average. This means users are unlikely to experience whistling or squealing during typical wear. However, the device shows limitations in other key areas. Speech in quiet scores 2.2/5, falling 0.62 points below the category average, while speech in noise performance is low at 1.0/5, sitting 0.48 points below average. Own-voice comfort is also low at 1.6/5, measuring 0.91 points below the category average. The most significant limitation is music streaming, which scores 0.0/5—a full 1.92 points below the category average. Users who plan to stream phone calls or music through their hearing aids should consider alternatives. At this price point, competitors like the Elehear Beyond and Apple AirPods Pro 2 offer substantially higher overall scores. The Linner Mercury may suit budget-conscious first-time users who prioritize stable, feedback-free wear over streaming capabilities or challenging listening environments. However, those seeking better speech clarity or music quality should explore other options in this price range.
