Apple AirPods Pro 2 vs Linner Mars

The Apple AirPods Pro 2 is a budget-priced OTC hearing aid that earned an A grade with a SoundScore of 4.0/5 in our lab testing, ranking #18 among 65 OTC hearing aids tested. At $249, it offers hearing assistance through Apple's familiar true-wireless earbud design. In our testing, the AirPods Pro 2 demonstrated strong performance in speech clarity during quiet listening situations, scoring 4.2/5—a full 1.38 points above the OTC category average. Music streaming quality is a standout strength at 4.4/5, exceeding the category average by 2.48 points and delivering strong linear fidelity for phone audio. Feedback handling earned a perfect 5.0/5, indicating excellent stability during movement. Speech understanding in noisy environments scored 2.3/5, which is above the category average by 0.77 points but remains mixed in absolute terms—users in challenging acoustic situations may find performance adequate rather than exceptional. Own-voice comfort is a limitation, scoring 1.9/5 and falling 0.61 points below the category average, which may result in noticeable occlusion effects when speaking. The AirPods Pro 2 is best suited for iPhone users seeking a discreet, multipurpose device that combines solid speech clarity in quieter settings with excellent music streaming. Those who prioritize own-voice naturalness or need stronger noise performance may want to explore alternatives.

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.
