Phonak Sphere Infinio Ultra

The Phonak Sphere Infinio Ultra is a premium behind-the-ear prescription hearing aid priced at $4,898. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.9/5, placing it in the top 3% of the 36 prescription hearing aids tested and ranking #2 in its category. This device delivers exceptional speech performance in our testing. Speech in noise scored an excellent 4.5/5, a remarkable 2.55 points above the category average of 1.96/5—one of the largest margins we've measured in this critical metric. Speech in quiet also performed strongly at 4.3/5, exceeding the category average by 1.00 point. These results suggest the Sphere Infinio Ultra prioritizes speech clarity across challenging listening environments. Music streaming quality is solid at 3.3/5, sitting 0.66 points above the category average. Own voice comfort scored 2.8/5, which is above the category average but remains mixed in absolute terms—listeners sensitive to occlusion may notice this limitation. Feedback handling measured 4.2/5, which is strong in absolute terms though 0.51 points below the category average of 4.71/5. The Sphere Infinio Ultra is best suited for users who prioritize speech understanding, particularly in noisy environments, and who are prepared to invest in premium technology. Those seeking the highest feedback stability or improved own-voice comfort may want to compare alternatives, though this device's speech performance stands out as a category leader.

Starkey Edge AI RIC

The Starkey Edge AI RIC is a premium prescription hearing aid released in 2024, priced at $5,000. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.4/5, ranking #18 among 36 prescription hearing aids tested. This behind-the-ear device demonstrates particular strength in speech clarity, scoring 4.1/5 for speech in quiet—0.76 points above the category average. Music streaming is a standout feature at 3.8/5, a solid score that sits 1.16 points above the prescription hearing aid average. Speech in noise performance scores 2.6/5, which is above the category average by 0.69 points but remains mixed in absolute terms, reflecting the inherent challenge of understanding speech in noisy environments. Feedback handling is excellent at 4.7/5, essentially matching the category average. Own-voice comfort scores 2.8/5, slightly above average but mixed overall—a common trade-off in hearing aids optimized for audibility. The device responded well to professional fitting, with the normalized Tuned Score reaching 4.7/5 compared to 4.2/5 at initial fit, a meaningful 0.5-point improvement. The Edge AI RIC earned HearAdvisor's 2024 Expert's Choice Award and offers iPhone and Android streaming with hands-free capability. At its premium price point, buyers should note that several competitors in the same price range achieve higher overall scores, including the Phonak Sphere Infinio (5.0/5) and Oticon Intent (4.85/5). This device may appeal to users who prioritize Starkey's ecosystem, strong speech-in-quiet performance, and above-average music streaming quality.
