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.

RCA In-Ear
The RCA In-Ear is a budget-priced OTC hearing aid available for $249, earning a C grade with a SoundScore of 2.8/5 in our lab testing. This places it near the bottom of the OTC hearing aid category, ranking 64th out of 65 devices tested. In our standardized testing, the RCA In-Ear shows a mixed performance profile. Its standout strength is excellent feedback handling, scoring a perfect 5.0/5—0.46 points above the category average. This means users are unlikely to experience whistling or squealing during normal wear. Own-voice comfort scores 2.6/5, which is essentially at the category average (+0.09 points), offering mixed but acceptable performance for how your own voice sounds while wearing the devices. However, the core speech performance metrics present significant limitations. Speech in quiet scores just 1.0/5, falling 1.79 points below the category average, and speech in noise also scores 1.0/5, sitting 0.48 points below average. Music streaming scored 0.0/5, indicating this device is not suitable for audio entertainment purposes. At this price point, buyers have considerably stronger options. Competitors like the Lucid Enrich Pro and JLab Hear OTC offer better sound performance at lower prices. The RCA In-Ear may appeal to those prioritizing feedback-free wear above speech clarity, but most users seeking meaningful hearing benefit should consider higher-performing alternatives in this budget segment.
