It depends on whether you want Bluetooth streaming and hands-free calling — the Atom X has both and the Atom Pro 2 has neither. Lab scores also show the Atom X performing better in quiet (1.5/5 vs 0.7/5) and music streaming (3.3/5 vs 0.0/5), but neither device is strong in noise.

Quick Verdict
AI summarizedSummarized with AI assistance from our human-researched product information, in-lab testing, objective sound measurements, and expert ratings.
Both Audien models struggle with speech in noise, so this isn't a fight over hearing performance — it's whether Atom X's Bluetooth streaming, hands-free calling, and touchscreen case are worth roughly $110 more than the cheaper, wireless-free Atom Pro 2.
Atom Pro 2
Choose the Audien Atom Pro 2 if you want the lowest-cost entry into Audien's lineup and don't need Bluetooth streaming or calling — its 24-hour battery life is longer than the Atom X's, but its 0.5/5 speech-in-noise score and lack of wireless features make it a bare-bones budget pick.
Atom X
Choose the Audien Atom X if you want Bluetooth streaming and hands-free calling plus a touchscreen charging case for phone-free control, and you're willing to pay roughly $110 more for a device that still ranks weak in noise (0.3/5) but noticeably better in quiet (1.5/5 vs 0.7/5) and music streaming (3.3/5 vs 0.0/5).
What actually separates them
AI summarizedSpeech in noise performance
Lab measuredNeither device helps much in noise — Atom Pro 2 scored 0.5/5 and Atom X scored 0.3/5 in HearAdvisor lab testing, both far below the category average, so noisy environments are a weak spot for this whole lineup.
Wireless streaming and calling
SpecAtom X adds Bluetooth streaming (3.3/5 music score vs 0.0/5 for Atom Pro 2) and hands-free calling support that the Atom Pro 2 simply doesn't have, since Atom Pro 2 has no Bluetooth at all.
Battery life vs. control interface
Expert ratingAtom Pro 2 runs up to 24 hours per charge versus Atom X's 12 hours, but Atom X's touchscreen charging case gives handling a 4.5/5 rating versus 3.8/5 for Atom Pro 2's button-only setup.
Price
PriceAtom Pro 2 is the cheaper of the two by roughly $110, which matters if streaming isn't a priority.

Comfort

I did not find Atom Pro 2 to be the most comfortable OTC in-ear hearing aids. This was likely due to their larger size and not being tailored to a standard ear shape.

I found Atom X more comfortable than Atom Pro 2, though other hearing aids will likely offer you a better fit and overall comfort.
Design

The design of Atom Pro 2 falls between a custom hearing aid and wireless earbud. They are only available in a medical beige color, which is meant to match skin color, but will not suit everyone. The case does include a UV cleaning light which is a nice touch.

Bottom Line
AI summarizedThe Verdict
Neither Audien model is a strong performer in noise — both sit far below the site-wide average on that measure, so this comparison is really about which extras you're willing to pay for rather than which one "hears" better.
The Atom Pro 2 is the more basic, cheaper device with no wireless features but longer battery life, while the Atom X adds streaming, hands-free calling, and a touchscreen case at a roughly $110 premium, along with modestly better scores in quiet and music streaming.
Which is right for you?
If you have only mild hearing loss and mainly want basic amplification at the lowest price, the Atom Pro 2 covers that without extra cost. If you want your hearing aids to double as wireless earbuds for calls and music and you're comfortable paying more for that convenience, the Atom X is the better fit — just don't expect either one to meaningfully help in noisy rooms.
Before you buy
AI summarizedTest speech in noise during your return window
Both devices score well below average in noise (0.5/5 and 0.3/5), so use Audien's return window in a real restaurant or store before committing to either.
Decide if streaming justifies the $110 gap
Only the Atom X streams to iOS/Android and supports hands-free calls — if you don't need that, the Atom Pro 2 saves money without losing much in noise performance.
Check battery habits against your day
Atom Pro 2's 24-hour battery outlasts the Atom X's 12-hour rating, so frequent all-day users should factor in Atom X's shorter runtime and 3-4 hour recharge.
