Choice

Elehear Delight
The Elehear Delight is a budget-priced OTC hearing aid that delivers A-grade performance in our lab testing, earning a SoundScore of 4.3/5. At $315, it ranks #9 among 65 OTC hearing aids tested, placing it in the top 12% of its category. Speech clarity is a standout strength for this device. Speech in quiet scores a strong 4.0/5, measuring 1.21 points above the OTC category average of 2.79/5. Speech in noise performance is above the category average by 0.34 points, though the absolute score of 1.8/5 remains low—meaning challenging listening environments may still prove difficult. Music streaming quality is solid at 3.1/5, exceeding the category average by 1.18 points, making it a reasonable choice for audio enjoyment beyond speech. Feedback handling scores a strong 4.2/5 in absolute terms, though this falls 0.34 points below the category average of 4.54/5. Own-voice comfort scores 2.9/5, which is above the category average by 0.39 points but remains mixed in absolute terms—some users may notice their own voice sounds different than expected. The Elehear Delight represents strong value for budget-conscious consumers seeking quality speech performance in quieter environments. Those who frequently encounter noisy settings may find the device less capable, but for everyday conversation and media consumption, it performs well above typical OTC expectations at its price point.

Sontro Soundwave
The Sontro Soundwave is a mid-priced OTC hearing aid priced at $849, earning a B grade with a SoundScore of 3.1/5 in HearAdvisor's lab testing. This behind-the-ear device uses disposable batteries and ranks #61 of 65 OTC hearing aids tested, placing it in the top 92% of its category. In our lab testing, the Soundwave shows a notable strength in own-voice comfort, scoring 3.6/5—a solid result that sits 1.09 points above the category average. This suggests users may experience less of the "talking in a barrel" sensation that can occur with some hearing aids. However, the device faces challenges in other key areas. Speech in quiet scores 2.7/5 (mixed, 0.12 points below average), while speech in noise registers at 1.2/5 (low, 0.28 points below average), indicating potential difficulty in challenging listening environments. The most significant limitations appear in music streaming and feedback handling. Music streaming scores 0.0/5, falling 1.92 points below the category average—a notable weakness for users who value audio entertainment. Feedback handling scores 2.5/5, which is 2.04 points below the category average of 4.54/5, suggesting the device may be more prone to whistling issues. At this price point, competitors offer substantially stronger performance. Devices like the Sony CRE-E10 and Lexie B2 Plus deliver significantly higher sound scores in the same price range. The Sontro Soundwave may suit those prioritizing own-voice comfort over speech clarity and streaming quality, but most users would benefit from exploring higher-performing alternatives at similar or lower prices.
