HSKLock Hearing Aid Expert Review

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

In the initial fit condition using a closed dome coupling, the HSKLock Hearing Aid delivered below-average speech intelligibility performance in our lab testing. Speech in quiet scored 2.00/5, while speech in noise measured just 0.10/5—well below the amplifier category average. The device excelled in feedback handling with a perfect 5.00/5 score, and own-voice comfort measured above average at 2.80/5, suggesting reasonable occlusion management. The overall initial fit score of 1.73/5 reflects the device's limitations in core speech understanding tasks despite its stability advantages.
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.
