Eargo 6 vs Starkey Evolv AI
Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Eargo 6
The Eargo 6 is a premium-priced OTC hearing aid ($2,250) that earned a B grade and a SoundScore of 3.4/5 in our lab testing, placing it in the top 63% of OTC hearing aids we've evaluated. This invisible-in-ear device delivers solid speech clarity in quiet environments, scoring 3.3/5—notably 0.53 points above the OTC category average. Own-voice comfort is also above average at 2.9/5, though mixed in absolute terms. However, the Eargo 6 shows significant weaknesses in challenging listening situations, with speech-in-noise performance scoring just 1.0/5, falling 0.48 points below the category average. The most notable limitation is music streaming, which scored 0.0/5 in our testing—substantially below the category average. Feedback handling scored 3.3/5, solid in absolute terms but 1.24 points below the OTC average of 4.54/5. The device uses rechargeable batteries and maintains a fully invisible profile when worn. The Eargo 6 may suit consumers who prioritize discreet aesthetics and primarily need help hearing conversations in quieter settings. However, shoppers should note that alternatives like the Sony CRE-C10 and Olive Union Air achieved higher SoundScores at lower price points. Those frequently in noisy environments or who value music streaming should explore other options.

Starkey Evolv AI
The Starkey Evolv AI is a premium behind-the-ear prescription hearing aid released in 2022, currently available at $4,598. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.9/5, ranking #28 of 36 prescription hearing aids tested. This device shows notable strengths in specific performance areas. Music streaming quality stands out at 3.7/5, scoring 1.06 points above the category average—making it a solid choice for users who prioritize audio entertainment. Speech in noise performance reaches 2.8/5, which is 0.81 points above the category average, though the absolute score reflects mixed real-world performance in challenging listening environments. Speech in quiet is solid at 3.4/5, slightly above average. The Evolv AI does show weaknesses in two key areas. Own voice comfort scores 2.1/5, falling 0.65 points below the category average, which may affect how natural your own speech sounds. Feedback handling, while solid in absolute terms at 3.5/5, runs 1.21 points below the category average of 4.71/5—meaning competitors in this price tier generally offer better feedback suppression. At this premium price point, several alternatives deliver stronger overall performance, including the Phonak Sphere Infinio and Oticon Intent. However, the Evolv AI's Expert's Choice Award recognition in 2023 and 2024 reflects its practical strengths. This hearing aid may suit users who prioritize music streaming quality and improved speech understanding in noise over own-voice comfort, and who value Starkey's feature set including rechargeable batteries and hands-free calling for both iPhone and Android.
