Audien Hearing Atom vs Olive Union Air
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 our lab testing. At $89, it represents one of the most affordable entry points into amplification, though its performance reflects that positioning with a rank of #52 among 65 OTC hearing aids tested. The Atom's standout strength is its excellent feedback handling, scoring a perfect 5.0/5—above the category average by 0.46 points. This means users can expect stable amplification without the whistling that can plague some budget devices. However, speech performance is more limited: speech in quiet scores a mixed 2.6/5 (0.15 points below category average), while speech in noise drops to a low 1.0/5 (0.48 points below average). A significant limitation is the complete lack of music streaming capability, scoring 0.0/5—nearly 2 points below the already-modest category average. Own-voice comfort also falls below average at 2.1/5. These results suggest the Atom is designed purely for basic amplification rather than multimedia use. The Atom may suit buyers seeking the most affordable path to mild amplification who prioritize stability over advanced features. However, several competitors in the same price range offer substantially better performance—some scoring a full point higher. Those willing to consider alternatives may find meaningfully better speech clarity and additional capabilities without significant price increases.

Olive Union Air
The Olive Union Air is a budget-priced OTC hearing aid that earned a B grade with a SoundScore of 3.9/5 in our lab testing, placing it in the top 31% of OTC hearing aids at #21 of 65 devices tested. At $250, it represents a competitive entry point in the over-the-counter hearing aid market. In our testing, this visible-in-ear style device demonstrated notable strengths in music streaming, scoring 3.6/5—a solid result that sits 1.67 points above the OTC category average. Feedback handling was excellent at 5.0/5, meaning users should experience minimal whistling or squealing during normal use. Speech understanding in quiet environments also performed well at 3.3/5, measuring 0.46 points above the category average. The Olive Union Air does show limitations in more challenging listening situations. Speech in noise scored 1.0/5, falling 0.48 points below the category average—a common weakness among budget OTC devices that may affect conversations in restaurants or busy environments. Own-voice comfort measured 2.2/5, slightly below average, which some users may notice when speaking. This device is best suited for individuals who prioritize music and media streaming, need reliable feedback control, and primarily listen in quieter environments. Those who frequently encounter noisy social situations may want to consider devices with stronger speech-in-noise performance.
