JLab Hear OTC

The JLab Hear OTC is a budget-friendly OTC hearing aid priced at $100, earning a B grade with a SoundScore of 3.6/5 in HearAdvisor's lab testing. This visible-in-ear device ranks #36 of 65 OTC hearing aids tested, placing it in the top 54% of its category. In our testing, the JLab Hear OTC shows a distinctive performance profile with clear strengths and weaknesses. Music streaming stands out as exceptional, scoring 4.6/5—a remarkable 2.68 points above the category average. Feedback handling also performs excellently at 5.0/5, providing stable amplification without whistling during our standardized challenge motions. These strengths make it particularly well-suited for users who prioritize streaming audio content. However, speech performance presents limitations. Speech in quiet scores 2.1/5, which is 0.67 points below the category average of 2.79. Speech in noise is more constrained at 1.0/5, falling 0.46 points below average. Own-voice comfort also scores low at 1.8/5, which is 0.71 points below the category norm. These results suggest the device may be less effective for primary speech amplification needs compared to alternatives in its price range. The JLab Hear OTC includes rechargeable batteries and supports both iPhone and Android streaming with hands-free functionality. At this price point, competitors like the Elehear Beyond (4.36/5) and Apple AirPods Pro 2 (4.06/5) offer stronger overall sound performance. This device may appeal most to budget-conscious users who value excellent streaming quality and feedback stability over speech enhancement capabilities.

Linner Mars Hero
LinnerSoundGrade B

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.
