Eargo 8
The Eargo 8 is a premium-priced OTC hearing aid featuring an invisible-in-ear design with rechargeable batteries, priced at $2,399. In our lab testing, it earned a B grade with a SoundScore of 3.4/5, placing it in the top 71% of the OTC Hearing Aid category. Sound performance presents a mixed picture. The Eargo 8 delivers solid speech-in-quiet performance at 3.1/5, scoring 0.27 points above the category average—making it a reasonable choice for conversational settings without background noise. Own-voice comfort is another strength, measuring 0.69 points above average at 3.2/5, which may appeal to users who are sensitive to hearing their own voice through hearing aids. Feedback handling is strong in absolute terms at 4.2/5, though slightly below the category average. However, the device shows notable weaknesses in challenging listening environments. Speech-in-noise performance is low at 1.2/5, falling 0.27 points below the category average—users who frequently encounter noisy restaurants, busy offices, or social gatherings may find this limiting. Music streaming scored 0.0/5, significantly below the category average, making this device unsuitable for users who prioritize audio entertainment through their hearing aids. The Eargo 8 is best suited for users who prioritize discreet, invisible-in-ear styling and primarily need assistance in quieter conversational settings. However, at this premium price point, buyers should be aware that similarly-priced alternatives and even some lower-cost options may offer comparable or better overall sound performance.

Signia Pure C&G BCT IX
The Signia Pure C&G BCT IX is a premium prescription behind-the-ear hearing aid released in 2025, priced at $3,398. In our lab testing, it earned an A grade with a SoundScore of 4.4/5, placing it in the top 39% of the 36 prescription hearing aids we've tested. This device shows notable strengths in speech clarity and own-voice comfort. Speech in quiet scored 3.8/5, which is 0.47 points above the category average—a solid result for everyday conversations. Speech in noise measured 2.5/5, above the category average by 0.58 points, though only mixed in absolute terms, meaning challenging listening environments may still present difficulty. Own-voice comfort is a standout at 3.8/5, a full 1.05 points above average, suggesting reduced occlusion effects that many wearers find bothersome. Feedback handling scored 4.2/5—strong in absolute terms, though 0.51 points below the category average of 4.71/5. Music streaming at 2.7/5 is essentially on par with category average. The device features rechargeable batteries, iPhone and Android streaming, and hands-free functionality. Consumers shopping in this premium price tier should note that several alternatives offer higher overall scores, including the Phonak Sphere Infinio (5.0/5) and Oticon Intent (4.85/5). For those prioritizing own-voice comfort and solid speech performance in quieter settings, the Pure C&G BCT IX delivers, but buyers seeking top-tier noise performance may want to compare options.
