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.

Sontro Soundwave
The Sontro Soundwave is a mid-priced OTC hearing aid that earns a B grade with a SoundScore of 3.0/5 in our lab testing. At $849, this behind-the-ear device uses disposable batteries and sits in the lower tier of OTC performance, ranking #61 of 65 devices in its category. The Soundwave's strongest attribute is own-voice comfort, scoring 3.6/5—a solid result that sits 1.09 points above the OTC category average. This makes it relatively comfortable for wearers who are sensitive to hearing their own voice sound unnatural or boomy. However, other performance areas present significant limitations. Speech clarity scores are below average in both quiet and noisy environments. Speech in quiet scores 2.7/5 (0.12 points below average), while speech in noise drops to 1.2/5 (0.28 points below average). Feedback handling is a notable weakness at 2.5/5, falling 2.04 points below the category average of 4.54/5. Perhaps most limiting is the music streaming score of 0.0/5, indicating this device does not support phone audio streaming—a feature many competitors in this price range offer. Consumers prioritizing own-voice comfort on a moderate budget may find the Soundwave acceptable, but those seeking strong speech clarity or streaming capability should consider alternatives. Several higher-performing OTC devices are available at similar or lower price points, including options like the Lexie Lumen or HearingAssist Control that deliver comparable or better overall sound quality.
