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.
Choice

ReSound OMNIA miniRIE
The ReSound OMNIA miniRIE is a premium behind-the-ear prescription hearing aid released in 2022, priced at $4,764. In our lab testing, it earned an A grade with a SoundScore of 4.0/5, ranking #24 of 36 devices in the Prescription Hearing Aid category. This device demonstrates solid performance in speech clarity for quiet environments, scoring 3.7/5—0.34 points above the category average. However, speech understanding in noisy situations is a notable weakness, with a score of just 1.0/5, falling 0.96 points below the category average. This contrast suggests the OMNIA miniRIE performs best for users who primarily need support in calmer listening environments rather than challenging acoustic situations like busy restaurants or crowded gatherings. Feedback handling is strong at 4.1/5 in absolute terms, though it sits 0.61 points below the category average of 4.71/5. Own-voice comfort scores 2.9/5, slightly above average but mixed in absolute terms. Music streaming performance is similarly positioned at 2.7/5—essentially at the category average. The OMNIA miniRIE features rechargeable batteries, iPhone and Android streaming capability, and hands-free functionality. It has received the Expert's Choice Award in both 2023 and 2024. At this premium price point, buyers should be aware that several same-price competitors like the Phonak Sphere Infinio and Oticon Intent offer higher overall scores in our testing. This device may suit users prioritizing quiet-environment speech clarity and brand-specific features over maximum performance in noise.
