Summary
In the initial fit condition using Power Dome with Slits coupling, the Eargo 8 delivered mixed results. Speech in quiet scored 1.90/5, below the category average, while speech in noise was particularly weak at -0.20/5. The device excelled in feedback handling with a perfect 5.00/5 score, and own-voice comfort measured above average at 3.20/5, indicating good occlusion management despite the in-ear design. The overall initial fit score of 1.67/5 was below average, suggesting limited out-of-box speech benefit for the target hearing loss profile.
The tuned fit condition retained the same Power Dome with Slits coupling and showed modest improvement, with the overall fit score increasing by 0.29 points to 1.96/5. Speech in quiet improved to 2.60/5, and speech in noise rose to 0.30/5, though both remained below category averages. Feedback handling decreased to 4.20/5, falling below average in this configuration. Own-voice comfort remained stable at 3.20/5. The limited coupling options and proprietary fitting formula constrained the tuning potential in our standardized protocol.
