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.

Zepp Clarity One
The Zepp Clarity One is a mid-priced OTC hearing aid with an invisible-in-ear design, priced at $699. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.9/5, ranking #23 among 65 OTC hearing aids tested—placing it in the top 34% of its category. This device demonstrates notable strengths in specific areas of sound performance. Speech clarity in quiet environments scores a solid 3.7/5, coming in 0.95 points above the category average. Own-voice comfort is another highlight at 3.8/5, exceeding the category average by 1.29 points—a meaningful advantage for users sensitive to how their own voice sounds while wearing hearing aids. Feedback handling is excellent at 5.0/5, among the best we've measured. However, the Zepp Clarity One shows limitations in other areas. Speech understanding in noisy environments scores 1.4/5, slightly below the category average and low in absolute terms. Music streaming capability is notably absent, scoring 0.0/5—well below the already modest category average of 1.92/5. Users who prioritize phone audio streaming should consider this significant limitation. The Zepp Clarity One may suit consumers who primarily need hearing support in quieter settings like one-on-one conversations at home, and who value discreet, in-ear styling with reliable feedback control. Those frequently navigating noisy environments or wanting to stream music and calls should explore alternatives.
