Apple AirPods Pro 2
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.

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.
