Phonak Audéo Lumity vs Phonak Sphere Infinio

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.
