The Autiphon U0 Series is a budget amplifier with excellent feedback handling, best for occasional light-listening situations.

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 Autiphon U0 Series.
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 Curve
The graph below plots measured insertion gain against prescriptive targets across the frequency range. This visualization shows how closely the amplification curve follows established fitting guidelines for the test conditions.
Audio Samples
These manikin-captured recordings let you hear how the U0 Series processes speech and environmental sounds. A reference recording provides a baseline for comparison under the same acoustic conditions.

Test Documentation
Our technicians documented observations for both Initial and Tuned fit conditions during testing. The notes below detail the test configuration and any fit-related findings from the measurement sessions.
In initial fit testing with closed dome coupling, the Autiphon U0 Series achieves a normalized score of 2.9/5. Speech in quiet measures 2.3/5, slightly above the category average. Speech in noise is limited at 1.0/5, below category norms. The device excels in feedback handling with a perfect 5.0/5 score. Music streaming is not functional, scoring 0.0/5. This out-of-box configuration provides basic amplification suited primarily for quiet environments.
The tuned fit evaluation maintains closed dome coupling and produces identical results to the initial fit, with a normalized score of 2.9/5. All component metrics remain unchanged: speech in quiet at 2.3/5, speech in noise at 1.0/5, feedback handling at 5.0/5, and music streaming at 0.0/5. The lack of improvement between fits reflects the device's limited adjustment capabilities as a basic amplification product.
