Wearable climate control often feels like a novelty, but Sony has been steadily developing its Reon Pocket lineup in Japan since 2019. Now, the company is launching its latest version, the Reon Pocket Pro Plus, in the US. Retailing for €229 in Europe and £199 in the UK (approximately $268), this compact device is a personal temperature regulator designed to rest on the back of your neck.

Sony Reon Pocket Pro Plus Specifications
According to Sony, this version improves cooling performance by 20% compared to the previous generation. The cooling plate can drop an additional 2 degrees Celsius, which should make a noticeable difference in how cold it actually feels against your skin when you are walking outside.
The physical design has also been tweaked to make it easier to wear. Sony added a flexible neckband that grips your shoulders a bit better, keeping the main unit from shifting around when you walk or bend over. More importantly, the exhaust vent is now adjustable. You can extend it and change the angle so that the hot air blowing out of the device doesn’t get trapped under a high shirt collar or jacket.
Inside, the device uses dual thermo-modules and a sensor system to monitor your skin temperature. If you use the companion app, you can set a target temperature, and the device’s smart modes will automatically adjust its output as your environment changes. If you don’t want to rely on your phone, there are physical buttons on the side to turn it on and switch between heating and cooling modes.


Sony says the battery lasts up to 15 hours on the smart cooling setting, and because it operates quietly, you can wear it indoors or at work without bothering anyone. The company is also offering a companion accessory called the Wearable Sensing Device (or Reon Pocket Tag 2). It is a small sensor you can clip to your bag or belt loop that measures the ambient temperature and humidity, feeding that data back to the main unit so it can adjust itself more accurately.
The Reon Pocket Pro Plus will be sold exclusively through Sony’s online store in the US starting in the summer of 2026. The exact US pricing isn’t announced yet.
In related news, Sony has recently introduced the Sony Bravia 3 II with AI-powered picture enhancements, 4K 120Hz gaming support, and display sizes going up to 100 inches.
