A Personal Cooling Wearable Built Around the Neck
Sony’s Reon Pocket Pro Plus is the new flagship in its personal cooling wearable lineup, designed as a compact neck cooling device that sits at the back of the neck under a shirt collar. Instead of acting like a simple fan, it uses a cooled metal plate to directly regulate skin temperature at a point where blood vessels run close to the surface, amplifying the sensation of cooling. This wearable air conditioner combines a Peltier-based thermo module with an integrated fan to circulate air around the plate and collar area. By targeting a small but thermally sensitive region, the device aims to deliver noticeable thermal comfort technology without needing to chill the entire body. Sony’s approach reflects a broader shift away from room-scale air conditioning toward focused, on-body cooling that can adapt to commuting, office work, and outdoor movement.
Stronger Cooling Performance and Smarter Thermal Control
The Reon Pocket Pro Plus focuses heavily on boosting cooling performance while keeping operation stable over time. Sony claims up to a 20% improvement versus the previous flagship, supported by a revised high-efficiency thermal design and a new cooling algorithm. In SMART COOL mode, the device can further lower the body surface temperature at the contact point by up to an additional 2°C after sustained use in hot conditions, making the cooling feel more immediate and durable. The Peltier module actively responds to temperature changes on the metal plate and in the surrounding air, automatically adjusting output to maintain comfort and reduce abrupt swings from cold to warm. An automatic shutdown feature is also built in to protect the hardware from overheating, helping the system stay reliable during extended sessions while still delivering robust neck cooling.
Redesigned Neckband for Secure, Long-Term Wear
To make this neck cooling device more practical for daily life, Sony has overhauled the neckband with what it calls an Adaptive Hold Design. On the Reon Pocket Pro Plus, the flexible mechanical tubing now has a larger diameter and delivers roughly 40% more holding force than the older neckband design. The aim is to keep the cooled metal plate in consistent contact with the neck—even while walking or performing light activity—without creating pressure points. The redesigned band tracks movement more smoothly and reduces slippage, supporting longer wear times and better thermal performance, since cooling efficiency depends heavily on a stable fit. Sony has also revamped the air vent cover, allowing users to extend, retract, and change the angle of the exhaust. This adjustability helps manage airflow around different collar heights, fabrics, and neck shapes, which can otherwise trap heat and limit the effectiveness of the wearable air conditioner.
Battery Endurance and Customizable Airflow for All-Day Use
Battery life is critical for any personal cooling wearable meant to be worn beyond short commutes. Sony says the Reon Pocket Pro Plus can run for up to 10 hours on a single charge when set to the second-highest cooling level, making it suitable for most working days or travel schedules without constant recharging. That endurance is complemented by adjustable airflow and multiple cooling modes that let users fine-tune intensity based on activity and environment. Through the companion app, owners can tweak temperature levels, fan behaviour, and automation settings, while onboard controls keep basic operation accessible without a smartphone. Bundled with the unit is the second-generation Reon Pocket Tag, a smaller sensing accessory that measures ambient temperature and humidity. By feeding environmental data into Sony’s thermal comfort technology, the system can deliver more consistent cooling that feels tailored rather than simply blasting maximum power.
