Summary
In the initial fit condition with a tulip dome, the Lexie Lumen delivered above-average speech in quiet performance (3.20/5) but below-average speech in noise (1.20/5). Own-voice comfort was a strength, scoring well above the category average at 3.70/5—reflecting the open coupling's minimal occlusion. Feedback handling measured 4.60/5, slightly below average for OTC devices. The overall initial fit score of 2.54/5 was above average, suggesting acceptable out-of-box performance for users seeking a simple setup with good own-voice comfort, though speech benefit in noise was limited.
Moving to a power dome configuration in the tuned fit condition produced substantial improvements. Speech in quiet rose to 4.10/5 and speech in noise jumped to 3.10/5—a significant gain that reflects better audibility from the more occluding coupling. Feedback handling reached a perfect 5.00/5, indicating excellent stability even with increased gain. The trade-off was own-voice comfort, which was not measured but typically worsens with tighter coupling. The tuned fit score of 2.89/5 represents a 0.35-point improvement over initial fit, demonstrating the value of proper fitting adjustments.
