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 released in 2023, earning a B grade with a SoundScore of 3.2/5 in our lab testing. At $399, it falls in the lower price tier of the OTC category but ranks #55 of 65 OTC devices tested, placing it in the bottom 17% of its category. This visible-in-ear device presents a mixed performance profile with notable strengths and significant weaknesses. Music streaming is a standout feature, scoring an excellent 4.6/5—a full 2.68 points above the category average. Feedback handling is also excellent at 5.0/5, meaning users can expect stable performance without whistling during normal use. However, speech clarity presents challenges. Speech in quiet scores a low 1.9/5, falling 0.85 points below the category average. Speech in noise performance is particularly limited at 1.0/5, sitting 0.46 points below average. Own-voice comfort also scores low at 1.0/5, which is 1.51 points below the category average—users may notice their own voice sounding unnatural or boomy. The Linner Mars may suit budget-conscious consumers who prioritize music and media streaming over speech understanding in challenging environments. However, buyers seeking better speech performance should consider alternatives like the Elehear Beyond or Apple AirPods Pro 2, which offer stronger overall sound scores in the same price range.

In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.8/5, placing it in the top 8% of all prescription hearing aids tested and ranking #4 out of 36 devices in its category. Speech performance is a standout strength.

While the speech-in-noise result is above average for the category, it remains mixed in absolute terms at 2.9/5 after tuning, reflecting the inherent challenge of noisy environments for all hearing aids. Music streaming quality starts strong at 4.2/5 on initial fit, though it drops to a mixed 2.8/5 after tuning—still slightly above the category average. Feedback handling scores a solid 4.0/5, which is strong in absolute terms, though it falls 0.71 points below the category average of 4.71/5.
