Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Eargo 7
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.
Choice

Signia Styletto C&G IX
The Signia Styletto C&G IX is a premium prescription behind-the-ear hearing aid released in 2024, priced at $3,398. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.6/5, placing it in the top 25% of prescription hearing aids and ranking #10 of 36 devices in its category. This device demonstrates strong performance across most sound quality metrics in our testing. Speech in quiet scored 3.9/5, which is 0.62 points above the category average of 3.32/5. Speech in noise came in at 2.5/5—above the category average by 0.58 points, though only mixed in absolute terms. Own-voice comfort was a particular strength at 3.7/5, exceeding the category average by 0.95 points. Music streaming quality scored a solid 3.1/5, sitting 0.46 points above the category average. However, feedback handling measured 3.6/5, which while solid in absolute terms, falls 1.11 points below the category average of 4.71/5. This represents the device's primary weakness relative to competitors. The Styletto C&G IX features rechargeable batteries, iPhone and Android streaming, and hands-free calling capability. It has earned HearAdvisor's Expert's Choice Award in both 2023 and 2024. Consumers seeking similar sound performance at lower prices may want to compare the Rexton Reach R-Li T80 at Costco or the Lexie B2 Plus. This device is best suited for those prioritizing speech clarity and own-voice comfort who can accept slightly below-average feedback performance.
