Behind the Ear

The Signia Pure Charge&Go AX hearing aids are the smallest behind-the-ear devices on the market and amazingly hold the longest-lasting battery at nearly 40 hours per charge. The AX is most known for limiting background noise by using motion detection to gather information about your surroundings as you move from one space to the next. The hearing aids automatically sense when you start walking or sit down and make intelligent decisions about where to focus.

Signia Pure Charge&Go 7AX is the top technology level available, and it comes with a complete set of sound processing features, including motion detection, speech focus, and 48 channels of customization. If you regularly travel or spend time in groups, this top-end level will probably be worth the additional cost.

The breakdown

Signia Charge&Go hearing aids are comparably priced to the other top-of-the-line products like Oticon More and ReSound One. So what makes this hearing aid different?

Signia AX is currently the smallest behind-the-ear hearing aid on the market and offers the longest battery life at 36+ hours per charge. Signia has also set itself apart by doubling down on motion detection to adjust programs based on whether you are stationary or moving. Signia offers CROS functionality for people with single-sided deafness.

The tech inside

Augmented Xperience hearing aids use two processors to better differentiate speech and noise sounds. This extra processing power allows Signia to offer more motion detection to gather information about your surroundings as you move from one space to the next. The hearing aids automatically sense when you start walking or sit down and make intelligent decisions about where to focus. Signia Augmented Experience also gets top marks for the Signia Assistant feature in their app. The Signia assistant asks you simply worded questions about your current environment and preferences and adjusts your program based on your responses.

Getting up close

Signia Charge&Go AX hearing aids sit behind the ear and offer simple-to-use buttons for volume control and mode changes. These are the smallest behind-the-ear hearing aids on the market. 

Signia AX comes in 10 colors, including black, grey, beige and rosegold.

Overall notes:

Signia Charge&Go AX is a hearing aid for someone on the go. It's the smallest, has the most extended battery life, and offers best-in-class motion-based adjustments. The only real drawback to this device is that it doesn't yet offer full hands-free phone calls.
