Sony has unveiled the new Reon Pocket Pro Plus, an upgraded version of its neck-worn portable air conditioner. The new device features improved cooling technology and a redesigned design that allows for better ventilation of hot air away from the user. This innovation comes at a time when climate change and rising temperatures are making personal cooling systems increasingly essential to everyday life.

The Reon Pocket Pro Plus works differently than other devices like the Dyson HushJet Mini Cool , which simply blasts air. Instead, Sony 's new device uses a cold metal plate that's pressed against the skin, similar to the Shark ChillPill cooling plate accessory . The device features upgraded flexible arms that wrap around the neck, securing the device to the upper back. This conductive approach is proven to be more effective in high-humidity environments, where exhaust systems fail.
Compared to last year’s model, the surface temperature of the plate has been reduced by an additional two degrees Celsius. The device operates with an “advanced cooling algorithm” that Sony claims provides a 20% improvement in cooling performance. This technological advancement reflects the growing demand for personal air conditioning systems, particularly in Japan where temperatures continue to rise and heat waves become more frequent and intense. This improvement is achieved through dual independent thermo-modules that alternate their intensity for sustained cooling.
Improved features of Reon Pocket Pro Plus
Among the most significant upgrades is a redesigned exhaust vent for the Reon Pocket Pro Plus. Users can now extend its length and adjust its angle, ensuring that hot air is directed away from the body, even when wearing a high-collared shirt. This improvement addresses one of the main problems of previous models, where hot air could get trapped under clothing, reducing cooling efficiency and creating discomfort.
The Pro Plus also works with a new Reon Pocket Tag 2 sensor , which is now 18% smaller and features a design that allows it to be hung from a belt or carabiner for more accurate temperature and humidity measurements. This sensor provides real-time data that helps the device automatically adjust its performance. Bluetooth 5.0 LE technology allows connection with iOS 16+ and Android 9+ apps for SMART COOL/WARM functions with up to 15 hours of autonomy . Compared to the Reon Pocket Pro Plus ,

The REON POCKET series was launched in 2020 in response to Japan’s increasing heat waves and urban heat island effects. The first REON POCKET was a compact device with Peltier technology worn around the neck to cool or warm the upper back through conduction. Subsequent iterative upgrades included the REON POCKET 2 (2021) with improved battery life, the REON POCKET 3 (2022) with app control and global expansion, and the REON POCKET 4 (2023) with enhanced sensors. Each generation addressed specific issues reported by users, such as ergonomics, noise, and cooling efficiency.
Technical specifications and practical usage tips
The Reon Pocket Pro Plus has dimensions of 58x36x134mm for the main unit and a weight of approximately 194-252g with accessories. The device operates in a temperature range of 5-40°C and offers a 50% noise reduction compared to previous models. For optimal performance, it is recommended to place the Tag 2 in a location that is not affected by direct sunlight or air conditioning. Charging takes 130 minutes for 90% and 200 minutes for full charge via USB-C. Users should regularly clean the contact surface and avoid using it in a wet environment for a longer lifespan.
The portable cooling market is part of the $2.5 billion (2025 estimate) personal thermal devices sector , which is projected to reach $5.8 billion by 2030. Japan leads with a 70% market share due to the “heatstroke economy.” Key competitors include the Dyson Zone , Embr Wave 2 , and Chinese alternatives like the Xiaomi Mijia Neck Fan . The trend is shifting away from fan systems (noisy, evaporative) toward conduction cooling with Peltier for silent, moisture-resistant performance.
According to Yusuke Itoh, product manager of Sony REON POCKET, “public sensitivity to heat is increasing year by year, creating stronger demand for premium countermeasures.” The PRO model recorded 15,000 orders in Japan within two days of its release, causing shortages. Gartner note that the dual-module innovation doubles cooling efficiency in high-humidity environments, outperforming competitors by 40% in user comfort ratings.

The future of portable cooling technology looks promising, with predictions for AI personalization and integration with biometric data by 2027. Sony is targeting global expansion in 30+ markets, with the market expected to reach $10 billion by 2032. Despite a premium price of around 30,000 yen ($200), the rapid adoption shows that consumers are willing to invest in personal comfort as climate conditions become more extreme.
