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.

iBstone AuraLink
The iBstone AuraLink is a mid-priced OTC hearing aid released in 2024, earning a B grade with a SoundScore of 3.6/5 in our lab testing. At $649, it ranks #33 of 65 OTC hearing aids tested, placing it in the top 49% of its category. This behind-the-ear device demonstrates a distinctive performance profile with notable strengths in specific areas. Music streaming stands out as a clear highlight, scoring 3.6/5—a solid result that lands 1.68 points above the OTC category average. Feedback handling is excellent at 5.0/5, exceeding the already-high category average by 0.46 points. Own-voice comfort scores 2.7/5, slightly above the category average but only mixed in absolute terms. The AuraLink's limitations appear in speech clarity metrics. Speech in quiet scores 2.3/5, falling 0.47 points below the category average—a mixed result that may affect conversational understanding in calm environments. Speech in noise presents a more significant challenge at 1.0/5, which is 0.48 points below the category average and low in absolute terms. This hearing aid may appeal most to users who prioritize music listening and phone streaming over speech clarity in challenging environments. However, budget-conscious shoppers should note that alternatives like the iHear MatriX offer higher scores at lower prices. The AuraLink's strength in feedback stability and streaming audio quality represents a specific value proposition for users whose priorities align with these capabilities.
