Apparently, being too hot or too cold is now something technology can personally take on.
Sony’s REON POCKET PRO Plus Sensing Kit is a wearable cooling and heating device that rests at the back of your neck, delivering cooling or warmth directly to your skin while everyone else argues over the thermostat.
And this isn’t just a tiny fan hanging around your neck. The REON POCKET PRO Plus uses a temperature-controlled surface that sits directly against the back of your neck, delivering cooling or warmth right where you can feel it. Think of it as your own wearable cooling and heating device, designed to go wherever you do.

So, How Does This Thing Actually Work?
The secret is direct contact. Instead of trying to cool or heat the air around you, the REON POCKET PRO Plus uses thermo modules that rest against the back of your neck to deliver cooling or warmth directly to your skin. In COOL mode, two thermo modules alternate in intensity to provide continuous cooling. In WARM mode, you can choose from four levels of warmth.
But here’s where it gets especially clever. The system uses multiple sensors to take things like temperature, humidity and your activity into account. With the included Wearable Sensing Device (TAG) for REON POCKET, it can also sense the environment around you. In its smart modes, it can automatically adjust the cooling or warming as conditions change. It can even switch between COOL and WARM automatically.
In other words, you don’t necessarily have to keep fiddling with it. It’s designed to notice when your surroundings change and adjust along with them.
Feeling Hot? Feeling Cold? Pick a Side.

On hot days, COOL mode provides direct cooling at the back of your neck. When temperatures drop, switch to WARM mode for targeted heat instead. And because the same device handles both, this isn’t something that gets tossed in a drawer once summer is over.
One gadget. Two seasons arguing over who gets to use it.
Okay, But How Do You Wear It?
The REON POCKET PRO Plus is designed to sit at the back of your neck, held in place by an adjustable neckband. The cooling and warming surfaces make direct contact with your skin, while the main body of the device stays behind you rather than hanging in front like a traditional neck fan.
You can control it using the buttons on the device itself or through Sony’s REON POCKET app. And because the neckband is adjustable, you can position the device so the thermo modules sit exactly where they’re supposed to.

Wait, What’s That Little Extra Gadget?
That little oval device isn’t a remote. It’s the TAG, a small wearable sensor included with the REON POCKET PRO Plus Sensing Kit that helps the system understand what’s happening in the environment around you.
The TAG measures environmental conditions, including temperature and humidity, and sends that information to the REON POCKET PRO Plus. That gives the system more information to work with when automatically adjusting its cooling or warming.
So while the REON POCKET PRO Plus is working to keep you comfortable, the TAG is keeping an eye on the environment around you. Hot sidewalk to freezing office? The system is designed to adapt as your surroundings change.


Who Would Benefit From Using This?
Think commuters, travelers, people who spend time outdoors, and anyone who works in an office where the thermostat never seems to agree with them. It could also come in handy for sightseeing, outdoor events, walking around town, or simply moving between places with dramatically different temperatures.
And because the REON POCKET PRO Plus can both cool and warm, it isn’t a one-season gadget. Hot summer days, chilly mornings, overly air-conditioned buildings, and colder weather can all give it something to do.
Basically, if you’ve ever wished you could adjust your own temperature without starting a war over the thermostat, this might be your kind of gadget.
