Sony's neck-worn wearable air conditioner chills only a patch of skin, not the room
Sony's Reon Pocket Pro Plus uses a Peltier cooling module placed at the base of the neck to create a cool sensation; it cools only a small patch of skin, not the surrounding air, and whole-body comfort is more influenced by facial cooling in studies. Sony claims about 2°C better performance over prior models in lab tests; availability remains Japan-first with uncertain U.S. release.
