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

Nuheara IQBuds Max
The Nuheara IQBuds Max is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.4/5 in our lab testing. At $499, it sits in the affordable tier of the OTC category, ranking #46 of 65 devices tested. The standout performance area for the IQBuds Max is music streaming, which scores a strong 4.3/5—significantly above the category average by 2.38 points. This makes it one of the better choices in the OTC space for users who prioritize audio entertainment alongside hearing assistance. However, speech performance presents a mixed picture: speech in quiet scores 2.0/5, falling 0.78 points below the category average, while speech in noise scores a low 1.5/5, though this is essentially at the category average. Own-voice comfort is mixed at 2.2/5, sitting slightly below the category average. Feedback handling scores a solid 3.4/5 in absolute terms, though this is 1.14 points below the category average of 4.54/5. The device features rechargeable batteries and supports both iPhone and Android streaming with hands-free capability. The IQBuds Max is best suited for users who want an affordable entry into amplification with strong music streaming performance, but who have modest expectations for speech clarity improvement. Those prioritizing speech understanding may want to consider higher-ranked alternatives in the same price range, such as the Elehear Beyond or Apple AirPods Pro 2.
Choice

Phonak Sphere Infinio Ultra
The Phonak Sphere Infinio Ultra is a premium behind-the-ear prescription hearing aid priced at $4,898. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.9/5, placing it in the top 3% of the 36 prescription hearing aids tested and ranking #2 in its category. This device delivers exceptional speech performance in our testing. Speech in noise scored an excellent 4.5/5, a remarkable 2.55 points above the category average of 1.96/5—one of the largest margins we've measured in this critical metric. Speech in quiet also performed strongly at 4.3/5, exceeding the category average by 1.00 point. These results suggest the Sphere Infinio Ultra prioritizes speech clarity across challenging listening environments. Music streaming quality is solid at 3.3/5, sitting 0.66 points above the category average. Own voice comfort scored 2.8/5, which is above the category average but remains mixed in absolute terms—listeners sensitive to occlusion may notice this limitation. Feedback handling measured 4.2/5, which is strong in absolute terms though 0.51 points below the category average of 4.71/5. The Sphere Infinio Ultra is best suited for users who prioritize speech understanding, particularly in noisy environments, and who are prepared to invest in premium technology. Those seeking the highest feedback stability or improved own-voice comfort may want to compare alternatives, though this device's speech performance stands out as a category leader.
