JVC EH-Z1500
The JVC EH-Z1500 is a mid-priced OTC hearing aid priced at $600, earning an A grade with a SoundScore of 4.0/5 in our lab testing. This behind-the-ear device ranks #19 among 65 OTC hearing aids tested, placing it in the top 28% of its category. Speech clarity is where this device truly excels. In quiet environments, it scores an excellent 4.6/5, performing 1.77 points above the category average. Speech in noise measures 2.6/5—above the category average by 1.09 points, though only mixed in absolute terms. For conversations in calm settings, the EH-Z1500 delivers strong performance that outpaces most OTC competitors. However, this device has notable limitations. Music streaming is not supported, scoring 0.0/5 and falling 1.92 points below the category average. Feedback handling scores a solid 3.8/5 in absolute terms, though this sits 0.74 points below the category average of 4.54/5. Own-voice comfort is mixed at 2.4/5, roughly in line with category norms. The EH-Z1500 uses disposable batteries and a tulip dome coupling. For those prioritizing speech intelligibility in quieter environments over streaming capabilities, this device offers solid value. However, buyers who want music streaming or need strong noise performance should consider alternatives like the Sony CRE-E10 or Lexie B2 Plus in this 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.
