I found All Day Clear to offer easy and stable wireless connection. Their audio quality while streaming music, and during hands-free calling, was decent and comparable to other hearing aids in this price range.

The All-Day Clear app is straightforward and offers useful customization like volume control, programs, and a 3-Band EQ. It is missing more advanced features commonly found in other products like directional microphone controls and health tracking.
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 All Day Clear comfortable, even with prolonged wear times, and did not experience any retention issues.
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.
Sennheiser All Day Clear look and feel like modern prescription hearing aids in an OTC package.
Audien Atom Pro 2 has a value score of 3.6/5 based on lab performance and public display price.
Sennheiser All Day Clear has a value score of 4.6/5 based on lab performance and public display price.
I found Atom easy to use though they can be more challenging to insert and remove due to the small pull tab. Two features I really liked were the larger program buttons and easy to use portable charger.
All Day Clear are fairly easy to use receiver-in-canal style hearing aids and I did not run into any usability issues while trying them. One things worth noting is that, while the case works well, it does not have an internal battery and must be plugged in to charge.
Like many OTC products, Audien does not offer remote assistance from hearing experts, support is limited to email and phone customer support.
All Day Clear are self-fit OTC hearing aids, intended to be by you in the comforts of your home. However, Sennheiser offers an in-office option where they can be programmed by a provider like more traditional prescription devices.
