Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

HearingAssist Control
The HearingAssist Control is a mid-priced OTC behind-the-ear hearing aid available at $549. In our lab testing, it earned a B grade with a SoundScore of 3.3/5, placing it in the top 77% of OTC hearing aids tested. This device demonstrates solid speech performance, scoring above the category average in both quiet and noisy environments. Speech in quiet earned a solid 3.4/5, while speech in noise scored 2.0/5—above average for the category but only mixed in absolute terms. Feedback handling is excellent at 5.0/5, meaning wearers should experience minimal whistling during normal use. The HearingAssist Control has notable limitations. Music streaming scored 0.0/5, indicating this device does not support audio streaming functionality—a significant gap compared to many competitors in this price range. Own-voice comfort scored 2.1/5, which is below the category average and may result in a hollow or boomy perception of your own voice. For shoppers considering this price tier, alternatives like the Yeasound RIC800 (4.73/5) and Sony CRE-E10 (4.66/5) offer substantially higher overall sound performance. The HearingAssist Control may suit buyers prioritizing speech clarity and feedback stability who don't need streaming capabilities, but most users would benefit from exploring higher-scoring options at similar price points.

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.
