Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Olive Union Max
The Olive Union Max is a behind-the-ear OTC hearing aid priced at $190, earning a B grade with a SoundScore of 3.4/5 in HearAdvisor's lab testing. This budget-friendly device ranks #41 of 65 OTC hearing aids tested. In our lab testing, the Max shows a distinctive performance profile with clear strengths and limitations. Music streaming stands out with a strong 4.0/5 score, measuring 2.08 points above the OTC category average—making it one of the better choices for audio entertainment. Feedback handling is excellent at 5.0/5, meaning the device maintains stability without whistling during typical daily activities. However, speech performance presents challenges. Speech in quiet scores a mixed 2.6/5, falling 0.21 points below the category average, while speech in noise is low at 1.0/5, measuring 0.48 points below average. Own-voice comfort also scores low at 1.6/5, sitting 0.91 points below the category average—users may notice their own voice sounds unnatural or hollow. The Olive Union Max is best suited for budget-conscious consumers who prioritize music and media streaming over demanding listening environments. Those who frequently need to follow conversations in noisy settings like restaurants or social gatherings may find the speech-in-noise limitations frustrating. For basic amplification in quieter environments with excellent streaming quality at an accessible price point, the Max offers reasonable value despite its speech performance trade-offs.

Zepp Clarity Pixie
The Zepp Clarity Pixie is a mid-priced OTC hearing aid featuring an invisible-in-ear design, priced at $999. In our lab testing, it earned a B grade with a SoundScore of 3.6/5, placing it in the top 48% of the OTC hearing aid category. This device delivers solid speech clarity in quiet environments, scoring 3.6/5—notably 0.77 points above the category average. Speech understanding in noisy settings scores 1.7/5, which is above the category average but low in absolute terms, indicating modest benefit when background noise is present. Feedback handling is strong at 4.3/5, though slightly below the category average of 4.54/5. The Pixie shows significant limitations in certain areas. Own-voice comfort scores 1.5/5, falling 1.01 points below the category average, which may result in a noticeable hollow or boomy quality to your own voice. Music streaming capability is essentially absent, scoring 0.0/5—nearly 2 points below average—making this device unsuitable for those who prioritize streaming audio quality. The invisible-in-ear form factor offers excellent discretion, and the device includes rechargeable batteries with both iPhone and Android streaming connectivity. However, shoppers in this price range should note that several competitors offer substantially higher sound performance. The Zepp Clarity Pixie may appeal to those prioritizing an ultra-discreet design and strong speech clarity in quiet settings, but listeners who value streaming music or need better noise management may find better options elsewhere in this price tier.
