Sony's Wearable AC Gets 20% Cooler for Summer 2026

Imagine wearing your own personal air conditioner that fits around your neck like a necklace and keeps you cool all day long.

Sony just made that technology even better. The company's Reon Pocket Pro Plus launches in the UK and Europe this spring, bringing a significant boost to wearable cooling tech that's been in development since 2017.

This isn't a simple fan. The device uses something called the Peltier effect, where an electrically cooled metal plate sits at the base of your neck. That spot is perfect for cooling because your circulatory system naturally distributes the lower temperature throughout your body, like wearing a tiny ice pack that never melts.

The new model delivers 3.6 degrees Fahrenheit more cooling than its predecessor, a 20% jump in performance. Sony also improved the temperature monitoring system so the device can better adjust to changing conditions around you.

Despite the power boost, battery life remains impressive. The Reon runs for up to 10 hours on its second-highest cooling setting, plenty for a full workday outdoors or a long summer event.

Sony redesigned the neck fins to make the device 40% more stable, so it stays in place while you move. A quiet fan circulates air across the cooling area, and automatic shutdown protects against overheating.

Why This Inspires

Climate change means hotter summers are becoming the norm across Europe and beyond. Personal cooling technology like the Reon offers a practical solution that doesn't require cranking up energy-hungry air conditioning systems.

The device could be especially helpful for outdoor workers, athletes, or anyone who spends time in the heat. At £199 in the UK and €220 in Europe, it's priced competitively with other premium wearables.

Sony included a new Pocket Tag accessory that monitors humidity and temperature to help the Reon fine-tune its cooling. You can control everything through a smartphone app or use the device standalone.

After nearly ten years of refinement, Sony has turned a novel concept into genuine innovation that could help millions stay comfortable and safe in rising temperatures.
