How We Test

The Olive Union Max is a behind-the-ear OTC hearing aid priced at $190, earning a B grade with a SoundScore of 3.0/5 in our lab testing. This budget-tier device presents a mixed performance profile with notable strengths in specific areas alongside significant limitations in core speech functionality.

The standout feature of the Olive Union Max is its music streaming quality, scoring a strong 4.0/5—an impressive 2.07 points above the OTC category average. Feedback handling is equally impressive at 5.0/5, meaning users can expect excellent stability without whistling or squealing during normal use.

However, the device shows substantial weaknesses in speech performance. Speech in quiet scores a mixed 2.4/5, sitting 0.24 points below the category average. More concerning is the speech in noise performance at -0.3/5, which falls 1.43 points below average—this represents a significant limitation for users who need to communicate in challenging acoustic environments. Own-voice comfort also trails at 1.6/5, registering 0.89 points below average.

The Olive Union Max may suit budget-conscious consumers who prioritize music streaming and stable feedback control over speech clarity in difficult listening situations. Those who frequently encounter noisy environments or require strong speech performance should consider alternatives. Several devices in the OTC category offer comparable or better sound scores at lower price points.

Fit Conditions

Initial and Tuned Test Results for the Olive Union Max

We measured the Olive Union Max in both its out-of-box Initial fit and after completing the manufacturer's Tuned personalization process. The summaries below describe how each configuration performed against prescription targets.

Lab Test Summary

In initial fit testing with foam tips and the manufacturer's proprietary default formula, the Olive Union Max achieved a normalized score of 2.9/5. Music streaming performed well at 4.1/5, and feedback handling was excellent at 5.0/5. However, speech performance was limited, with speech in quiet at 1.9/5 and speech in noise at -0.4/5. Own-voice comfort measured 1.6/5. The out-of-box experience delivers strong media playback but falls short for conversational clarity.

What is HearAdvisor's Initial Fit?

The Initial Fit approximates the most likely settings and eartips for a typical moderate hearing loss. Results are measured across the same 72 acoustic scenes in our custom-built lab, then scored on a 5-star scale using an auditory model.
