EargoSoundScore 4.1Grade A

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.

OticonSoundScore 4.7Grade A

Oticon Zeal

The Oticon Zeal is a premium prescription hearing aid in the invisible-in-ear style, carrying an A grade with a SoundScore of 4.7/5 in our lab testing. Priced at $4,798, it ranks #6 among 39 prescription hearing aids tested, placing it in the top 13% of its category. Speech performance is where the Zeal truly excels. Our testing measured an excellent 4.9/5 for speech in quiet—1.48 points above the category average—making it one of the strongest performers for everyday conversations. Speech in noise also scores a solid 3.0/5, sitting 0.93 points above the category average of 2.11/5, indicating reliable performance in moderately challenging listening environments. Music streaming quality registers at a solid 3.3/5, which is 0.54 points above the category average. However, the Zeal shows some limitations in other areas. Own-voice comfort scores a mixed 2.0/5, falling 0.70 points below the category average—something to consider if own-voice naturalness is a priority. Feedback handling measures at 3.3/5, which is solid in absolute terms but sits 1.42 points below the category average of 4.72/5. The Oticon Zeal is best suited for wearers who prioritize exceptional speech clarity and want a discreet, invisible-in-ear form factor. Those especially sensitive to feedback or own-voice effects may want to discuss these trade-offs with their hearing care provider during fitting.
