Phonak Audéo Lumity vs Phonak Sphere Infinio

The Phonak Audéo Lumity is a premium prescription behind-the-ear hearing aid released in 2022, currently available at $4,398. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.3/5, ranking #11 among 36 prescription hearing aids tested. Speech performance is a clear strength for the Lumity. Speech in quiet scores an excellent 4.8/5, measuring 1.37 points above the category average. Speech in noise comes in at 2.3/5—above the category average by 0.75 points, though still mixed in absolute terms. This reflects a common challenge across the category rather than a specific shortcoming of this device. Music streaming quality is strong at 4.1/5, outperforming the category average by 1.46 points, making it a solid choice for users who frequently stream audio from their phone. Feedback handling is excellent at 5.0/5. However, own-voice comfort scores low at 1.0/5, falling 1.75 points below the category average—a notable weakness that some users may find bothersome. The Lumity is best suited for users who prioritize speech clarity and streaming quality and can tolerate potential own-voice discomfort. It has earned HearAdvisor's Expert's Choice Award in both 2023 and 2024. Buyers in this premium price range should also consider the higher-scoring Oticon Intent or newer Phonak Sphere Infinio if maximum performance is the priority.

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.
