A Wearable Air Conditioner That Targets the Neck
The Reon Pocket Pro Plus is Sony’s newest attempt to turn neck cooling technology into an everyday personal cooling device. Rather than being a simple fan, this portable AC wearable sits discreetly at the back of your neck, under your shirt, and uses active cooling to reduce how hot you feel in direct heat. Sony positions it as a solution for commuters and light activity, not high-intensity sports, where stability and airflow are harder to maintain. The device draws in warm air and expels it through an exhaust vent, while a chilled metal plate presses against your skin. By placing cooling hardware at a point with significant blood flow near the surface, the system aims to lower perceived body temperature quickly, cutting down sweating and discomfort during hot, humid days while remaining quiet enough for office or indoor use.
How the Reon Pocket Pro Plus Achieves 20% Stronger Cooling
Sony claims the Reon Pocket Pro Plus delivers 20% stronger cooling performance than the previous generation, and the engineering behind that gain is more than just a stronger fan. At its core, the wearable air conditioner uses the Peltier effect: an electrically cooled metal plate that can move heat away from your skin when current passes through it. Sony says the new model can drop the cooling plate temperature by an additional 2 degrees Celsius, translating to a noticeably colder sensation on the neck and, according to the company, an overall 2-degree Celsius reduction in body temperature. Internally, dual thermo-modules and refined control algorithms monitor both skin temperature and ambient conditions, dynamically adjusting output to avoid overcooling or thermal runaway. A small fan circulates air around the plate and helps evacuate heat through the exhaust vent, while an automatic shutdown feature protects the hardware if internal temperatures rise too high.
Redesigned Neckband and Exhaust Vents for Real-World Comfort
Cooling power is only useful if a personal cooling device stays in place and doesn’t blast hot air back at you. Sony’s latest design tackles both issues. The Reon Pocket Pro Plus now uses a flexible neckband that wraps over the shoulders and sits along the upper spine, improving grip compared with earlier versions that could shift during movement. Sony says the upgraded arms make it more secure for walking, commuting, or light activity, while remaining slim enough to hide under many shirts. The exhaust system has also been reworked. Users can extend and angle the vent so expelled hot air escapes above collars or jackets instead of getting trapped under clothing. Combined with a more discreet light grey finish intended to blend with lighter outfits, these changes focus squarely on day-long, real-world wearability rather than short, stationary use at a desk.
Smart Controls, Longer Battery, and Ambient Sensing
Beyond raw cooling, Sony is turning the Reon Pocket Pro Plus into a smarter portable AC wearable. Inside, sensors track skin temperature, while the companion app lets you set a target temperature and choose smart modes that automatically adjust output as the environment changes. For those who prefer to leave their phone in a pocket or bag, physical buttons on the device allow switching between cooling and heating modes and basic power control. Battery performance depends on mode, but Sony quotes up to 10 hours on the second-highest cooling level, and up to 15 hours when using smart cooling that varies intensity dynamically. The wearable air conditioner ships with the Reon Pocket Tag 2, a smaller clip-on sensor that measures ambient temperature and humidity. By feeding this data back to the main unit, the system can tune its cooling more precisely, minimizing both battery waste and unnecessary cold blasts.
From Niche Gadget to Practical Personal Cooling Device
The Reon Pocket line began as a niche experiment in wearable climate control, but the Pro Plus iteration shows Sony methodically addressing the barriers to everyday use. Stronger neck cooling, a claimed 2-degree Celsius body temperature reduction, quieter operation, and an improved neckband make it more viable for long commutes or office days. Adjustable exhaust vents and a more discreet profile help it fit under typical work or casual outfits, broadening its appeal beyond tech enthusiasts. Pricing signals that Sony sees this as a premium gadget: it is listed at £199 in the UK and €229 in Europe. For now, availability is limited to select markets and Sony’s online store, but the engineering direction is clear. By combining refined neck cooling technology, smarter sensing, and better ergonomics, the Reon Pocket Pro Plus moves closer to making the wearable air conditioner a practical, if still specialized, everyday accessory.
