Independent Assessment

How the Lucid Ultra 128 Performed in Lab Testing

The Lucid Ultra 128 is a premium behind-the-ear prescription hearing aid priced at $5,000, earning an A grade with a SoundScore of 4.4/5 in our lab testing. It ranks #17 among 39 prescription hearing aids tested, placing it in the top 41% of its category.

Speech performance is where the Lucid Ultra 128 truly excels. In our lab testing, speech in quiet scored a strong 4.3/5, which is 0.95 points above the category average. Speech in noise performance reached 2.7/5, which sits above the category average by 0.59 points, though it remains mixed in absolute terms. This suggests the device handles conversational clarity well in our test scenarios, particularly in quieter environments.

The device does face some challenges. Feedback handling scored just 1.7/5, falling 3.02 points below the category average of 4.72/5—a notable weakness compared to other prescription aids in our testing. Music streaming also came in below average at 2.3/5, which is 0.46 points under the category norm. Own-voice comfort scored a mixed 2.9/5, slightly above average.

At this price point, several competitors in our database achieved higher overall scores, including the Phonak Sphere Infinio and Oticon Intent. The Lucid Ultra 128 features disposable batteries and supports both iPhone and Android streaming. It may appeal to users who prioritize speech clarity in quiet settings and are less concerned about feedback stability or music streaming fidelity in our standardized tests.

Test Documentation

Fit Observations and Configuration for the Lucid Ultra 128

Our technicians documented observations from both Initial and Tuned fit conditions during testing. The notes below detail the specific test configuration and any relevant findings from the measurement session.

Lab Notes

Initial fit observations

In initial fit testing with a closed vented dome and standard receiver, the Lucid Ultra 128 achieved a normalized score of 4.4/5. Speech in quiet measured 4.0/5, while speech in noise reached 2.2/5. Feedback handling was excellent at 5.0/5 in this configuration. Own-voice comfort scored 2.9/5 and music streaming came in at 2.5/5. The initial fit demonstrated strong out-of-box stability with solid speech clarity in quiet conditions.

Tuned fit observations

After tuned fitting—still using a closed vented dome and standard receiver—the normalized score measured 4.2/5, a slight decrease of 0.2 points from initial fit. Speech in quiet improved to 4.3/5 and speech in noise increased to 2.7/5, both above category averages. However, feedback handling dropped significantly to 1.7/5, well below the 4.72 category average. Own-voice comfort remained at 2.9/5 while music streaming decreased slightly to 2.3/5.
