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.

ReSound OMNIA RIE
The ReSound OMNIA RIE is a premium prescription behind-the-ear hearing aid released in 2022, currently available at $4,498. In HearAdvisor's lab testing, it earns a B grade with a SoundScore of 3.9/5, ranking #31 of 39 devices in the prescription hearing aid category. This device shows notable strengths in speech clarity for quiet environments, scoring 3.7/5—a solid result that sits 0.34 points above the category average. Own-voice comfort also performs above average at 3.0/5, which may appeal to users who find their own voice bothersome in other devices. Feedback handling is strong in absolute terms at 4.1/5, though it falls 0.62 points below the category average of 4.72/5. The OMNIA RIE's most significant limitation is speech in noise performance, scoring just 1.0/5—a low result that trails the category average by 1.11 points. For users who frequently encounter challenging listening environments like restaurants or group conversations, this represents a meaningful gap compared to alternatives. Music streaming scores a mixed 2.7/5, essentially matching the category average. The device offers flexible power options with both rechargeable and disposable batteries, plus streaming compatibility with iPhone and Android devices including hands-free functionality. However, at this premium price point, several competitors deliver stronger overall performance, including options from Phonak, Oticon, and Widex. The OMNIA RIE may suit users who prioritize quiet-environment clarity and own-voice comfort over noise-handling capabilities.
