Choice

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.

Signia Styletto AX
The Signia Styletto AX is a premium prescription behind-the-ear hearing aid that earned an A grade with a SoundScore of 4.3/5 in our lab testing, ranking #21 of 39 prescription hearing aids tested. Priced at $4,398, this 2022 release features a distinctive slim design with rechargeable batteries and iPhone streaming capability. In our testing, the Styletto AX demonstrated strong speech clarity in quiet environments, scoring 4.0/5—0.63 points above the category average. Speech in noise performance was above average at 2.3/5 (+0.17 vs category), though this remains mixed in absolute terms, suggesting challenging listening situations may still require additional strategies. Own-voice comfort scored a solid 3.0/5, sitting 0.30 points above average. Music streaming quality measured 3.1/5, performing 0.34 points above the category average for solid audio fidelity when streaming from compatible devices. Feedback handling scored 3.9/5—solid in absolute terms, though 0.82 points below the category average of 4.72/5, which is worth noting if feedback stability is a priority. The Styletto AX has earned Expert's Choice Awards in both 2023 and 2024. However, buyers in this premium price tier should be aware that several competitors offer higher SoundScores, including the Phonak Sphere Infinio (4.98/5) and Oticon Intent (4.83/5). The Styletto AX may appeal most to those prioritizing its sleek aesthetic and strong quiet-environment speech performance over maximum scores in noise or feedback handling.
