Measured Performance

SoundScore: 5 Acoustic Dimensions

Five independent lab measurements evaluate speech in quiet, speech in noise, own-voice comfort, feedback control, and music streaming performance. 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 Performance Verdict

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.

Test Documentation

Olive Union Max Fit Observations and Configuration

Our lab notes document observations from both Initial and Tuned fit conditions during testing of the Olive Union Max. The recorded test configuration details the specific settings and parameters used throughout measurement.

Lab Notes

Initial fit observations

Out of the box with foam tips, the Olive Union Max achieves a normalized Initial Score of 3.4/5. Initial speech in quiet is limited at 1.9/5, while speech in noise measures 1.0/5. Music streaming performs well at 4.1/5, and feedback handling is excellent at 5.0/5 with no stability issues. Own-voice comfort is low at 1.6/5, suggesting some users may experience occlusion effects. The initial fit provides solid streaming and feedback performance but limited speech benefit without adjustment.

Tuned fit observations

After tuning while maintaining foam tips, the normalized Tuned Score improves modestly to 3.6/5—a gain of 0.2 points. Speech in quiet improves from 1.9/5 to 2.6/5, showing meaningful benefit from adjustment. However, speech in noise remains at 1.0/5, and own-voice comfort stays at 1.6/5. Music streaming holds steady at 4.0/5 with excellent feedback handling at 5.0/5. Tuning primarily benefits quiet-environment speech clarity while other metrics remain largely unchanged.
