Sony's Revolutionary Cooling Neck Device: First Impressions and Review (2026)

In a world where extreme weather events are becoming increasingly common, the quest for innovative cooling solutions has never been more relevant. Sony's Reon Pocket Pro Plus, a wearable heating and cooling device, is a prime example of this trend. Personally, I find it fascinating how technology is evolving to address our most basic needs, and this device is a testament to that.

The Rise of Personal Cooling Devices

With record-breaking heat waves sweeping across the US, it's no surprise that personal cooling devices are gaining traction. Major players in the air care industry, like Dyson, Shark, and Blueair, have already jumped on the bandwagon with their handheld fans. Now, Sony Electronics is joining the fray with its Reon Pocket Pro Plus, a device that has been available in Japan since 2019 but is now making its way to the US market.

A Discreet and Adaptable Solution

Weighing just 8.7 ounces, the Reon Pocket Pro Plus is designed to be worn around the neck, discreetly tucked under clothing. Its stainless steel plate, which comes into contact with the skin, allows users to manually adjust the temperature range from 41 to 104 degrees Fahrenheit. But what makes this device truly unique is its smart mode. With multiple temperature and humidity sensors, the device's algorithm automatically adjusts the plate's temperature to the wearer's preference, ensuring a comfortable and personalized experience.

The Technology Behind the Cool

The device's plate utilizes a Peltier element, a semiconductor module that can cool on one side and heat on the other when an electric current is applied. To maximize cooling performance, the device employs a high-volume fan, a vapor chamber, and heat-dissipation fins to release the internal heat generated on the opposite side of the plate. This technology is impressive, and I was surprised by how quickly the device could adjust its temperature, providing an immediate cooling effect on the upper back.

Comfort and Convenience

The Reon Pocket Pro Plus comes with an adjustable and bendable neckband, ensuring a comfortable fit. There are also extension tips that can be removed to adjust the length. While the device is lightweight and comfortable, I would have preferred a softer material covering the plastic neckband for added comfort. Additionally, the device works best when the wearer is stationary or not moving their upper back excessively, which makes sense given its intended use during walking or hiking.

Silence is Golden

One of the standout features of the Reon Pocket Pro Plus is its silent operation. During my testing, I barely noticed any noise, which is a huge advantage for a discreet cooling device. Battery life is also impressive, with up to 15 hours on the cool setting in smart mode. This is significantly longer than the Dyson HushJet Mini Cool handheld fan, which offers up to 6 hours of battery life on low speed.

The Price Tag

The main drawback of the Reon Pocket Pro Plus is its price. At $260, it is significantly more expensive than other handheld fans on the market, such as the Shark ChillPill, which retails for $150. While the Reon Pocket Pro Plus offers unique features like silent operation and heating capabilities, the price may be a deal-breaker for many consumers.

Final Thoughts

Sony's Reon Pocket Pro Plus is an innovative and discreet cooling solution, offering a personalized and adaptable experience. While it excels in silence and battery life, the price tag may be a deterrent for some. If you're looking for a quiet and low-profile cooling device and have the budget for it, the Reon Pocket Pro Plus is a cool investment. However, for those on a tighter budget, handheld fans like the Blueair AlwaysCool or the Shark ChillPill are more affordable alternatives.
