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.

Starkey Evolv AI Hero
StarkeySoundGrade B

Starkey Evolv AI

The Starkey Evolv AI is a premium behind-the-ear prescription hearing aid released in 2022, currently available at $4,598. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.9/5, ranking #28 of 36 prescription hearing aids tested. This device shows notable strengths in specific performance areas. Music streaming quality stands out at 3.7/5, scoring 1.06 points above the category average—making it a solid choice for users who prioritize audio entertainment. Speech in noise performance reaches 2.8/5, which is 0.81 points above the category average, though the absolute score reflects mixed real-world performance in challenging listening environments. Speech in quiet is solid at 3.4/5, slightly above average. The Evolv AI does show weaknesses in two key areas. Own voice comfort scores 2.1/5, falling 0.65 points below the category average, which may affect how natural your own speech sounds. Feedback handling, while solid in absolute terms at 3.5/5, runs 1.21 points below the category average of 4.71/5—meaning competitors in this price tier generally offer better feedback suppression. At this premium price point, several alternatives deliver stronger overall performance, including the Phonak Sphere Infinio and Oticon Intent. However, the Evolv AI's Expert's Choice Award recognition in 2023 and 2024 reflects its practical strengths. This hearing aid may suit users who prioritize music streaming quality and improved speech understanding in noise over own-voice comfort, and who value Starkey's feature set including rechargeable batteries and hands-free calling for both iPhone and Android.
