PhonakSoundGrade A

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.

ZeppSoundGrade B

Zepp Clarity Omni

The Zepp Clarity Omni is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.9/5 in HearAdvisor's lab testing, placing it in the top 37% of OTC devices. At $399, this behind-the-ear rechargeable device offers solid overall performance with some standout strengths. The Omni's most impressive feature is its music streaming quality, scoring 3.6/5—a full 1.68 points above the OTC category average. This makes it one of the better choices for users who prioritize streaming audio from their iPhone or Android device. Feedback handling is excellent at 5.0/5, meaning users can expect stable performance without whistling during typical daily activities. Speech performance shows a more nuanced picture. Speech in quiet scores a solid 3.0/5, sitting 0.21 points above category average. Speech in noise, however, scores 1.9/5—above the category average by 0.40 points, but still low in absolute terms. Users in challenging listening environments like busy restaurants should set realistic expectations. Own-voice comfort scores 2.7/5, above category average but only mixed in absolute terms. The Zepp Clarity Omni is best suited for budget-conscious consumers who value excellent streaming audio quality and reliable feedback control, and who primarily need hearing support in quieter environments. Those frequently encountering noisy settings may want to consider alternatives with stronger speech-in-noise performance.
