Sony’s New Reon Pocket Pro Plus Wearable Air Conditioner Brings Cooler, Smarter Performance

Sony Reon Pocket Pro Plus is the latest evolution of Sony’s innovative wearable cooling device, and it promises to keep users even cooler during the increasingly intense summer months. With improved performance, smarter temperature monitoring, and a more stable design, this upgrade builds on nearly a decade of refinement and aims to bring personal climate control to the next level.

A Brief Look at Reon’s Journey

The story of Sony’s Reon cooling device began back in 2017 as an experimental concept. After successfully launching through crowdfunding in 2019, the device gradually expanded to Asian markets and eventually reached Western consumers in recent years. Now, in 2026, Sony is rolling out its newest version — the Reon Pocket Pro Plus — set to launch in the UK and Europe through Sony’s official store as well as online retailers like Amazon.

Unfortunately for American fans, Sony has yet to confirm a U.S. release, which likely means the device will remain unavailable in that market for the time being.

Not Just a Wearable Fan

It’s important to clarify that the Reon Pocket Pro Plus is not a tiny fan strapped to your neck. Instead, it uses a clever scientific technique known as the Peltier effect, which allows the device to actively cool a small metal plate using electricity. This cooled plate sits comfortably at the base of the neck, where it can deliver chilled comfort directly to one of the body’s most temperature-sensitive areas.

Because of its placement near major blood vessels, the cooling sensation spreads throughout the body more efficiently — almost like a smart, USB-C-powered ice pack. The result is a noticeably cooler feeling without the noise or bulkiness of traditional cooling solutions.

What’s New in the Pro Plus Model?

Sony has packed several meaningful upgrades into the Reon Pocket Pro Plus, building on years of user feedback and engineering improvements. The most exciting enhancements include:

• A 2°C (3.6°F) boost in cooling power, representing a 20% performance improvement
• A smarter cooling algorithm that monitors device and ambient temperatures more accurately
• A 40% increase in stability thanks to redesigned fins
• Improved comfort for different neck shapes
• Up to 10 hours of battery life on the second-highest setting
• A quieter, more refined airflow system

These improvements make the device more powerful, longer-lasting, and more reliable for everyday use during hot weather.

Smarter, More Adaptive Cooling

One of the standout features of the new Reon Pocket Pro Plus is its improved cooling algorithm. The device now responds more dynamically to temperature shifts, both on the body and in the surrounding environment. This means it can deliver more consistent cooling without unnecessarily draining its battery.

Sony has also shared heat-map demonstrations showcasing how the new model dissipates heat more effectively and maintains a stronger cooling effect for longer periods. While we haven’t tested the device firsthand, these visual demonstrations suggest a meaningful upgrade over the previous generation.

A Familiar Yet Refined Design

The overall shape and design of the Reon Pocket Pro Plus remain very similar to its predecessor, which is a good thing for fans of the original. The device discreetly rests along the back of the neck and can be worn under a shirt or any other top.

However, Sony has made the fins surrounding the cooling vent more flexible, making them better suited to fit a wider range of neck shapes. A small built-in fan still helps circulate air across the cooled metal plate, while an automatic shutdown system prevents the device from overheating during extended use.

This combination of comfort and safety makes the device suitable for daily wear, especially for commuters, outdoor workers, athletes, and travelers.

Meet the Second-Generation Pocket Tag

Sony has also introduced an upgraded accessory called the Pocket Tag (2nd gen), which comes packaged with the Pro Plus. Unlike its bulkier predecessor, this new version is smaller, lighter, and more refined.

The Pocket Tag is essentially a small environmental sensor that tracks:

• Ambient temperature
• Humidity levels
• Real-time environmental changes

This data is fed directly into the Reon’s cooling algorithm, allowing the device to fine-tune its cooling output based on actual surrounding conditions. The result is a smarter, more efficient experience that adapts to the user’s environment.

App Control and Customization

Like its predecessors, the Reon Pocket Pro Plus comes with a companion smartphone app that offers manual controls and personalized settings. Users can adjust:

• Cooling intensity
• Operating modes
• Custom temperature presets
• Battery and usage notifications

However, the device doesn’t require a smartphone to function. Users can still operate it manually, ensuring convenience for those who prefer a simpler experience.

Why Wearable Cooling Matters in 2026

With record-breaking heatwaves becoming increasingly common across Europe and other parts of the world, personal cooling devices are no longer just a novelty — they are becoming essential tools for surviving extreme temperatures. The Reon Pocket Pro Plus offers a practical solution for people who:

• Commute in hot, crowded public transportation
• Work outdoors or in poorly ventilated environments
• Travel frequently during the summer months
• Live in cities prone to rising heat levels
• Want a discreet alternative to portable fans

By focusing on a critical area of the body, the device can provide comfort without requiring users to carry around bulky accessories or rely on environmental air conditioning.

Pricing and Availability

The Sony Reon Pocket Pro Plus will be available at the following prices:

• £199 in the UK
• €220 across Europe

The device is expected to launch ahead of the 2026 summer heatwaves, giving users plenty of time to prepare for the warmer months ahead. While there’s no confirmation about a U.S. release, European buyers can already look forward to its arrival.

A Smarter Way to Stay Cool

The Sony Reon Pocket Pro Plus represents another important step in the evolution of personal cooling technology. With smarter sensors, improved performance, and a more comfortable design, it transforms the way people deal with hot weather.

While the device is not yet a global solution, its presence in markets like the UK and Europe shows that the demand for innovative cooling technology is growing fast. As climate concerns continue to rise, gadgets like the Reon Pocket Pro Plus may soon become as common as smartwatches and wireless earbuds.

For now, anyone hoping to beat the upcoming summer heat in style and comfort has a new, smarter option to consider — and Sony is once again leading the way in personal climate technology.
