Hear.com Horizon Go IX
The Hear.com Horizon Go IX is a premium prescription behind-the-ear hearing aid released in 2024, priced at $6,500. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.4/5, ranking #19 among 39 prescription hearing aids tested. Speech performance is a clear strength for the Horizon Go IX. It scores 4.0/5 in speech-in-quiet conditions—0.64 points above the category average—delivering strong audibility in conversational settings. Speech-in-noise performance also exceeds the category average by 0.46 points, though at 2.6/5 the absolute score remains mixed, meaning challenging listening environments may still pose difficulties. Own-voice comfort is the device's most notable weakness, scoring just 1.8/5—a low result that falls 0.90 points below the category average. Users sensitive to how their own voice sounds may find this limiting. Feedback handling scores 4.4/5, which is strong in absolute terms, though slightly below the category average of 4.72/5. Music streaming performance is essentially average at 2.7/5. At this price point, shoppers face stiff competition. Several alternatives in the same premium tier—including the Phonak Sphere Infinio, Oticon Intent, and Widex Allure RIC 440—deliver higher overall scores. Devices like the Rexton Reach R-Li T80 at Costco offer comparable or better sound performance at lower prices. The Horizon Go IX is best suited for users who prioritize speech clarity and have access to this product through hear.com's network, but those flexible on brand should compare alternatives before committing.

MDHearing Volt
The MDHearing Volt is a budget-priced prescription hearing aid released in 2020, earning a B grade with a SoundScore of 3.0/5 in our lab testing. At $397, it sits in the lowest price tier for prescription devices, ranking #34 of 39 in its category. In our testing, the Volt showed a mixed performance profile with one standout strength: feedback handling scored an excellent 5.0/5, which is 0.28 points above the category average. This means users can expect minimal whistling or squealing during typical wear. However, speech performance was limited, with speech in quiet scoring 1.8/5 (1.65 points below average) and speech in noise at 1.0/5 (1.11 points below average). Own voice comfort was mixed at 2.6/5, roughly matching the category average. Music streaming capability was not functional in our testing, scoring 0.0/5—a significant limitation for users who want to stream audio from their phone. This is 2.76 points below the prescription hearing aid category average. The Volt may appeal to budget-conscious consumers who prioritize basic amplification and feedback-free wear over advanced speech enhancement or streaming features. Those seeking stronger speech performance in the same price range may want to consider alternatives like the RxEars Rxi, which scored 4.07/5 in our testing. The Volt's rechargeable battery and behind-the-ear design offer practical convenience, but its core sound performance reflects its entry-level positioning.
