Performance Metrics

SoundScore: 5 Acoustic Dimensions

Our lab rated the Olive Union Max on five independent metrics including speech in quiet, speech in noise, own-voice comfort, feedback control, and music streaming. Each score below reflects standardized acoustic measurements. The purple SoundScore graph is the overall result, and the five graphs after it break it into individual measurements for the selected fit. Each curve shows how scores are spread across all tested hearing aids, and the dot and number mark the score for Olive Union Max.

Lab Assessment

Olive Union Max Verdict

The Olive Union Max is a budget-priced OTC hearing aid released in 2024, earning a B grade with a SoundScore of 3.5/5 in HearAdvisor's lab testing. At $190, it positions itself as an affordable entry point into the OTC hearing aid market.

In our testing, the Max demonstrates a distinctive performance profile with notable strengths in music streaming and feedback handling. The music streaming score of 4.0/5 is strong in absolute terms and stands out at 2.08 points above the OTC category average—making it one of the better options for users who prioritize phone audio quality. Feedback handling is excellent at 5.0/5, sitting 0.46 points above average, meaning users can expect stable performance without whistling during typical wear.

However, speech performance presents limitations. Speech in quiet scores a mixed 2.6/5, falling 0.21 points below the category average. More notably, speech in noise is low at 1.0/5, which is 0.48 points below average—a meaningful gap for users who need help understanding conversation in challenging environments. Own-voice comfort is also low at 1.6/5, trailing the category average by 0.91 points, which may result in noticeable occlusion effects.

The Olive Union Max may suit budget-conscious consumers who prioritize music and media streaming over speech clarity in difficult listening situations. Those who frequently navigate noisy environments or need stronger speech support may want to consider alternatives with better speech-in-noise performance.

Test Configuration

Olive Union Max Lab Notes

Our technicians documented the specific settings and conditions used when measuring the Olive Union Max. Review the configuration details below to understand exactly how we conducted this evaluation.

Lab Notes

Initial fit observations

Out of the box with foam tip coupling, the Olive Union Max achieves a normalized Initial Score of 3.4/5. Speech in quiet starts at 1.9/5, while speech in noise measures 1.0/5—both below what typical users might expect for conversational clarity. Feedback handling is excellent at 5.0/5, and music streaming performs well at 4.1/5. Own-voice comfort is low at 1.6/5. The initial fit prioritizes stability and streaming quality over speech benefit, delivering consistent but limited speech support without adjustment.

Tuned fit observations

After tuning with the same foam tip coupling, the normalized Tuned Score improves modestly to 3.6/5, a gain of 0.2 points. Speech in quiet rises to 2.6/5, showing meaningful improvement, though speech in noise remains at 1.0/5. Feedback handling stays excellent at 5.0/5, and music streaming holds steady at 4.0/5. Own-voice comfort remains unchanged at 1.6/5. The tuning process yields incremental speech benefit in quieter settings but does not address the device's limitations in noisy environments.
