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

Linner Mars
The Linner Mars is a budget-priced OTC hearing aid released in 2023, earning a B grade with a SoundScore of 3.2/5 in our lab testing. At $399, it falls in the lower price tier of the OTC category but ranks #55 of 65 OTC devices tested, placing it in the bottom 17% of its category. This visible-in-ear device presents a mixed performance profile with notable strengths and significant weaknesses. Music streaming is a standout feature, scoring an excellent 4.6/5—a full 2.68 points above the category average. Feedback handling is also excellent at 5.0/5, meaning users can expect stable performance without whistling during normal use. However, speech clarity presents challenges. Speech in quiet scores a low 1.9/5, falling 0.85 points below the category average. Speech in noise performance is particularly limited at 1.0/5, sitting 0.46 points below average. Own-voice comfort also scores low at 1.0/5, which is 1.51 points below the category average—users may notice their own voice sounding unnatural or boomy. The Linner Mars may suit budget-conscious consumers who prioritize music and media streaming over speech understanding in challenging environments. However, buyers seeking better speech performance should consider alternatives like the Elehear Beyond or Apple AirPods Pro 2, which offer stronger overall sound scores in the same price range.

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.
