Lab Assessment

Where the Sennheiser All Day Clear Performs

The Sennheiser All Day Clear is a mid-priced OTC hearing aid that earns an A grade with a SoundScore of 4.4/5, placing it in the top 8% of all OTC hearing aids tested in our lab. At $949, this behind-the-ear device delivers strong overall performance that stands out in a crowded category.

In our testing, the All Day Clear excels at speech clarity in quiet environments, scoring 4.0/5—a full 1.25 points above the OTC category average. Music streaming is another highlight, with a solid 3.3/5 score that's 1.38 points above average, making it one of the better choices for listeners who want quality audio beyond speech. Feedback handling is excellent at 5.0/5, meaning users shouldn't experience whistling issues during normal use.

Speech in noise presents a more nuanced picture. At 1.9/5, the score sits 0.39 points above the category average, but remains low in absolute terms—a common challenge across OTC devices. Own-voice comfort scores at 2.5/5, essentially matching the category average.

The Sennheiser All Day Clear is well-suited for users who prioritize clear speech understanding in everyday quiet-to-moderate listening situations and value high-quality audio streaming. Those frequently in noisy environments may want to manage expectations, though this limitation is shared across most OTC alternatives.

Test Documentation

Fit Observations for the All Day Clear

Our technicians documented observations from both the Initial and Tuned fit conditions during testing. The notes below detail the test configuration and any fitting considerations recorded during the evaluation.

Lab Notes

Initial fit observations

Out of the box with closed vented domes, the All Day Clear achieves a normalized Initial Score of 4.4/5. Speech in quiet performs strongly at 4.1/5, well above the 2.79 category average. Feedback handling is excellent at 5.0/5, and music streaming scores a solid 3.4/5. Speech in noise measures 1.9/5—above the category average of 1.48 but still low in absolute terms. Own-voice comfort sits at 2.5/5, typical for the category. The initial fit delivers impressive performance with minimal setup required.

Tuned fit observations

The tuned fit maintains the same closed vented dome coupling and achieves an identical normalized Tuned Score of 4.4/5. Performance remains consistent across metrics: speech in quiet at 4.0/5, speech in noise at 1.9/5, feedback handling at a perfect 5.0/5, own-voice comfort at 2.5/5, and music streaming at 3.3/5. The lack of change between fits indicates the manufacturer's default fitting approach is already well-optimized for our target hearing-loss profile.
