Phonak Audéo Lumity
The Phonak Audéo Lumity is a premium prescription behind-the-ear hearing aid released in 2022, priced at $4,398. In HearAdvisor's lab testing, it earned a SoundScore of 4.1/5 (A grade), ranking #21 of 36 prescription hearing aids tested. This device demonstrates clear strengths in specific performance areas. Music streaming quality is strong at 4.1/5, scoring 1.46 points above the category average—a notable advantage for users who frequently stream audio from their phones. Feedback handling is excellent at 5.0/5, meaning the Lumity maintained stability without audible feedback during our standardized challenge tests. Speech in quiet environments also performs solidly at 3.7/5, measuring 0.37 points above the prescription category average. However, the Lumity shows a significant weakness in own-voice comfort, scoring just 1.0/5—a full 1.75 points below the category average. This low score suggests users may notice more occlusion or an unnatural quality to their own voice. Speech in noise performance is mixed at 2.1/5; while this is slightly above the category average (+0.19 points), it remains modest in absolute terms. The Audéo Lumity is best suited for users who prioritize excellent streaming quality and reliable feedback control, and who are less sensitive to own-voice occlusion effects. Those who struggle primarily with speech understanding in noisy environments may want to compare against higher-scoring competitors in this price range, such as the Phonak Sphere Infinio or Oticon Intent.

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.
