Nuheara IQBuds Max vs Sontro Soundwave
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.

Sontro Soundwave
The Sontro Soundwave is a mid-priced OTC hearing aid priced at $849, earning a B grade with a SoundScore of 3.1/5 in HearAdvisor's lab testing. This behind-the-ear device uses disposable batteries and ranks #61 of 65 OTC hearing aids tested, placing it in the top 92% of its category. In our lab testing, the Soundwave shows a notable strength in own-voice comfort, scoring 3.6/5—a solid result that sits 1.09 points above the category average. This suggests users may experience less of the "talking in a barrel" sensation that can occur with some hearing aids. However, the device faces challenges in other key areas. Speech in quiet scores 2.7/5 (mixed, 0.12 points below average), while speech in noise registers at 1.2/5 (low, 0.28 points below average), indicating potential difficulty in challenging listening environments. The most significant limitations appear in music streaming and feedback handling. Music streaming scores 0.0/5, falling 1.92 points below the category average—a notable weakness for users who value audio entertainment. Feedback handling scores 2.5/5, which is 2.04 points below the category average of 4.54/5, suggesting the device may be more prone to whistling issues. At this price point, competitors offer substantially stronger performance. Devices like the Sony CRE-E10 and Lexie B2 Plus deliver significantly higher sound scores in the same price range. The Sontro Soundwave may suit those prioritizing own-voice comfort over speech clarity and streaming quality, but most users would benefit from exploring higher-performing alternatives at similar or lower prices.
