Summary
In the initial fit condition using a vented sleeve coupling with the 110/46 receiver, the Signia Pure C&G BCT IX achieved an above-average fit score of 3.35. Speech in quiet (3.90) and speech in noise (2.40) both exceeded category averages, with noise performance being particularly strong. Own-voice comfort measured well above average at 3.80, suggesting effective occlusion management even with relatively open coupling. Music streaming (2.50) and feedback handling (4.20) were slightly below category averages. The manufacturer's proprietary IXFit formula provided solid out-of-box performance without requiring significant adjustment.
The tuned fit condition retained the same vented sleeve coupling and 110/46 receiver configuration, with adjustments made using the IXFit formula. This resulted in modest improvements across speech metrics: speech in quiet increased to 4.10 and speech in noise to 2.60. Music streaming also improved slightly to 2.70. The overall fit score rose by 0.15 points to 3.49—above average for the category. Feedback handling and own-voice scores remained unchanged, indicating the initial configuration was already well-optimized for stability and occlusion control.
