Overall Assessment
Our Lab Verdict on the EarCentric EX2
The verdict card below summarizes our independent evaluation of the EarCentric EX2, including its overall grade, SoundScore, and category ranking. These results reflect standardized acoustic measurements conducted in our testing facility.
The EarCentric EX2 is a budget-priced prescription hearing aid with excellent feedback handling but significant limitations in speech clarity and streaming.
- Excellent feedback handling4.7/5
- Very affordable at $218
- Rechargeable batteries for convenience
- Low speech clarity in quiet0.4/5
- Poor performance in noisy settings
- No music streaming capability0.0/5
Fit Performance
EarCentric EX2 Fit Summaries from Our Lab
We measured the EarCentric EX2 in both Initial and Tuned fit conditions to assess how well each configuration performs. The summaries below describe the acoustic outcomes observed for each fit setting.
In initial fit testing with power dome with slits coupling, the EarCentric EX2 achieved a normalized score of 2.0/5. Feedback handling performed excellently at 4.7/5, providing stable wear. However, speech in quiet (0.4/5) and speech in noise (-0.5/5) scored low in absolute terms and well below category averages. Own-voice comfort measured 2.3/5, reflecting mixed performance. Music streaming scored 0.0/5, indicating this feature offers minimal utility in the out-of-box configuration.
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.
Metric Breakdown
How the EarCentric EX2 Scored Across Five Lab Metrics
Our testing evaluates five distinct performance areas: speech clarity in quiet, speech understanding in noise, own-voice naturalness, feedback control, and music streaming quality. The score card below shows how the EX2 measured in each category.
