Choice

Eargo Link
The Eargo Link is a mid-priced OTC hearing aid that earned an A grade with a SoundScore of 4.1/5 in our lab testing, placing it in the top 22% of the OTC hearing aid category. At $799, this visible-in-ear style device offers a balance of solid speech performance and exceptional streaming capabilities. In our testing, the Eargo Link demonstrated strong music streaming quality, scoring 2.48 points above the category average—a standout result for consumers who prioritize audio entertainment. Speech in quiet environments also performed well at 0.42 points above average, while speech in noise scored above the category average but remained mixed in absolute terms at 2.0/5. Feedback handling was excellent at 4.7/5. The most notable limitation is own-voice comfort, which scored 1.3/5—significantly below the category average by 1.21 points. Users sensitive to hearing their own voice may find this distracting, particularly with the closed dome configuration used in our tuned fit. The Eargo Link features rechargeable batteries and supports both iPhone and Android streaming with hands-free functionality. It's best suited for consumers who value premium streaming audio quality and solid speech clarity in quieter settings, and who can tolerate some own-voice compromise. Those prioritizing speech in noise or own-voice comfort may want to consider alternatives like the Sony CRE-E10 or Lexie B2 Plus in this price range.

Linner Mars
The Linner Mars is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.1/5 in our lab testing. At $399, it falls in the lowest price tier for OTC devices, though its overall sound performance ranks #55 of 65 in the OTC Hearing Aid category. This device presents a stark contrast in performance across different listening situations. Music streaming is a genuine standout, scoring an excellent 4.6/5—well above the category average. Feedback handling also earns a perfect 5.0/5, meaning users shouldn't experience whistling or squealing issues. However, the Mars struggles significantly with its core hearing aid function: speech clarity. Speech in quiet scores just 1.9/5, and speech in noise drops to 1.0/5, both falling below category averages. Own-voice comfort is another weak point at 1.0/5, which is 1.51 points below the category average. Users may find their own voice sounds unnatural or boomy when wearing these devices. The tuned fit shows modest improvement over the initial fit (3.4/5 vs 3.1/5), primarily through better speech-in-quiet performance. The Linner Mars may appeal to budget-conscious consumers who prioritize music and media streaming over speech understanding. However, several competitors in the same price range—including the Elehear Beyond and Apple AirPods Pro 2—offer substantially better overall sound performance. Those seeking improved speech clarity should consider alternatives that score higher in that critical area.
