PhonakSoundScore 5.0Grade A

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.

Starkey Omega AI

The Starkey Omega AI is a premium behind-the-ear prescription hearing aid released in 2025, currently available at $3,998. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.5/5, placing it at #13 among 39 prescription hearing aids tested. This device demonstrates notable strengths in speech performance. Speech in quiet scored 3.9/5, a solid result that sits 0.54 points above the category average. Speech in noise measured 2.9/5—above the category average by 0.75 points, though only mixed in absolute terms at under 3.0/5. Music streaming quality also performs well at 3.2/5, sitting 0.44 points above average for the category. Feedback handling is excellent at 4.6/5 in absolute terms, though it falls slightly below the category average by 0.12 points. Own-voice comfort scored 2.7/5, matching the category average exactly—a mixed result that some users may find noticeable depending on their sensitivity to occlusion effects. The Omega AI includes modern connectivity features like iPhone and Android streaming, hands-free calling capability, and rechargeable batteries. Buyers in this premium price tier should note that several competitors—including the Phonak Sphere Infinio and Oticon Intent—scored higher in our lab testing. The Starkey Omega AI is best suited for users who prioritize speech clarity in everyday listening situations and value Starkey's feature set and fitting approach.
