Linner Mars vs Oticon Real
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
Oticon Real
The Oticon Real is a premium prescription behind-the-ear hearing aid released in 2023, priced at $4,798. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.7/5, placing it in the top 10% of the 39 prescription hearing aids tested and ranking #5 in its category. Speech performance is a clear strength for the Oticon Real. Speech in quiet scored a strong 4.0/5, sitting 0.64 points above the category average. Speech in noise measured 2.9/5—above the category average by 0.82 points, though still mixed in absolute terms. This combination makes it a solid choice for listeners prioritizing conversation clarity across different environments. Feedback handling scored a strong 4.0/5 in absolute terms, though this falls 0.72 points below the category average of 4.72/5. Own voice comfort scored 2.4/5, which is 0.30 points below the category average—a potential consideration for those sensitive to how their own voice sounds. Music streaming performance was mixed at 2.8/5, essentially matching the category average. The Oticon Real is a two-time Expert's Choice Award winner (2023, 2024) and offers flexible power options with both rechargeable and disposable batteries. It supports iPhone and Android streaming along with hands-free calling. Within its premium price tier, it faces strong competition from devices like the Phonak Sphere Infinio and Oticon Intent, but remains a compelling option for users who prioritize speech intelligibility and are willing to invest in top-tier technology.
