This behind-the-ear device ranks #19 among 65 OTC hearing aids tested, placing it in the top 28% of its category. Speech clarity is where this device truly excels.

Speech in noise measures 2.6/5—above the category average by 1.09 points, though only mixed in absolute terms. For conversations in calm settings, the EH-Z1500 delivers strong performance that outpaces most OTC competitors. However, this device has notable limitations. Music streaming is not supported, scoring 0.0/5 and falling 1.92 points below the category average. Feedback handling scores a solid 3.8/5 in absolute terms, though this sits 0.74 points below the category average of 4.54/5. Own-voice comfort is mixed at 2.4/5, roughly in line with category norms. The EH-Z1500 uses disposable batteries and a tulip dome coupling. For those prioritizing speech intelligibility in quieter environments over streaming capabilities, this device offers solid value. However, buyers who want music streaming or need strong noise performance should consider alternatives like the Sony CRE-E10 or Lexie B2 Plus in this price range.

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.
