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.

Sony CRE-C10

The Sony CRE-C10 is an invisible-in-ear OTC hearing aid priced at $798, earning an A grade with a SoundScore of 4.2/5 in our lab testing. This places it at #12 of 65 devices in the OTC category, putting it in the top 17% of tested OTC hearing aids. Speech performance is where this device truly shines. Speech in quiet scores an excellent 4.5/5, a full 1.71 points above the category average of 2.79/5. Speech in noise performance at 2.9/5 is mixed in absolute terms, though still 1.39 points above the category average of 1.48/5. These speech clarity strengths have contributed to the CRE-C10 earning Expert's Choice recognition in both 2023 and 2024. The device does have notable limitations. Music streaming scores 0.0/5, which is 1.92 points below the category average—this device is not designed for audio entertainment. Feedback handling scores a solid 3.5/5 in absolute terms, though this is 1.04 points below the category average of 4.54/5. Own-voice comfort is mixed at 2.6/5, essentially matching the category average. The Sony CRE-C10 is best suited for consumers who prioritize speech understanding over streaming capabilities and want a discreet, invisible-in-ear form factor. Those who frequently stream music or media should consider alternatives like the Sony CRE-E10, which scores higher overall in this price range.
