Eargo SE vs Phonak Sphere Infinio
Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Eargo SE
The Eargo SE is a premium-priced OTC hearing aid at $1,699, featuring an invisible-in-ear design and earning a B grade with a SoundScore of 3.1/5 in our lab testing. This places it in the top 85% of the OTC hearing aid category, ranking #56 of 65 devices tested. In our testing, the Eargo SE demonstrated solid performance in speech clarity for quiet environments, scoring 3.2/5—0.43 points above the category average. Feedback handling was excellent at 4.6/5, meaning users should experience stable performance without whistling issues. However, the device showed limitations in challenging listening situations, with speech in noise scoring 1.3/5, which falls 0.23 points below the category average. A notable weakness is the complete absence of music streaming capability, scoring 0.0/5 compared to the category average of 1.92/5. Own-voice comfort scored 2.4/5, slightly below the category average. These mixed results suggest the Eargo SE prioritizes its discreet form factor over comprehensive audio features. The Eargo SE may appeal to users who prioritize an invisible design and primarily need help hearing conversations in quieter settings. However, given its premium price point and the availability of alternatives like the Jabra Enhance Select 50R that deliver stronger overall scores at lower prices, value-conscious consumers may want to explore other options before committing.
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.
