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 3.3/5 in our lab testing. Priced at $499, this visible-in-ear device from 2021 ranks #46 of 65 OTC hearing aids tested, placing it in the top 69% of its category. The standout feature of the IQBuds Max is its exceptional music streaming performance, scoring 4.3/5—a strong result that sits 2.38 points above the category average. For users who prioritize audio entertainment alongside hearing assistance, this device delivers notably better streaming fidelity than most OTC alternatives. However, speech performance presents a mixed picture. Speech in quiet scores 2.0/5, falling 0.78 points below the category average. Speech in noise is essentially at par with competitors at 1.5/5, which is above average for the category but low in absolute terms. Own voice comfort also trails the category average by 0.31 points with a score of 2.2/5. Feedback handling scores a solid 3.4/5 in absolute terms, though this falls 1.14 points below the category average. The IQBuds Max is best suited for users who value music and audio streaming quality over speech clarity, particularly those seeking an affordable entry point into amplification. Competing devices in this price range—including the Elehear Beyond (4.34/5) and Apple AirPods Pro 2 (4.04/5)—offer stronger overall sound performance for similar investment.

Phonak Sphere Infinio
The Phonak Sphere Infinio is a premium behind-the-ear prescription hearing aid released in 2024, priced at $4,898. In our lab testing, it earned an A grade with a SoundScore of 5.0/5, placing it at #2 among 39 prescription hearing aids tested—within the top 3% of its category. The standout performance comes in speech clarity. Speech in noise scores an excellent 4.7/5, a remarkable 2.59 points above the category average of 2.11/5. Speech in quiet also impresses at 4.5/5, sitting 1.07 points above average. For anyone who struggles to follow conversations in restaurants, gatherings, or busy environments, this device delivers measurably superior intelligibility compared to most alternatives we've tested. Music streaming quality is strong at 4.0/5, exceeding the category average by 1.24 points—a meaningful advantage for users who value audio fidelity when streaming from phones. However, own-voice comfort is mixed at 2.3/5, falling 0.40 points below the category average, which may affect how natural your own speech sounds. Feedback handling, while solid in absolute terms at 3.6/5, sits 1.12 points below the category average of 4.72/5. The Sphere Infinio is best suited for users prioritizing exceptional speech understanding, particularly in challenging noise environments, and who are willing to invest at the premium tier. Those especially sensitive to own-voice quality or requiring maximum feedback stability may want to compare alternatives like the similarly-priced Oticon Intent or the lower-priced Phonak Audéo EON Sphere.
