Fit Conditions
iHear MatriX Performance Across Initial and Tuned Settings
We tested the iHear MatriX in both its Initial factory configuration and after Tuned adjustments using the manufacturer app. Toggle between conditions below to compare how each fit performs against prescription targets.
Out of the box with Power Dome coupling, the iHear MatriX achieved a normalized Initial Score of 3.2/5. Speech in quiet measured 1.8/5 and speech in noise 1.6/5—both below the device's tuned potential. Feedback handling was excellent at 5.0/5, and own voice comfort scored 2.7/5. Music streaming scored 0.0/5. The initial fit provides basic functionality but leaves meaningful room for improvement through tuning adjustments.
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.
Measured Performance
