Linner Mars vs Signia Styletto AX

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.

The Signia Styletto AX is a premium prescription behind-the-ear hearing aid released in 2022, priced at $4,398.

This device demonstrates strong speech-in-quiet performance at 4.0/5, scoring 0.71 points above the category average.

Music streaming quality is solid at 3.1/5, exceeding the category average by 0.46 points—a meaningful advantage for users who frequently stream audio from their iPhone. Own-voice comfort scores a solid 3.0/5, slightly above category average. However, feedback handling at 3.9/5 falls 0.81 points below the category average of 4.71/5—solid in absolute terms but notably weaker than many prescription competitors in our testing. The Styletto AX has earned HearAdvisor's Expert's Choice Award in both 2023 and 2024. With its distinctive slim design, rechargeable batteries, and iPhone streaming capabilities, it may appeal to users prioritizing aesthetics and convenience alongside strong speech clarity in quieter environments. Those frequently in challenging noise situations or requiring maximum feedback stability may want to compare alternatives in this price tier.
