Eargo 7 Score Breakdown
Our testing protocol evaluates five distinct performance areas using calibrated equipment and standardized procedures. The score card below shows how the Eargo 7 measured in speech clarity, noise handling, feedback control, own-voice comfort, and streaming quality.
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.
Scores use HearAdvisor’s public scoring scale and are based on measurements from our acoustic test chamber.
Fit Conditions
Eargo 7 Lab Test Summary
We measured the Eargo 7 in both Initial and Tuned configurations to document how performance changes with adjustment. Toggle between fit conditions below to compare the detailed results from each test session.
In the initial fit configuration using sleeve closed coupling, the Eargo 7 achieved a normalized score of 3.5/5. Speech in quiet performed well at 3.2/5, while speech in noise was limited at 1.1/5. Feedback handling was solid at 3.9/5, and own-voice comfort measured 2.9/5. Music streaming scored 0.0/5, indicating this feature is not functional. The initial fit delivers reasonable out-of-box performance for quiet environments.
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.
