Phonak Sphere Infinio
The Phonak Sphere Infinio is a premium behind-the-ear prescription hearing aid released in 2024, earning an A grade with a SoundScore of 4.6/5 in HearAdvisor's lab testing. Priced at $4,898, it ranks #2 among 36 tested prescription hearing aids, placing it in the top 3% of its category. In our testing, the Sphere Infinio demonstrated exceptional speech performance. Speech in noise scored 4.6/5, a full 3.05 points above the category average of 1.55/5—a standout result that sets this device apart from most competitors. Speech in quiet also excelled at 4.8/5, landing 1.37 points above average. These results suggest the Sphere Infinio may be particularly well-suited for users who prioritize understanding conversation in challenging listening environments like restaurants or group gatherings. Music streaming performance is strong at 4.0/5, sitting 1.36 points above the category average. The device supports both iPhone and Android streaming and features rechargeable batteries. However, own-voice comfort scored 2.3/5, which is mixed in absolute terms and 0.45 points below average. Feedback handling scored a solid 3.6/5 in absolute terms, though this falls 1.11 points below the category average of 4.71/5. The Sphere Infinio competes directly with other premium options like the Oticon Intent (4.75/5) and Signia Active Pro IX (4.61/5). Its exceptional speech-in-noise performance makes it a compelling choice for users who frequently encounter noisy environments, though those sensitive to own-voice quality or feedback stability may want to discuss these tradeoffs with their hearing care provider.

Widex Allure RIC 440
The Widex Allure RIC 440 is a premium prescription hearing aid that earns an A grade with a SoundScore of 4.5/5 in our lab testing, ranking #7 among 36 prescription hearing aids tested. At $4,398, it sits in the highest price tier and delivers excellent overall sound performance. Speech clarity is a standout strength for this device. Speech in quiet scores a strong 4.3/5, which is 0.87 points above the category average of 3.43/5. Speech in noise measures 2.5/5—above the category average of 1.55/5 by 0.95 points, though only mixed in absolute terms. Own-voice comfort is solid at 3.0/5, slightly above the 2.75/5 category average. The most significant limitation is feedback handling, which scores just 1.7/5 compared to a category average of 4.71/5. This represents a notable weakness that potential buyers should discuss with their hearing care provider. Music streaming performs at a mixed 2.7/5, essentially matching the category average. The Allure RIC 440 features Bluetooth streaming for both iPhone and Android devices, hands-free calling capability, and rechargeable batteries. It competes against other premium devices like the Oticon Intent (4.75/5) and Phonak Sphere Infinio (4.65/5). This hearing aid may suit those prioritizing speech understanding who can work with a provider to manage feedback, though its below-average feedback handling warrants careful consideration during fitting.
