Audien Hearing Atom vs Linner Mars
Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Audien Hearing Atom
The Audien Hearing Atom is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.3/5 in HearAdvisor's lab testing. At $89, it's positioned as an entry-level option in the visible-in-ear category, ranking #52 of 65 OTC hearing aids tested. In our testing, the Atom demonstrates mixed results across key performance areas. Its standout strength is excellent feedback handling, scoring a perfect 5.0/5—0.46 points above the category average. This means users can expect stable performance without whistling or squealing during typical wear. However, speech clarity metrics fall below category averages: speech in quiet scores 2.6/5 (0.15 points below average) and speech in noise scores a low 1.0/5 (0.48 points below average), which may limit effectiveness in challenging listening environments. The Atom does not support music streaming, scoring 0.0/5 in this category—1.92 points below the OTC average. Own-voice comfort is mixed at 2.1/5, sitting 0.41 points below the category average. These limitations are notable when compared to similarly-priced alternatives like the Elehear Beyond (4.36/5) or Apple AirPods Pro 2 (4.06/5), which offer substantially stronger overall performance. This device may suit budget-conscious consumers who prioritize basic amplification and feedback-free wear over speech clarity in noise or streaming capabilities. Those seeking stronger speech performance or music features should consider higher-scoring alternatives in this price range.

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.
