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 ($799) that earns a B grade with a SoundScore of 3.8/5 in our lab testing, ranking #28 of 65 devices in the OTC category. This visible-in-ear device delivers strong speech-in-quiet performance, scoring 4.2/5—a full 1.36 points above the category average. Music streaming is another highlight at 3.8/5, nearly 1.9 points above average, making it a solid choice for users who value audio quality beyond speech. Speech-in-noise performance scores 2.1/5, which is above the category average by 0.62 points but remains mixed in absolute terms for challenging listening environments. The most significant limitation is own-voice comfort, scoring just 0.3/5—well below the category average of 2.51/5. Users sensitive to how their own voice sounds while wearing hearing aids should consider this trade-off carefully. Feedback handling is excellent at 4.7/5, meaning wearers can expect stable performance without whistling or squealing. The Jabra Enhance Plus is best suited for users who prioritize clear speech in quieter settings and enjoy streaming music or calls to their iPhone. Those frequently in noisy environments or particularly bothered by occlusion effects may want to explore alternatives. Several competitors in the same price range achieve higher overall scores, including the Sony CRE-E10 and Lexie B2 Plus.

The Sphere Infinio Ultra is best suited for users who prioritize speech understanding, particularly in noisy environments, and who are prepared to invest in premium technology. Those seeking the highest feedback stability or improved own-voice comfort may want to compare alternatives, though this device's speech performance stands out as a category leader.
