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 independent lab testing, it earned an A grade with a SoundScore of 4.1/5, ranking #23 among 39 prescription hearing aids tested. This device demonstrates particular strength in music streaming, scoring 4.1/5—a strong result that sits 1.34 points above the category average. Feedback handling is excellent at 5.0/5, providing reliable stability during wear. Speech clarity in quiet environments is solid at 3.7/5, measuring 0.29 points above average for prescription aids. However, the Lumity shows notable limitations. Own-voice comfort scores just 1.0/5, falling 1.70 points below the category average—a significant weakness that may affect user satisfaction during conversations. Speech understanding in noisy environments, while technically above average by 0.04 points, remains mixed in absolute terms at 2.1/5. The Audéo Lumity includes rechargeable batteries, streaming compatibility with both iPhone and Android devices, and hands-free calling capability. It received HearAdvisor's Expert's Choice Award in both 2023 and 2024. This hearing aid may suit users who prioritize music enjoyment and streaming quality, though those sensitive to own-voice perception or frequently in noisy environments may want to explore alternatives in this price tier.

Phonak Sphere Infinio
The Phonak Sphere Infinio is a premium behind-the-ear prescription hearing aid released in 2024, priced at $4,898. In our lab testing, it earned an A grade with a SoundScore of 5.0/5, placing it at #2 among 39 prescription hearing aids tested—within the top 3% of its category. The standout performance comes in speech clarity. Speech in noise scores an excellent 4.7/5, a remarkable 2.59 points above the category average of 2.11/5. Speech in quiet also impresses at 4.5/5, sitting 1.07 points above average. For anyone who struggles to follow conversations in restaurants, gatherings, or busy environments, this device delivers measurably superior intelligibility compared to most alternatives we've tested. Music streaming quality is strong at 4.0/5, exceeding the category average by 1.24 points—a meaningful advantage for users who value audio fidelity when streaming from phones. However, own-voice comfort is mixed at 2.3/5, falling 0.40 points below the category average, which may affect how natural your own speech sounds. Feedback handling, while solid in absolute terms at 3.6/5, sits 1.12 points below the category average of 4.72/5. The Sphere Infinio is best suited for users prioritizing exceptional speech understanding, particularly in challenging noise environments, and who are willing to invest at the premium tier. Those especially sensitive to own-voice quality or requiring maximum feedback stability may want to compare alternatives like the similarly-priced Oticon Intent or the lower-priced Phonak Audéo EON Sphere.
