Sony upgrades its neck wearable cooling device with stronger cooling and longer battery life
The device differs from conventional wearable fans by using the Peltier effect, in which an electrically cooled metal plate positioned at the base of the neck helps lower temperatures near the circulatory system
Sony has introduced the Reon Pocket Pro Plus, the latest version of its wearable cooling device line that began development in 2017, featuring enhanced performance, longer battery life and improved fit.
The device differs from conventional wearable fans by using the Peltier effect, in which an electrically cooled metal plate positioned at the base of the neck helps lower temperatures near the circulatory system, says End.
According to Sony, the Pro Plus delivers a 20 percent increase in performance, resulting in a 2.0°C (3.6°F) improvement in cooling compared with its predecessor.

The device incorporates updated algorithms designed to more precisely track temperature changes both on the device and in the surrounding environment.
Despite the increased output, Sony said the device can operate for up to 10 hours when used on its second-highest cooling setting.
The hardware design remains similar to earlier models and is intended to be worn discreetly under clothing. However, it now includes redesigned flexible fins intended to better accommodate different neck shapes. Sony said the changes make the device 40 percent more stable on the user's neck and shoulders.
For safety, the device includes a quiet fan system and an automatic shutdown function designed to prevent overheating.
The Reon Pocket Pro Plus is bundled with a second-generation Pocket Tag, a small accessory that monitors ambient temperature and humidity to help adjust cooling performance. A companion smartphone application is available for manual controls and customisation, although the device can also operate without a smartphone.
Sony has priced the device at £199 in the UK and €220 in Europe. It is currently available through Sony's own stores and retailers including Amazon in those regions. The company has not confirmed a US launch, but said it aims to make the device available before the 2026 summer heatwaves.
