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 Max

The Olive Union Max is a behind-the-ear OTC hearing aid priced at $190, earning a B grade with a SoundScore of 3.4/5 in HearAdvisor's lab testing. This budget-friendly device ranks #41 of 65 OTC hearing aids tested. In our lab testing, the Max shows a distinctive performance profile with clear strengths and limitations. Music streaming stands out with a strong 4.0/5 score, measuring 2.08 points above the OTC category average—making it one of the better choices for audio entertainment. Feedback handling is excellent at 5.0/5, meaning the device maintains stability without whistling during typical daily activities. However, speech performance presents challenges. Speech in quiet scores a mixed 2.6/5, falling 0.21 points below the category average, while speech in noise is low at 1.0/5, measuring 0.48 points below average. Own-voice comfort also scores low at 1.6/5, sitting 0.91 points below the category average—users may notice their own voice sounds unnatural or hollow. The Olive Union Max is best suited for budget-conscious consumers who prioritize music and media streaming over demanding listening environments. Those who frequently need to follow conversations in noisy settings like restaurants or social gatherings may find the speech-in-noise limitations frustrating. For basic amplification in quieter environments with excellent streaming quality at an accessible price point, the Max offers reasonable value despite its speech performance trade-offs.
