Eargo Link Hero
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.

Sontro Soundwave Hero
SontroSoundScore 3.0Grade B

Sontro Soundwave

The Sontro Soundwave is a mid-priced OTC hearing aid that earns a B grade with a SoundScore of 3.0/5 in our lab testing. At $849, this behind-the-ear device uses disposable batteries and sits in the lower tier of OTC performance, ranking #61 of 65 devices in its category. The Soundwave's strongest attribute is own-voice comfort, scoring 3.6/5—a solid result that sits 1.09 points above the OTC category average. This makes it relatively comfortable for wearers who are sensitive to hearing their own voice sound unnatural or boomy. However, other performance areas present significant limitations. Speech clarity scores are below average in both quiet and noisy environments. Speech in quiet scores 2.7/5 (0.12 points below average), while speech in noise drops to 1.2/5 (0.28 points below average). Feedback handling is a notable weakness at 2.5/5, falling 2.04 points below the category average of 4.54/5. Perhaps most limiting is the music streaming score of 0.0/5, indicating this device does not support phone audio streaming—a feature many competitors in this price range offer. Consumers prioritizing own-voice comfort on a moderate budget may find the Soundwave acceptable, but those seeking strong speech clarity or streaming capability should consider alternatives. Several higher-performing OTC devices are available at similar or lower price points, including options like the Lexie Lumen or HearingAssist Control that deliver comparable or better overall sound quality.
