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

Orka Two
The Orka Two is a behind-the-ear prescription hearing aid priced at $1,899, earning an A grade with a SoundScore of 4.0/5 in our lab testing. This places it in the top 67% of the 36 prescription hearing aids we've evaluated, ranking #25 in its category. In our testing, the Orka Two shows a mixed performance profile with clear strengths and weaknesses. Music streaming stands out at 3.3/5, measuring 0.66 points above the category average—a solid result for users who prioritize phone audio quality. Own-voice comfort also performs well at 3.2/5, sitting 0.45 points above average, which may contribute to a more natural listening experience. Feedback handling is excellent at 5.0/5, among the best we've measured. However, speech-in-noise performance is a notable limitation. At 1.4/5, it falls 0.56 points below the category average—a low absolute score that may affect understanding in challenging listening environments like restaurants or group conversations. Speech in quiet fares better at 3.7/5, measuring 0.40 points above average. The Orka Two may suit users who prioritize streaming quality, own-voice comfort, and stability over speech-in-noise performance. Those frequently in noisy environments should note that competitors in this price range, such as the Rexton Reach R-Li T80 at Costco (4.58/5), deliver stronger overall scores. Budget-conscious shoppers might also consider lower-priced alternatives like the Sony CRE-C10, which scored 4.19/5 in our testing.
