Lucid Ultra 128  Hero
LucidSoundScore 4.4Grade A

Lucid Ultra 128

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.

SennheiserSoundScore 4.4Grade A

Sennheiser All Day Clear

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.
