Phonak Sphere Infinio

The Phonak Sphere Infinio is a premium behind-the-ear prescription hearing aid released in 2024, earning an A grade with a SoundScore of 4.6/5 in HearAdvisor's lab testing. Priced at $4,898, it ranks #2 among 36 tested prescription hearing aids, placing it in the top 3% of its category. In our testing, the Sphere Infinio demonstrated exceptional speech performance. Speech in noise scored 4.6/5, a full 3.05 points above the category average of 1.55/5—a standout result that sets this device apart from most competitors. Speech in quiet also excelled at 4.8/5, landing 1.37 points above average. These results suggest the Sphere Infinio may be particularly well-suited for users who prioritize understanding conversation in challenging listening environments like restaurants or group gatherings. Music streaming performance is strong at 4.0/5, sitting 1.36 points above the category average. The device supports both iPhone and Android streaming and features rechargeable batteries. However, own-voice comfort scored 2.3/5, which is mixed in absolute terms and 0.45 points below average. Feedback handling scored a solid 3.6/5 in absolute terms, though this falls 1.11 points below the category average of 4.71/5. The Sphere Infinio competes directly with other premium options like the Oticon Intent (4.75/5) and Signia Active Pro IX (4.61/5). Its exceptional speech-in-noise performance makes it a compelling choice for users who frequently encounter noisy environments, though those sensitive to own-voice quality or feedback stability may want to discuss these tradeoffs with their hearing care provider.

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 our lab testing, it earned an A grade with a SoundScore of 4.3/5, placing it at #2 among 36 prescription hearing aids tested—in the top 3% of its category. Speech performance is a clear strength. Speech in quiet scores a strong 4.0/5, sitting 0.57 points above the category average. Speech in noise performs 1.35 points above category average, though at 2.9/5 it remains mixed in absolute terms—better than most competitors but still challenging in demanding listening environments. Music streaming earns a solid 3.2/5, outpacing the category average by 0.56 points. Own-voice comfort scores 2.7/5, essentially matching the category average with a negligible 0.05-point difference below. Feedback handling is excellent at 4.6/5 in absolute terms, though this sits 0.11 points below the category average—reflecting how well prescription aids generally manage feedback rather than any significant weakness. The Omega AI competes in a crowded premium tier alongside devices like the Oticon Intent and Phonak Sphere Infinio, which score higher overall. However, Starkey's latest offering delivers strong speech clarity and above-average streaming quality. It's well-suited for users who prioritize speech understanding and want reliable Bluetooth connectivity with both iPhone and Android devices, along with hands-free calling capability.
