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

Linner Nova Earbud
The Linner Nova Earbud is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.4/5 in HearAdvisor lab testing. At $299, it ranks #39 of 65 OTC hearing aids tested, placing it in the top 58% of its category. This device shows a distinctive performance profile with clear strengths and weaknesses. Music streaming is a standout at 4.5/5—an excellent score that sits 2.58 points above the category average. Feedback handling is equally impressive at 5.0/5, meaning users can expect stable performance without whistling during normal wear. These metrics suggest the Linner Nova excels as a streaming-capable earbud-style device. However, speech clarity metrics fall below category averages. Speech in quiet scores 2.1/5, which is 0.71 points below average and reflects mixed absolute performance. Speech in noise is low at 1.3/5, trailing the average by 0.19 points. Own-voice comfort is particularly challenged at 0.5/5—a low score that sits 2.01 points below the category average, meaning users may notice their own voice sounds unnatural or boomy. The Linner Nova Earbud may appeal to buyers who prioritize streaming audio quality and stable feedback-free wear over maximum speech benefit. Those seeking stronger speech clarity should consider alternatives in this price range like the Elehear Beyond (4.34/5) or Apple AirPods Pro 2 (4.04/5), which score higher overall.

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.
