The Eargo 7 is a premium-priced OTC hearing aid at $2,550, featuring an invisible-in-ear design with rechargeable batteries. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.5/5, placing it in the top 57% of the OTC hearing aid category. Speech performance in quiet environments is a strength for the Eargo 7, scoring 3.1/5—0.33 points above the category average. Own-voice comfort also exceeds the category average by 0.39 points, though at 2.9/5 it remains mixed in absolute terms. However, speech understanding in noisy environments presents a limitation, scoring 1.0/5, which falls 0.44 points below the category average. A significant drawback is the complete absence of music streaming capability, scoring 0.0/5—nearly 2 points below the category average. Feedback handling is solid at 3.8/5 in absolute terms, though it falls 0.74 points below the category average for OTC devices. The Eargo 7 may appeal to users who prioritize a discreet, nearly invisible form factor and primarily need assistance in quieter listening situations. However, consumers seeking strong noise performance or music streaming should be aware of these limitations, particularly given the premium price point. Several alternatives at lower price points achieve higher overall scores in our testing.

The Phonak Audéo EON Sphere is a premium behind-the-ear prescription hearing aid priced at $4,398. In HearAdvisor's lab testing, it earned a SoundScore of 5.0/5 and an A grade, placing it among the top performers in the prescription hearing aid category. Speech performance stands out as this device's greatest strength. Speech in noise scored an excellent 4.5/5, a full 2.53 points above the category average of 1.96/5—a substantial margin that makes this one of the strongest performers in challenging listening environments. Speech in quiet also performed well at 4.3/5, nearly a full point above the category average. These results suggest the Audéo EON Sphere may be particularly well-suited for users who frequently encounter noisy social settings or group conversations. Music streaming delivered a solid 3.7/5, more than a point above the category average of 2.64/5, indicating above-average audio fidelity for phone-streamed content. Own-voice comfort scored 2.8/5, which sits just above the category average but reflects mixed absolute performance—users sensitive to occlusion effects should discuss this with their hearing care provider. Feedback handling scored an excellent 4.6/5 in absolute terms, though it lands slightly below the category average of 4.71/5. The Audéo EON Sphere represents Phonak's latest premium technology and delivers strong results across most metrics in our standardized testing. It's best suited for users prioritizing speech clarity in difficult listening situations who are prepared for the premium price point.
