HearingAssist Control vs Oticon Zeal
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 behind-the-ear OTC hearing aid priced at $549, earning a B grade with a SoundScore of 3.3/5 in our lab testing. This places it in the lower portion of the OTC category, ranking #51 of 65 devices tested. In our testing, the Control demonstrates notable strengths in speech performance. Speech in quiet scores 0.59 points above the category average at 3.4/5, representing solid absolute performance. Speech in noise comes in at 2.0/5—above the category average by 0.56 points, though only mixed in absolute terms. Feedback handling is excellent at 5.0/5, meaning the device remained stable without audible squealing during our standardized challenge tests. The device shows significant weaknesses in other areas. Music streaming scored 0.0/5, which is 1.92 points below the category average and indicates this device does not support or perform well with phone audio streaming. Own-voice comfort is also below average at 2.1/5 (0.41 points below category average), which may be noticeable during extended conversations. The HearingAssist Control may suit users who prioritize speech clarity over streaming functionality and who don't require premium sound quality across all use cases. However, buyers in this price range should note that several competitors—including the Yeasound RIC800 and Sony CRE-E10—deliver substantially higher overall scores. Those seeking similar speech performance at a lower cost may also consider the iHear MatriX.
Choice

Oticon Zeal
The Oticon Zeal is a premium invisible-in-ear prescription hearing aid priced at $4,798. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.7/5, placing it in the top 11% of prescription hearing aids tested and ranking #5 of 36 devices in its category. Speech performance is where the Zeal truly excels. It achieved an excellent 4.9/5 in speech-in-quiet testing, scoring 1.56 points above the category average—among the strongest results we've measured. Speech-in-noise performance is solid at 3.0/5, which is 1.08 points above the category average of 1.96/5, making it notably better than typical prescription aids in challenging listening environments. Music streaming quality scores 3.3/5, sitting 0.66 points above category average and providing solid fidelity for phone audio. However, the Zeal shows some limitations in other areas. Own-voice comfort is mixed at 2.0/5, falling 0.75 points below the category average—users sensitive to how their own voice sounds may notice this. Feedback handling, while solid in absolute terms at 3.3/5, measures 1.41 points below the category average of 4.71/5. The Zeal is best suited for users who prioritize outstanding speech clarity in both quiet and moderately noisy settings, and who value quality audio streaming. Those particularly sensitive to own-voice perception or who need maximum feedback stability may want to discuss these tradeoffs with their hearing care provider.
