Linner Mars vs Signia Active Mini IX
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.

Signia Active Mini IX
The Signia Active Mini IX is a premium prescription hearing aid with a visible-in-ear design, priced at $4,696. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.5/5, ranking #14 of 39 prescription hearing aids tested—placing it in the top 33% of its category. This device demonstrates strong speech clarity performance in our testing. Speech in quiet scored 4.1/5, which is +0.71 points above the category average of 3.40/5. Speech in noise measured 2.6/5—above the category average by +0.46 points, though only mixed in absolute terms at 2.6/5. Music streaming is a notable strength at 3.6/5, outperforming the category average by +0.84 points. Own-voice comfort scored a solid 3.2/5, sitting +0.50 points above average. However, feedback handling represents a limitation for this device, scoring 2.5/5—a mixed result that falls -2.22 points below the category average of 4.72/5. Users sensitive to feedback may want to discuss this with their hearing care provider. The Signia Active Mini IX delivers excellent overall sound performance with particular strengths in speech clarity and streaming audio quality. It's best suited for users who prioritize these capabilities and can work with their provider to manage the feedback handling limitations. The earbud-style design offers a modern, discreet appearance for those who prefer visible-in-ear devices.
