Linner Mars vs Orka Two
Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

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.
Choice

Orka Two
The Orka Two is a behind-the-ear prescription hearing aid priced at $1,899, earning an A grade with a SoundScore of 4.0/5 in our lab testing. It ranks #27 of 39 devices in the Prescription Hearing Aid category, placing it in the top 67% of its class. In our testing, the Orka Two demonstrates notable strengths in several areas. Speech in quiet environments scores a solid 3.7/5, measuring 0.32 points above the category average. Music streaming quality also performs well at 3.3/5, sitting 0.54 points above average—a plus for users who frequently stream audio from their phones. Own-voice comfort scores 3.2/5, which is 0.50 points above the category norm, and feedback handling is excellent at a perfect 5.0/5. The device's most significant limitation is speech understanding in noisy environments, where it scores 1.4/5—a low result that falls 0.71 points below the category average. This weakness may impact users who frequently encounter challenging listening situations like busy restaurants or social gatherings. The Orka Two includes Bluetooth streaming for both iPhone and Android devices, hands-free calling capability, and rechargeable batteries. While it delivers solid overall performance for its price tier, shoppers comparing options in this range should note that some competitors like the Rexton Reach R-Li T80 at Costco achieve higher overall scores. The Orka Two is best suited for users who prioritize quiet conversation clarity, streaming quality, and comfort, and who encounter noisy environments less frequently.
