Jabra Enhance Plus vs Sontro Soundwave
Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Jabra Enhance Plus
The Jabra Enhance Plus is a mid-priced OTC hearing aid priced at $799, earning a B grade with a SoundScore of 3.7/5 in our lab testing. This visible-in-ear device ranks #28 of 65 OTC hearing aids tested, placing it in the top 42% of its category. In our testing, the Enhance Plus demonstrated notable strengths in speech clarity and audio streaming. Speech in quiet scored a strong 4.2/5, measuring 1.36 points above the category average. Music streaming performance was equally impressive at 3.8/5, a full 1.88 points above average—making this a solid choice for users who prioritize phone audio streaming. Feedback handling was excellent at 4.7/5. However, the device has a significant weakness: own-voice comfort scored just 0.3/5, falling 2.21 points below the category average. This suggests pronounced occlusion effects that may make the user's own voice sound boomy or unnatural. Speech in noise performance was mixed at 2.1/5—above the category average by 0.62 points, but still limited in absolute terms for challenging listening environments. The Enhance Plus showed meaningful improvement with tuning, jumping from a normalized Initial Score of 3.6/5 to a Tuned Score of 4.2/5. Buyers should note that several competitors in the same price range score higher, including the Sony CRE-E10 at 4.66/5. This device is best suited for users who prioritize music streaming and speech clarity in quieter settings, and who can tolerate own-voice occlusion.

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.
