Choice

Eargo Link
The Eargo Link is a mid-priced OTC hearing aid released in 2024, earning an A grade with a SoundScore of 4.1/5 in our lab testing. At $799, it ranks #15 of 65 OTC hearing aids tested, placing it in the top 22% of the category. In our testing, the Eargo Link demonstrates notable strengths in music streaming, scoring 4.4/5—a strong result that sits 2.48 points above the category average. This makes it a standout choice for users who prioritize audio quality when streaming from their phone. Speech performance is solid, with speech in quiet measuring 3.2/5 (0.42 points above average) and speech in noise at 2.0/5 (0.54 points above average, though mixed in absolute terms). Feedback handling is excellent at 4.7/5. The main limitation is own-voice comfort, which scores 1.3/5—a low result that falls 1.21 points below the category average. Users sensitive to the sound of their own voice may find this challenging, particularly with the closed dome configuration used in the tuned fit. The Eargo Link supports both iPhone and Android streaming with hands-free capability and uses rechargeable batteries. It's best suited for those who value exceptional music streaming quality and solid speech clarity, and who can tolerate some own-voice occlusion. Competitors in this price range include higher-scoring options like the Yeasound RIC800 and Sony CRE-E10, though the Eargo Link's streaming performance remains a differentiator.

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.
