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.

Zepp Clarity Pixie
The Zepp Clarity Pixie is a mid-priced OTC hearing aid featuring an invisible-in-ear design, priced at $999. In our lab testing, it earned a B grade with a SoundScore of 3.6/5, placing it in the top 48% of OTC hearing aids tested. Speech clarity is a notable strength for the Pixie. It scores 3.6/5 for speech in quiet—a solid result that sits 0.77 points above the category average. Speech in noise performance is above the category average as well, though at 1.7/5 it remains low in absolute terms. Feedback handling is strong at 4.3/5, though slightly below the category average of 4.54/5. The Pixie shows significant limitations in other areas. Own-voice comfort scores just 1.5/5, falling 1.01 points below the category average—users may notice their own voice sounds unnatural or boomy. Music streaming is a particular weakness, scoring 0.0/5, which is 1.92 points below the category average. Those who frequently stream phone audio should consider alternatives. At this price point, competitors offer stronger overall performance. The Yeasound RIC800 and Sony CRE-E10 both score above 4.6/5 at similar prices. The Elehear Delight and Yeasound RIC700 deliver scores around 4.3/5 at lower price points. The Pixie may appeal to users who prioritize its discreet invisible-in-ear form factor and primarily need speech clarity in quieter environments, but those seeking well-rounded performance or music streaming should explore alternatives.
