Linner Mars vs Lucid Enrich Pro
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.

Lucid Enrich Pro
The Lucid Enrich Pro is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.7/5 in our lab testing. At $200, it ranks #31 of 65 OTC hearing aids tested, placing it in the top 46% of the category. This visible-in-ear device delivers its strongest performance in speech-in-quiet scenarios, scoring 3.8/5—a solid result that sits 0.98 points above the OTC category average. Feedback handling is also strong at 4.0/5 in absolute terms, though it falls 0.54 points below the category average. Speech-in-noise performance scores 1.7/5, which is above the category average by 0.19 points but remains low in absolute terms, suggesting limited benefit in challenging listening environments. Key limitations include own-voice comfort, which scores a mixed 2.0/5 (0.51 points below category average), and music streaming, which scores 0.0/5—significantly below the category average of 1.92/5. The device uses disposable batteries rather than rechargeables. The Lucid Enrich Pro may suit budget-conscious consumers who primarily need help hearing speech in quieter settings and don't require music streaming functionality. Those who frequently encounter noisy environments or value streaming audio should consider alternatives in this price range, such as the higher-scoring Elehear Beyond or Apple AirPods Pro 2.
