ZeppSoundScore 3.9Grade B

Zepp Clarity Omni

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.
