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

EarCentric EasyCharge
The EarCentric EasyCharge is a budget-priced prescription hearing aid available for $229, earning a C grade with a SoundScore of 2.7/5 in our lab testing. This behind-the-ear rechargeable device ranks #36 of 39 prescription hearing aids tested, placing it in the bottom tier of its category. In our standardized testing, the EasyCharge demonstrates a stark performance divide. Its standout strength is feedback handling, scoring an excellent 5.0/5—slightly above the category average of 4.72. This means users can expect stable performance without whistling during typical daily activities. However, speech clarity metrics tell a different story: speech in quiet scores just 1.0/5, which is 2.40 points below the category average, and speech in noise also scores 1.0/5, falling 1.11 points below average. Music streaming scored 0.0/5, indicating this device is not suitable for audio enjoyment. Own-voice comfort is also limited at 1.9/5, which is 0.80 points below the prescription hearing aid average of 2.70. The device showed no improvement between initial and tuned fitting conditions, with both scoring 2.7/5. At this price point, shoppers should note that alternatives exist with meaningfully better performance. The RxEars Rxi, available in the same price range, scores 4.07/5. The EasyCharge may appeal to those prioritizing feedback-free operation on a tight budget, but its low speech clarity scores suggest significant limitations for everyday conversation.

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.
