Jabra Enhance Select M3
The Jabra Enhance Select M3 is a premium OTC hearing aid priced at $1,995, earning an A grade with a SoundScore of 4.0/5 in our lab testing. This behind-the-ear device delivers strong overall performance, positioning it among the better-performing options in the OTC category. In our testing, the Enhance Select M3 showed notable strengths in speech clarity during quiet environments, scoring 3.8/5—a solid result that sits 0.95 points above the OTC category average. Music streaming quality also performs well at 2.8/5, which is 0.87 points above average for the category, though still mixed in absolute terms. Feedback handling is excellent at 4.6/5, ensuring stable performance during movement and daily activities. The device does show limitations in challenging listening environments. Speech in noise scored 1.3/5, which falls 0.18 points below the category average and represents a low absolute score. Users who frequently encounter noisy restaurants, busy social gatherings, or similar environments may find this a meaningful limitation. Own-voice comfort scored 2.7/5—above the category average by 0.18 points but only mixed in absolute terms. Consumers seeking strong performance in quieter settings with good music streaming capability may find the Enhance Select M3 appealing. However, shoppers should note that alternatives like the Sennheiser All Day Clear and Jabra Enhance Pro 20 at Costco offer comparable or higher scores at lower price points, potentially representing better overall value for budget-conscious buyers.

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.
