JVC EH-Z1500
The JVC EH-Z1500 is a mid-priced OTC hearing aid available at $600, earning an A grade with a SoundScore of 4.0/5 in our lab testing. This behind-the-ear device ranks #19 among 65 OTC hearing aids tested, placing it in the top 28% of the category. Speech clarity is where this device truly excels. The EH-Z1500 delivers excellent speech-in-quiet performance at 4.6/5, scoring 1.77 points above the category average. Speech-in-noise performance is above the category average by 1.09 points, though at 2.6/5 it remains mixed in absolute terms—adequate for moderately challenging environments but not exceptional. Key limitations include music streaming, which scores 0.0/5—well below the category average of 1.92/5. Users who prioritize audio streaming from phones should look elsewhere. Feedback handling is solid at 3.8/5, though this falls 0.74 points below the category average of 4.54/5. Own-voice comfort scores 2.4/5, roughly in line with category norms. The EH-Z1500 uses disposable batteries rather than rechargeables. Competitors in this price range include higher-scoring options like the Yeasound RIC800 (4.76/5) and Sony CRE-E10 (4.69/5). This device is best suited for users who prioritize speech understanding in everyday conversations and don't require music streaming capabilities.

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.
