Quality data starts with quality recordings. HearAdvisor worked with GRAS to build a no-compromise front end so every test is repeatable and reliable.
Lab Assessment
Lexie B3 Performance Verdict
Our testing team analyzed the Lexie B3 across five key performance dimensions to determine its overall effectiveness. The verdict below reflects measured outcomes from controlled laboratory conditions.
The Lexie B3 delivers top-tier OTC sound quality with excellent speech clarity, making it ideal for budget-conscious buyers seeking reliable performance.
- Excellent speech in quiet environments4.5/5
- Strong feedback handling4.6/5
- Above-average music streaming+1.38 vs category
- Speech in noise is above average but only mixed overall2.5/5
Fit Conditions
Lexie B3 Initial and Tuned Results
We evaluated the Lexie B3 in both its factory-default Initial fit and an optimized Tuned configuration. The summaries below detail how each condition performed against prescription targets.
In its initial out-of-box configuration with tulip dome coupling, the Lexie B3 achieves an excellent normalized Initial Score of 4.8/5. Speech-in-quiet performance is excellent at 4.5/5, substantially exceeding the category average by 1.73 points. Speech-in-noise scores 2.5/5—above the category average by 1.02 points, though mixed in absolute terms. Feedback handling is excellent at 4.6/5, while own-voice comfort is solid at 3.0/5. Music streaming quality reaches 3.3/5, a solid result that outperforms the typical OTC device by 1.38 points.
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.
