The over-the-counter (OTC) hearing aid market continues to evolve in 2025, with two standout models leading the conversation: CHOSGO SmartR and Audien Atom Pro 2.
Both are ultra-compact rechargeable hearing aids designed for users with mild to moderate hearing loss, offering affordable alternatives to traditional prescription devices.
But how do they really compare in terms of performance, comfort, and value? Let’s break it down.

1. Brand Overview

Audien Hearing, established in 2016, built its reputation on affordability—offering basic rechargeable hearing aids for under $100. The Atom Pro 2, one of its latest models, introduces a few premium touches like UV sanitization and adaptive hearing modes, yet remains focused on simplicity and budget pricing.

CHOSGO, on the other hand, represents the new generation of AI-enhanced OTC hearing aids. The SmartR model combines compact design, intelligent sound processing, and multiple environment programs in a truly invisible form factor—targeting users who value both performance and discretion.

While Audien’s strength lies in price, CHOSGO aims to deliver a more refined hearing experience through technology and comfort.

💡 Verdict:
Audien introduces convenience features like UV cleaning, but CHOSGO wins in audio precision and adaptive performance, offering better clarity in different environments.

4. Sound Quality and Comfort

Audien Atom Pro 2 provides decent sound amplification for everyday conversations but can struggle in noisy or dynamic settings due to limited adaptive processing.

CHOSGO SmartR, meanwhile, delivers natural, crisp sound reproduction enhanced by AI noise control and multi-environment programs.
Its ultra-small, canal-invisible design makes it one of the most discreet OTC hearing aids available—ideal for users who want comfort and subtlety without sacrificing sound quality.

Winner: CHOSGO SmartR — clearer sound in variable environments and a more ergonomic, invisible fit.

5. Battery Life and Charging

Both devices feature rechargeable batteries and portable charging cases.
However, CHOSGO SmartR advertises a longer-lasting power reserve and a fast-charging portable case, making it more suitable for users who prefer multi-day use without frequent recharging.

Audien’s UV-cleaning case adds hygiene convenience, but it slightly compromises compactness and total charge cycles.

Winner: CHOSGO SmartR — better endurance and portability.

CHOSGO SmartR is best for:

  • Users with mild to moderate hearing loss who want natural sound and adaptive AI processing
