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.
Choice

Phonak Sphere Infinio
The Phonak Sphere Infinio is a premium behind-the-ear prescription hearing aid released in 2024, priced at $4,898. In our lab testing, it earned an A grade with a SoundScore of 5.0/5, placing it at #2 among 39 prescription hearing aids tested—within the top 3% of its category. The standout performance comes in speech clarity. Speech in noise scores an excellent 4.7/5, a remarkable 2.59 points above the category average of 2.11/5. Speech in quiet also impresses at 4.5/5, sitting 1.07 points above average. For anyone who struggles to follow conversations in restaurants, gatherings, or busy environments, this device delivers measurably superior intelligibility compared to most alternatives we've tested. Music streaming quality is strong at 4.0/5, exceeding the category average by 1.24 points—a meaningful advantage for users who value audio fidelity when streaming from phones. However, own-voice comfort is mixed at 2.3/5, falling 0.40 points below the category average, which may affect how natural your own speech sounds. Feedback handling, while solid in absolute terms at 3.6/5, sits 1.12 points below the category average of 4.72/5. The Sphere Infinio is best suited for users prioritizing exceptional speech understanding, particularly in challenging noise environments, and who are willing to invest at the premium tier. Those especially sensitive to own-voice quality or requiring maximum feedback stability may want to compare alternatives like the similarly-priced Oticon Intent or the lower-priced Phonak Audéo EON Sphere.
