JabraSoundScore 3.7Grade B

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.

Olive Union Air

The Olive Union Air is a budget-priced OTC hearing aid that earned a B grade with a SoundScore of 3.9/5 in our lab testing, placing it in the top 31% of OTC hearing aids at #21 of 65 devices tested. At $250, it represents a competitive entry point in the over-the-counter hearing aid market. In our testing, this visible-in-ear style device demonstrated notable strengths in music streaming, scoring 3.6/5—a solid result that sits 1.67 points above the OTC category average. Feedback handling was excellent at 5.0/5, meaning users should experience minimal whistling or squealing during normal use. Speech understanding in quiet environments also performed well at 3.3/5, measuring 0.46 points above the category average. The Olive Union Air does show limitations in more challenging listening situations. Speech in noise scored 1.0/5, falling 0.48 points below the category average—a common weakness among budget OTC devices that may affect conversations in restaurants or busy environments. Own-voice comfort measured 2.2/5, slightly below average, which some users may notice when speaking. This device is best suited for individuals who prioritize music and media streaming, need reliable feedback control, and primarily listen in quieter environments. Those who frequently encounter noisy social situations may want to consider devices with stronger speech-in-noise performance.
