[REVIEW] Sony REON POCKET PRO: Sony’s Coolest Wearable Tech Just Got Better

In a tropical country like Singapore, where humidity and heat dominate most of the year, personal cooling solutions are not just a luxury, some may even deem them as survival tools. Enter the Sony REON POCKET PRO, the latest innovation from Sony Thermo Technology, and possibly the most exciting wearable gadget we have seen so far in 2025.

Launched in Singapore on 20 May, this upgraded wearable thermo-device promises smarter, quieter, and longer-lasting cooling and heating.

We took the REON POCKET PRO out for a spin around Singapore and came away impressed. Here is everything you need to know about this futuristic personal climate control device.

What’s New in the REON POCKET PRO

While I have tested the REON POCKET PRO’s predecessor, my understanding is that it has gotten a significant upgrade, with juiced up features like:

• Dual Thermo-Modules: Unlike earlier models, this device comes with two independent Peltier cooling elements that work alternately, providing continuous cooling across a larger surface.

• 2x Cooling Area: The cooling/warming plate is now twice the size, improving comfort and efficiency.

• New Heat Dissipation Design: A stronger fan, larger heat sink, and vapour chamber work together to double the heat absorption, enhancing overall cooling power.
• Quieter Operation: It’s now 50% quieter, operating seamlessly even in silent office settings.
• Upgraded Battery: A 3,000mAh battery offers up to 34 hours of cooling at low settings, or 10 hours at COOL Level 4, perfect for all-day use outdoors.
• Physical Buttons: Users can switch modes or adjust intensity without needing a phone app. A welcome convenience.

In simple terms, this is the most powerful and user-friendly REON yet.

The REON POCKET PRO primarily targets our neck area, a spot with many blood vessels close to the surface. By cooling or heating this area, the device is said to help regulate your overall body temperature quickly and effectively.

Two of the best features for us about the REON POCKET PRO is how hands-free and low-profile it is.

Once worn under a shirt or blouse, the device becomes nearly invisible. It sits discreetly on the back of your neck, held in place by a flexible and adjustable neckband that is comfortable enough to wear all day.

This is perfect to combat Singapore’s hot and sticky weather if you need to be outdoor a lot. Unlike handheld fans or cooling scarves, the REON provides consistent, localised cooling without occupying your hands or drawing unwanted attention.

While we often focus on staying cool in Singapore, the REON POCKET PRO is also designed to heat. This makes it especially handy for Singaporeans who travel to winter destinations or work in cold indoor environments like over-airconditioned offices.

In WARM mode, the device offers adjustable heating levels. The Smart COOL⇔WARM mode even toggles between cooling and heating automatically, depending on skin temperature, surroundings, and personal preferences.

The result is dynamic, adaptive comfort.

The PRO model includes smarter sensors and algorithms to adjust performance based on:

• Body surface temperature
• Ambient temperature and humidity
• Movement such as walking vs sitting

This intelligence allows for up to 15 hours of cooling in SMART mode, far exceeding what we would expect from something so compact.

In addition, the AUTO START/STOP feature uses electrostatic sensors to reduce accidental activation, which is particularly useful when storing the device in your bag or removing it temporarily.

Here in Singapore, we tested the REON POCKET PRO on MRT rides, hawker centre lunches, and evening walks. Here is how it fared:

• During Commutes: While packed in a train during peak hour, the cooling made a noticeable difference. We stayed dry and comfortable mostly.
• Outdoor Events: For those hosting or attending outdoor events, this device can keep your body temperature manageable even when shade is limited.
• Office Use: In a business setting, the sleek grey design fits easily under collars and is quiet enough that no one notices you are wearing it.

To be clear, the REON POCKET PRO is not a substitute for a fan. It does not circulate air, nor does it cool entire spaces. Think of it as a personal climate assistant that complements your portable fan. When used together, the two can offer full-body comfort, especially for those prone to heat rash or sweating.

Also, while you do not need an app for basic use, advanced customisation like “My Mode” (a programmable sequence of heating and cooling) does require the REON Pocket app on Android or iOS.

Overall, the REON Pocket Pro is on the pricy side, but is well worth the investment if you are someone who value keeping yourself at a optimal, comfortable temperature at all time.
