OliveSoundScore 3.4Grade B

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.

In our testing, the All Day Clear excels at speech clarity in quiet environments, scoring 4.0/5—a full 1.25 points above the OTC category average. Music streaming is another highlight, with a solid 3.3/5 score that's 1.38 points above average, making it one of the better choices for listeners who want quality audio beyond speech. Feedback handling is excellent at 5.0/5, meaning users shouldn't experience whistling issues during normal use. Speech in noise presents a more nuanced picture.
