Summary
In the initial fit condition using a power dome with slits, the EarCentric EX2 demonstrated well below average performance across speech metrics in our lab testing. Speech in quiet scored just 0.40 out of 5, while speech in noise registered a negative score of -0.50, indicating very limited benefit for understanding conversation. Feedback handling was a bright spot at 4.70 out of 5, suggesting stable operation without whistling. Own voice comfort scored below average at 2.30, reflecting moderate occlusion effects typical of the dome coupling used. The overall initial fit score of 0.90 reflects significant limitations in delivering audible speech benefit.
The tuned fit condition retained identical coupling (power dome with slits) and showed no measurable improvement over the initial fit in our testing. Speech in quiet and speech in noise scores remained unchanged at 0.40 and -0.50 respectively, suggesting limited adjustment capability or headroom in the device's fitting software. Feedback handling maintained its above-average 4.70 score. Own voice comfort was noted as above average in the tuned condition expert notes, though the numerical score remained at 2.30. The lack of improvement between fits indicates the device may have limited professional adjustment range to better match prescriptive targets.
