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

GoHearing Ultra
The GoHearing Ultra is a budget-priced OTC behind-the-ear hearing aid that earned a B grade with a SoundScore of 3.1/5 in our lab testing. At $499, it sits in the most affordable tier of OTC devices, though its overall performance ranks 58th out of 65 OTC hearing aids tested. This device shows a distinctive performance profile with notable strengths in specific areas. Feedback handling earned an excellent 5.0/5, scoring 0.46 points above the category average—meaning users are unlikely to experience whistling or squealing during typical use. Music streaming also performed well at 3.6/5, a solid score that sits 1.68 points above the OTC average of 1.92/5, making it a reasonable choice for those who prioritize phone audio streaming. However, the GoHearing Ultra struggles in core speech understanding metrics. Speech in quiet scored just 1.0/5, falling 1.79 points below the category average, while speech in noise also scored 1.0/5, sitting 0.48 points below average. Own-voice comfort measured 1.9/5, which is 0.61 points below the typical OTC device. These low speech scores significantly limit the device's utility for its primary purpose of improving conversation clarity. Consumers seeking better overall value in this price range may want to consider alternatives like the Elehear Beyond (4.36/5) or Apple AirPods Pro 2 (4.06/5), which deliver substantially stronger speech performance. The GoHearing Ultra may suit buyers who prioritize streaming audio and feedback-free wear over speech enhancement, but those seeking meaningful speech benefit should explore higher-performing options.
Choice

Phonak Audéo EON Sphere
The Phonak Audéo EON Sphere is a premium behind-the-ear prescription hearing aid priced at $4,398. In HearAdvisor's lab testing, it earned a SoundScore of 5.0/5 and an A grade, placing it among the top performers in the prescription hearing aid category. Speech performance stands out as this device's greatest strength. Speech in noise scored an excellent 4.5/5, a full 2.53 points above the category average of 1.96/5—a substantial margin that makes this one of the strongest performers in challenging listening environments. Speech in quiet also performed well at 4.3/5, nearly a full point above the category average. These results suggest the Audéo EON Sphere may be particularly well-suited for users who frequently encounter noisy social settings or group conversations. Music streaming delivered a solid 3.7/5, more than a point above the category average of 2.64/5, indicating above-average audio fidelity for phone-streamed content. Own-voice comfort scored 2.8/5, which sits just above the category average but reflects mixed absolute performance—users sensitive to occlusion effects should discuss this with their hearing care provider. Feedback handling scored an excellent 4.6/5 in absolute terms, though it lands slightly below the category average of 4.71/5. The Audéo EON Sphere represents Phonak's latest premium technology and delivers strong results across most metrics in our standardized testing. It's best suited for users prioritizing speech clarity in difficult listening situations who are prepared for the premium price point.
