Lucid Engage Hero
LucidSoundScore 4.2Grade A

Lucid Engage

The Lucid Engage is a mid-priced behind-the-ear OTC hearing aid that earns an A grade with a SoundScore of 4.2/5 in our lab testing. Priced at $850, it ranks #14 among 65 OTC hearing aids tested, placing it in the top 20% of its category. Speech performance is a notable strength. Speech in quiet scores a strong 4.3/5, which is 1.46 points above the OTC category average of 2.79/5. Speech in noise comes in at 2.4/5—above the category average by 0.94 points, though only mixed in absolute terms at 2.4/5. Own-voice comfort is solid at 3.6/5, exceeding the category average by 1.09 points. The Engage does have limitations. Feedback handling scores 2.6/5, falling 1.94 points below the category average of 4.54/5. Music streaming is mixed at 2.4/5, though still 0.48 points above the OTC average. These results suggest the device prioritizes speech clarity over other use cases. This rechargeable BTE supports both iPhone and Android streaming. It received HearAdvisor's Expert's Choice Award in both 2023 and 2024. The Lucid Engage is best suited for consumers who prioritize conversational clarity and want an A-grade performer without prescription-level prices, though those sensitive to feedback or who stream music frequently may want to consider alternatives like the higher-scoring Sony CRE-E10 or Yeasound RIC800 in the same price range.

Sennheiser All-Day Clear Slim Hero
SennheiserSoundScore 4.1Grade A

Sennheiser All-Day Clear Slim

The Sennheiser All-Day Clear Slim is a premium OTC behind-the-ear hearing aid priced at $1,499, earning an A grade with a SoundScore of 4.1/5. This places it in the top 23% of OTC hearing aids tested in our lab, ranking #16 among 65 devices in its category. This device excels in areas that reflect Sennheiser's audio heritage. Music streaming quality is a standout strength, scoring 3.8/5—a solid result that's 1.88 points above the OTC category average. Feedback handling is excellent at 5.0/5, meaning users can expect stability without whistling during typical use. Speech in quiet environments also performs well at 3.6/5, sitting 0.85 points above average for the category. However, the All-Day Clear Slim shows limitations in other areas. Speech in noise scores 1.5/5, matching the category average but representing a low absolute score that may challenge users in noisy restaurants or group conversations. Own-voice comfort is below average at 1.9/5, which could affect how natural users sound to themselves during conversation. The All-Day Clear Slim is best suited for consumers who prioritize music streaming and media consumption alongside hearing support, and who spend more time in quieter environments. Those frequently navigating noisy social situations may want to compare against higher-ranked competitors in this price range, such as the Lucid Tala or Audicus Omni 2, which achieve stronger overall scores.
