Apple AirPods Pro 3 vs Linner Mars
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 Mars
The Linner Mars is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.1/5 in our lab testing. At $399, it falls in the lowest price tier for OTC devices, though its overall sound performance ranks #55 of 65 in the OTC Hearing Aid category. This device presents a stark contrast in performance across different listening situations. Music streaming is a genuine standout, scoring an excellent 4.6/5—well above the category average. Feedback handling also earns a perfect 5.0/5, meaning users shouldn't experience whistling or squealing issues. However, the Mars struggles significantly with its core hearing aid function: speech clarity. Speech in quiet scores just 1.9/5, and speech in noise drops to 1.0/5, both falling below category averages. Own-voice comfort is another weak point at 1.0/5, which is 1.51 points below the category average. Users may find their own voice sounds unnatural or boomy when wearing these devices. The tuned fit shows modest improvement over the initial fit (3.4/5 vs 3.1/5), primarily through better speech-in-quiet performance. The Linner Mars may appeal to budget-conscious consumers who prioritize music and media streaming over speech understanding. However, several competitors in the same price range—including the Elehear Beyond and Apple AirPods Pro 2—offer substantially better overall sound performance. Those seeking improved speech clarity should consider alternatives that score higher in that critical area.
