Fit Conditions
Lab Test Summary for the Styletto C&G IX
We measured this device under both Initial and Tuned fit conditions to evaluate its out-of-box performance and response to professional adjustment. The summaries below describe findings for each configuration.
In the initial fit configuration with vented sleeve coupling, the Styletto C&G IX achieved a normalized Initial Score of 4.6/5—the strongest of its two test conditions. Speech in quiet measured 4.0/5, while speech in noise scored 2.6/5. Feedback handling performed well at 4.6/5, closer to the category average in this out-of-box state. Own-voice comfort scored a solid 3.7/5, and music streaming measured 2.7/5. This initial setup delivers strong overall sound quality with minimal professional adjustment required.
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.
