Sony’s new wearable cooler beats rising summer heat by cooling the body directly through a neck-worn device, with advanced thermoelectric technology and smart sensors to adjust temperature, it improves people’s comfort.

Summer heat is one of the hardest situations to bear or ignore. Walking outside can feel like stepping into an oven, especially during peak afternoon hours. Now, Sony is offering a different kind of solution, not bigger fans or stronger air conditioners but a wearable device you can slip under your shirt collar.

Sony’s new wearable cooler Reon Pocket Pro Plus is trying to change how people deal with rising summer temperatures. Instead of relying on air conditioners or portable fans, this device helps cooling your body directly through a small device you wear under your clothes

How does this new wearable cooler work

What if your body could feel cooler even when the air around you isn’t? That’s the idea behind Sony’s latest wearable device, the Reon Pocket Pro Plus. Unlike typical cooling gadgets, this one sits under your shirt collar and works like a personal temperature controller for your body.

It uses a scientific method called the Peltier effect. In simple terms, an electric current cools a metal plate that touches the back of your neck. Since the neck connects closely to blood circulation, the cooling effect spreads quickly, making you feel relief faster than a small handheld fan.

So what’s new in the Pro Plus version

Sony says this model is its most powerful version yet, designed specifically for hotter summers and longer use outdoors.

Here’s what stands out:

  • Cooling performance improved by up to 20% compared to earlier models

  • Surface temperature reduced by about 2°C for stronger relief

  • Two thermal modules that switch intensity for steady cooling

  • Built-in fan to spread cool air more evenly behind the neck

  • Smart sensors that adjust temperature based on environment and activity

  • “Smart Cool” and “Smart Warm” modes for changing weather conditions

In short, this new gadget is not just about cooling. It tries to respond to your surroundings automatically, which means it can help during winters as well.

Can something so small really handle summer heat

Sony believes it can, especially for daily routines like commuting, walking or spending time outdoors in light activity. The device is designed to sit more securely than earlier versions, using a redesigned neckband structure for better stability.

It also runs for a long time:

  • Up to 15 hours in Smart Cool mode

  • Around 10 hours in stronger cooling settings

The device can be controlled through physical buttons or a mobile app, giving users flexibility without needing constant adjustments.

Designed for comfort, not extreme sports

The Reon Pocket Pro Plus is built to stay discreet under clothing, especially lighter outfits. However, it’s not meant for heavy physical activity like running or intense workouts. It works best when movement is moderate and steady.

Sony has also improved airflow direction, helping hot air move away from the body more effectively, even with collars or layered clothing.

A glimpse into personal climate control

As Business Fortune observes, Reon Pocket Pro Plus shows a clear change in how people may handle rising summer heat in the future. Instead of cooling whole rooms, the focus is now shifting to cooling the person directly.

Right now, the device is being launched in parts of Europe and the UK, with no confirmed release in other regions yet. But as summers around the world get hotter, wearable cooling devices like this could become more common. What once felt unusual may soon turn into a normal part of everyday summer clothing.
