Lucid Engage

The Lucid Engage is a mid-priced OTC hearing aid that earned an A grade with a SoundScore of 4.2/5 in our lab testing, ranking #14 among 65 OTC devices tested. Priced at $850, this behind-the-ear rechargeable device has received our Expert's Choice Award in both 2023 and 2024. In our testing, the Engage demonstrated strong speech clarity in quiet environments, scoring 4.3/5—a full 1.46 points above the OTC category average. Speech understanding in noisy settings scored 2.4/5, which is above the category average by 0.94 points but remains mixed in absolute terms. Own-voice comfort was solid at 3.6/5, exceeding the category average by over a point, which should help with natural-sounding self-perception during conversations. The device's main weakness is feedback handling, scoring 2.6/5—nearly 2 points below the category average of 4.54/5. Users may experience more whistling or feedback artifacts compared to other OTC options. Music streaming quality was mixed at 2.4/5, slightly above average but not a standout feature. The Lucid Engage is well-suited for consumers prioritizing speech clarity in everyday quiet-to-moderate listening situations who can accept trade-offs in feedback stability. Buyers in this price range may also consider alternatives like the Sony CRE-E10 or Lexie B2 Plus, which scored higher in our testing. The Engage supports both iPhone and Android streaming and offers rechargeable convenience.

Phonak Audéo EON Sphere

The Phonak Audéo EON Sphere is a premium behind-the-ear prescription hearing aid priced at $4,398. In HearAdvisor's lab testing, it earned a SoundScore of 5.0/5 and an A grade, placing it among the top performers in the prescription hearing aid category. Speech performance stands out as this device's greatest strength. Speech in noise scored an excellent 4.5/5, a full 2.53 points above the category average of 1.96/5—a substantial margin that makes this one of the strongest performers in challenging listening environments. Speech in quiet also performed well at 4.3/5, nearly a full point above the category average. These results suggest the Audéo EON Sphere may be particularly well-suited for users who frequently encounter noisy social settings or group conversations. Music streaming delivered a solid 3.7/5, more than a point above the category average of 2.64/5, indicating above-average audio fidelity for phone-streamed content. Own-voice comfort scored 2.8/5, which sits just above the category average but reflects mixed absolute performance—users sensitive to occlusion effects should discuss this with their hearing care provider. Feedback handling scored an excellent 4.6/5 in absolute terms, though it lands slightly below the category average of 4.71/5. The Audéo EON Sphere represents Phonak's latest premium technology and delivers strong results across most metrics in our standardized testing. It's best suited for users prioritizing speech clarity in difficult listening situations who are prepared for the premium price point.
