Apple AirPods Pro 3 vs Linner Mercury
Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Apple AirPods Pro 3
The Apple AirPods Pro 3 is a budget-priced OTC hearing aid available at $250, earning a B grade with a SoundScore of 3.3/5 in our lab testing. This visible-in-ear device ranks #49 of 65 OTC hearing aids tested, placing it in the top 74% of its category. The standout performance area is music streaming, scoring a strong 4.3/5—a full 2.38 points above the category average. Feedback handling is excellent at 5.0/5, meaning users can expect stable performance without whistling during normal use. However, speech performance presents a more mixed picture: speech in quiet scores 2.3/5, falling 0.53 points below the category average, while speech in noise scores 1.8/5—above the category average but low in absolute terms. Own-voice comfort is a notable weakness at 1.9/5, scoring 0.61 points below the category average, which may affect how natural your own speech sounds while wearing the devices. The product showed meaningful improvement from tuning, with the normalized score rising from 3.2/5 to 3.8/5 after adjustment. The AirPods Pro 3 is best suited for users who prioritize music streaming quality and seamless Apple ecosystem integration over maximum speech clarity. Budget-conscious shoppers should note that several competitors in the same price range—including the Elehear Beyond and the previous-generation Apple AirPods Pro 2—achieved higher overall scores in our testing.

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.
