Summary
In the initial fit condition with vented sleeve coupling, the Signia Styletto C&G IX performed well above average overall. Speech in quiet scored 4.00/5, and speech in noise reached 2.60/5—both exceeding category norms. Own-voice comfort was a standout at 3.70/5, well above the category average, indicating minimal occlusion issues with the open fitting. Feedback handling measured 4.60/5, and music streaming scored 2.70/5. The initial fit score of 3.49/5 suggests good out-of-box sound quality with minimal professional adjustment required.
The tuned fit condition retained the same vented sleeve coupling, resulting in a slightly lower fit score of 3.32/5. Speech in quiet (3.90/5) and speech in noise (2.40/5) remained above average. Own-voice comfort held steady at 3.70/5. Feedback handling dropped to 3.60/5 in the tuned condition, falling below average. Music streaming improved to 3.10/5, approaching average performance. The minimal change in coupling meant gains in one area often came with trade-offs elsewhere, reflecting the inherent balance required in hearing aid optimization.
