PhonakSoundGrade A

Phonak Audéo EON Sphere

The Phonak Audéo EON Sphere is a premium behind-the-ear prescription hearing aid priced at $4,398. In HearAdvisor's lab testing, it earned a SoundScore of 5.0/5 and an A grade, placing it among the top performers in the prescription hearing aid category. Speech performance stands out as this device's greatest strength. Speech in noise scored an excellent 4.5/5, a full 2.53 points above the category average of 1.96/5—a substantial margin that makes this one of the strongest performers in challenging listening environments. Speech in quiet also performed well at 4.3/5, nearly a full point above the category average. These results suggest the Audéo EON Sphere may be particularly well-suited for users who frequently encounter noisy social settings or group conversations. Music streaming delivered a solid 3.7/5, more than a point above the category average of 2.64/5, indicating above-average audio fidelity for phone-streamed content. Own-voice comfort scored 2.8/5, which sits just above the category average but reflects mixed absolute performance—users sensitive to occlusion effects should discuss this with their hearing care provider. Feedback handling scored an excellent 4.6/5 in absolute terms, though it lands slightly below the category average of 4.71/5. The Audéo EON Sphere represents Phonak's latest premium technology and delivers strong results across most metrics in our standardized testing. It's best suited for users prioritizing speech clarity in difficult listening situations who are prepared for the premium price point.

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.
