Quality data starts with quality recordings. HearAdvisor worked with GRAS to build a no-compromise front end so every test is repeatable and reliable.

The Olive Union Max is a budget OTC option with excellent feedback handling and strong music streaming, but struggles with speech clarity.
- Excellent feedback handling5.0/5
- Strong music streaming quality4.0/5, +2.07 vs category
- Budget-friendly price at $398
- Poor speech in noise performance-0.3/5
- Below-average own voice quality1.6/5
- Mixed speech in quiet clarity2.4/5
In its out-of-box configuration with foam tip coupling, the Olive Union Max achieved a normalized Initial Score of 2.9/5. Speech in quiet measured 1.9/5 while speech in noise scored -0.4/5, both reflecting limited speech benefit in our testing. Music streaming performed well at 4.1/5, and feedback handling was excellent at 5.0/5. Own-voice comfort scored 1.6/5, indicating noticeable occlusion effects. The initial setup provides reasonable performance for music and stability but limited speech enhancement.
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.
