Choice

Elehear Beyond Pro
The Elehear Beyond Pro is a mid-priced OTC hearing aid that earns an A grade with a SoundScore of 4.2/5 in our lab testing, placing it #11 out of 65 OTC devices tested. At $631, this behind-the-ear rechargeable device delivers strong overall performance and has earned HearAdvisor's Expert's Choice Award for both 2024 and 2025. In our testing, the Beyond Pro excels in music streaming, scoring 3.8/5—a solid result that sits 1.88 points above the OTC category average of 1.92/5. Speech clarity in quiet environments also performs well at 3.3/5, which is 0.46 points above average. Speech in noise scores 2.5/5, which is above the category average by 1.00 points, though this remains a mixed result in absolute terms. Feedback handling is excellent at a perfect 5.0/5. The primary limitation is own-voice comfort, which scores 1.2/5—a low result that falls 1.31 points below the category average. Users sensitive to hearing their own voice may find this more noticeable. The device uses closed domes with a medium-power receiver and achieved identical scores in both initial and tuned fit conditions in our testing. The Beyond Pro supports both iPhone and Android streaming with hands-free functionality. It's best suited for users who prioritize streaming audio quality and speech clarity and are less sensitive to own-voice occlusion effects. Within its price range, it competes with devices like the Sony CRE-E10 and Lexie B2 Plus, though some competitors in this tier score higher overall.

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.
