The EarCentric EX2 is a budget-priced prescription hearing aid best suited for buyers prioritizing low cost over sound performance.
Top 84% of Prescription Hearing AidHearAdvisor evaluated EarCentric EX2 across five independently measured lab metrics using the selected fit. The purple SoundScore graph is the overall result, and the five graphs after it break it into individual measurements for the selected fit. Each curve shows how scores are spread across all tested hearing aids, and the dot and number mark the score for EarCentric EX2.
Every hearing aid is lab-tested in two states — as it sounds out of the box, and after professional tuning. Switch fits to update the five metric graphs below.
How clearly speech comes through in calm, one-on-one surroundings.
Speech understanding against loud background noise — the toughest everyday test.
How natural your own voice sounds while wearing the aids, without a boomy, plugged-up quality.
Sound quality of music streamed to the hearing aids over Bluetooth.
Resistance to the whistling and squealing caused by acoustic feedback.
Lab Assessment
Quality data starts with quality recordings. HearAdvisor worked with GRAS to build a no-compromise front end so every test is repeatable and reliable.
Amplification Data
The graph below plots real-ear insertion gain measured on our test manikin against prescribed amplification targets. It shows how closely the EarCentric EX2 matched the expected frequency response curve across the speech range.
Audio Samples
Below are audio samples captured through the EarCentric EX2 on our acoustic manikin in controlled conditions. A reference recording is included so you can compare what the hearing aid delivers against the original signal.

Test Documentation
The notes below document how our technicians configured the EarCentric EX2 for testing, including fitting software settings and any adjustments made. This record ensures our measurements can be understood in proper context.
In initial fit testing with a power dome with slits coupling, the EarCentric EX2 achieved a normalized score of 2.7/5. Feedback handling was excellent at 4.7/5, providing stable performance. However, speech clarity was limited, with speech in quiet and speech in noise both scoring 1.0/5—significantly below category averages. Own-voice comfort was mixed at 2.3/5, and music streaming was not functional in our testing, scoring 0.0/5.
Professional tuning with the same power dome with slits coupling produced no improvement, with the normalized Tuned Score remaining at 2.7/5. All metrics—speech in quiet (1.0/5), speech in noise (1.0/5), feedback handling (4.7/5), own voice (2.3/5), and music streaming (0.0/5)—were unchanged from the initial fit. This suggests the device has limited adjustment range for optimizing speech audibility.
