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.

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.

The Zepp Clarity Omni is a behind-the-ear OTC hearing aid priced at $399, earning a B grade with a SoundScore of 3.9/5 in HearAdvisor's lab testing. This places it in the top 37% of the 65 OTC hearing aids we've tested, offering solid overall performance in the budget price tier. The standout feature of the Omni 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 stronger choices for users who prioritize phone audio streaming alongside hearing assistance. Feedback handling is excellent at 5.0/5, meaning users can expect stable performance without whistling during normal use. Speech clarity shows mixed results. Speech in quiet environments scores a solid 3.0/5, sitting 0.21 points above the category average. However, speech in noise scores 1.9/5—above the category average by 0.40 points, but still low in absolute terms. Users who frequently encounter noisy restaurants or group conversations may find performance limited in those situations. Own-voice comfort scores 2.7/5, which is above the category average but only mixed in absolute quality. The Zepp Clarity Omni is best suited for budget-conscious buyers who want reliable streaming audio and stable feedback performance, with adequate speech understanding in quieter settings. Those needing stronger speech-in-noise performance may want to explore alternatives like the higher-scoring Elehear Beyond in this price range.
