Phonak Audéo Lumity vs Phonak Sphere Infinio Ultra

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 Ultra is a premium prescription behind-the-ear hearing aid released in 2026, priced at $4,898. In our lab testing, it earned an A grade with a SoundScore of 4.6/5, positioning it among the top performers in the Prescription Hearing Aid category. This device's standout strength is its exceptional speech performance. Speech in quiet scores an excellent 4.7/5, sitting 1.27 points above the category average of 3.43. Even more impressive is its speech-in-noise performance at 4.4/5—a strong score that lands 2.85 points above the category average of just 1.55/5. For listeners who struggle most in noisy environments like restaurants or social gatherings, these results are particularly noteworthy. Music streaming delivers a solid 3.3/5, coming in 0.66 points above category average. Own-voice comfort scores 2.8/5, which is above the category average but mixed in absolute terms—something to discuss with your hearing care provider if own-voice quality is a priority.
