A New Phase for Wearable Cooling Technology
Wearable cooling technology has often felt like a niche experiment, but Sony’s Reon Pocket series has quietly evolved into a serious category. The new Reon Pocket Pro Plus is the third major iteration of Sony’s neck cooling device, a personal air conditioner designed to sit discreetly under clothing at the base of the neck. Instead of simply blowing air, it uses a thermoelectric system to cool a metal plate that rests against the skin, helping reduce sweat and heat fatigue during everyday activities such as commuting or walking. Sony now positions the Reon Pocket Pro Plus as a premium wearable cooling device, reasserting its presence in this space just as competition from other consumer electronics brands intensifies. By emphasizing stronger cooling performance, smarter temperature control, and refined ergonomics, Sony aims to shift the product from novelty gadget toward a genuinely practical neck cooling device for hot-weather comfort.
How the Reon Pocket Pro Plus Cools 20% Better
At the heart of the Reon Pocket Pro Plus is an electrically cooled metal plate that leverages the Peltier effect to draw heat away from the skin. Sony says this model delivers a 20% improvement in cooling performance over the previous generation, translating into a 2-degree Celsius drop in plate temperature. That seemingly small difference can feel significant when applied directly to a highly vascular area at the back of the neck, where blood flow close to the surface helps spread the cooling effect through the body. Internally, dual thermo-modules and temperature sensors track both skin and ambient conditions, while refined control algorithms adjust output in real time. Airflow is assisted by a small fan that moves warm air away from the device, contributing to more stable cooling over longer periods. The result is a more responsive personal air conditioner that feels colder, faster, and more consistently than older Reon Pocket models.
Redesigned Neckband and Adjustable Exhaust for Everyday Comfort
Beyond raw cooling power, the Reon Pocket Pro Plus focuses heavily on comfort and stability—two weaknesses of earlier designs. The updated neckband now drapes over the shoulders and down the spine, using flexible arms that grip more securely while remaining comfortable under clothing. This reduces the tendency of the unit to shift when you walk, bend, or engage in what Sony calls light activity, making it more suitable for daily commuting than for intense sports. The exhaust vent has also been reworked: it can be extended and angled, directing hot air away from the body and out from under high collars or jackets. Combined with a more discreet light grey finish meant to blend with light-colored shirts, these tweaks make the device easier to hide and less intrusive. Together, the new fit and airflow design address practical pain points that limited older Reon Pocket devices in real-world use.
Battery Life, Smart Controls, and Real-World Use Cases
Battery endurance is a crucial metric for any neck cooling device, and Sony claims the Reon Pocket Pro Plus can run for up to 10 hours on the second-highest cooling setting and as long as 15 hours in its smart cooling mode. Quiet operation means it can be worn in offices or indoor environments without drawing attention. Users can control the unit via physical buttons to switch between heating and cooling or adjust modes, or they can rely on the companion app to set target temperatures and automate adjustments based on environmental changes. Sony bundles the Reon Pocket Tag 2, a small wearable sensing device that clips to a bag or belt to monitor ambient temperature and humidity, feeding data back for more precise regulation. In practice, this positions the Reon Pocket Pro Plus as a flexible personal air conditioner for commuters, office workers, and anyone needing sustained relief from heat rather than just a quick blast of cool air.
Positioning Against Rivals in the Wearable Cooling Market
Sony’s renewed focus on the Reon Pocket Pro Plus signals its intent to stay competitive as wearable cooling technology becomes more mainstream and premium players enter the market. The device combines stronger cooling, a more secure neckband, and adjustable vents into a package that aims to be both more comfortable and more effective than earlier Reon Pocket models. Pricing in Europe and the UK—€229 and £199 respectively—confirms its positioning as a premium gadget rather than an impulse buy. However, Sony counters that with tangible functional gains: better thermal performance, longer runtime, smarter sensor-driven control, and bundled ambient sensing via the Tag 2 accessory. For consumers comparing options, the Reon Pocket Pro Plus offers a blend of engineering refinement and real-world usability that helps distinguish it from simpler fan-based solutions, reinforcing Sony’s role as a serious contender in the evolving market for personal air conditioners and neck cooling devices.
