It tries to hide itself and fails, which feels worse than simply being visible.
In the long human search for comfort against the elements, Sony's Reon Pocket Pro Plus arrives as a $260 wearable that cools the nape of the neck through thermoelectric engineering — a genuinely clever answer to heat that, when carried into the world, finds the world not quite ready for it. Tested on the streets of Chicago, the device retreated indoors almost as quickly as it ventured out, not because the technology failed, but because the gap between what a product can do and what a person can comfortably be seen doing remains one of design's oldest and most humbling distances.
- Sony's thermoelectric neck cooler delivers real, ice-cold relief and up to 15 hours of smart battery life — the engineering is not in question.
- The device is too bulky to hide, visibly distorting collars and creating a retro-futuristic bulge that draws exactly the attention it was designed to avoid.
- It cannot be worn in rain, snow, or direct sunlight, and sweating — the very condition that demands cooling — renders it unwearable, gutting its outdoor utility.
- At $260, it faces cheaper rivals like the $99 Dyson HushJet and $149 Shark ChillPill, while its own niche use case narrows with every real-world limitation discovered.
- The device is landing as a curiosity for a narrow audience — outdoor workers willing to pay the price in both dollars and social discomfort — while most consumers are left looking elsewhere.
After years of testing wearables across Chicago — smart glasses, fitness trackers, body-mounted fans — the Reon Pocket Pro Plus prompted a retreat half a block from home. The self-consciousness was immediate and decisive. That moment, it turned out, was the review in miniature.
The device itself is genuinely impressive in isolation. A thermoelectric metal plate rests against the nape of the neck, cooling or heating on command via buttons or an app. On maximum cooling, the plate turns ice-cold. A separate sensing tag reads ambient temperature and adjusts automatically based on body heat and movement. Battery life holds to around eight hours of mixed use, consistent with Sony's 15-hour smart-mode claim. For something this compact, the engineering is hard to fault.
But the real world is unforgiving. The Reon is roughly five inches wide and weighs over nine ounces — substantial for an under-clothing device. It is neither waterproof nor weatherproof, which is a strange limitation for a product aimed at outdoor workers. Sweating defeats it. Rain defeats it. Prolonged sunlight is warned against in the manual. The cooling plate covers only a small area of skin, and even that modest benefit is undermined by a design that constantly shifts out of position during light activity, creates pressure points, and — when the wearer bends forward — redirects hot exhaust air directly onto the neck.
Visibility is the sharpest problem. Sony's marketing implies the device disappears beneath clothing. It does not. The bulge at the collar is noticeable, and the curved black plastic arms carry a distinctly 1980s sci-fi quality. A product that tries to hide and fails reads as stranger than one that simply announces itself.
The Reon Pocket Pro Plus is Sony's first U.S. release after years of overseas versions, and it includes real refinements — an extendable exhaust vent, an improved neck band, smarter sensors. Competitors like the Dyson HushJet Mini Cool at $99 and the Shark ChillPill at $149 have since entered the space at lower prices. For a construction worker or landscaper enduring extreme heat with limited alternatives, the $260 price and the social cost might be worth it. For most people, the trade-offs simply don't add up — and on the hottest days, when cooling matters most, the device can't be worn at all.
I've tested wearables across Chicago for years—smart glasses, dual fitness trackers, portable fans strapped to my body. But when I stepped out with Sony's Reon Pocket Pro Plus, a $260 personal cooling device designed to nestle against the back of my neck, I made it half a block before the self-consciousness became unbearable. I turned around and went home, resolving to finish my evaluation indoors.
That premature retreat proved prophetic. The Reon Pocket Pro Plus is genuinely clever engineering housed in a device that, in practice, doesn't belong in public. A thermoelectric metal plate rests directly against your skin at the nape of your neck, heating or cooling on command through physical buttons or a companion app. The technology works—impressively so. On maximum cooling, the plate turns ice-cold. The battery stretches to around eight hours under mixed use, aligning with Sony's claim of up to fifteen hours in smart mode. The device includes a separate sensing tag that detects ambient temperature, allowing the Reon to adjust automatically based on your body temperature, movement, and environment. For a wearable this compact, packing both heating and cooling capabilities alongside multiple sensors represents solid engineering.
But engineering alone doesn't make a product livable. The Reon measures roughly five inches wide and weighs over nine ounces—substantial for something you're meant to wear under your clothes. It's not waterproof or weatherproof, which severely limits its utility for the outdoor workers it's theoretically designed for. You can't wear it if you're sweating. You can't wear it in rain or snow. The manual warns against prolonged direct sunlight. The metal plate only cools a small area at the back of your neck, an intentional design choice Sony justified by noting that region's sensitivity to temperature. In theory, this makes sense. In practice, the effect is modest and constantly undermined by the device's other problems.
The most glaring issue is visibility. Sony's marketing suggests the Reon disappears under clothing. It doesn't. Even wearing it beneath a shirt, the device visibly altered the shape of my collar and created a pronounced bulge at the back of my neck—noticeable enough that I'd be surprised if anyone looking at me for more than a moment didn't notice something was wrong. The black plastic arms that curve forward to hold the device in place have a distinctly retro-futuristic appearance, like something from an 1980s sci-fi film. The device tries to hide itself and fails, which feels worse than simply being visible.
Beyond aesthetics, the Reon is uncomfortable to wear. The metal plate constantly shifted away from my skin during light activity, requiring frequent adjustment. The arms, while sturdy enough to keep the device from falling, created persistent pressure points. Worse, when I bent over, my shirt would cover the exhaust vent for a moment, redirecting hot air directly onto my neck—an unpleasant surprise on an already awkward device. The small contact area of the cooling plate meant that even when properly positioned, the comfort benefit was marginal.
Sony released earlier versions of the Reon overseas starting in 2019, making it a relative veteran in the wearable cooling space, though newer competitors like the Dyson HushJet Mini Cool ($99.99) and Shark ChillPill ($149.99) have since arrived. The Pocket Pro Plus is the first U.S. release and includes refinements: an extendable exhaust vent for better angle control, an improved neck band, and upgraded sensors for smarter temperature adjustment. These improvements matter, but they don't solve the fundamental problem: a device that works in isolation but fails in the real world.
For someone working outdoors in extreme heat—a construction worker, a landscaper, someone with limited access to air conditioning—the Reon might justify its $260 price tag and the social cost of wearing it. The cooling is genuine, the battery life is respectable, and the engineering is undeniably impressive. But for most people, the trade-offs don't pencil out. On truly hot days, you won't wear it because sweating defeats the purpose. On cold days, a five-dollar hand warmer tucked into your collar accomplishes roughly the same thing without the bulk or the stares. The Reon Pocket Pro Plus is a solution in search of a problem most of us don't actually have.

You made it half a block. What changed your mind?
The visibility. I thought it would be a subtle bulge under my shirt, something only noticeable if someone was really looking. Instead, it warped the shape of my entire collar and created this obvious protrusion at the back of my neck. I felt like I was wearing something I was trying to hide and doing a terrible job of it.
But the cooling itself works?
Genuinely impressive. On maximum, the metal plate gets ice-cold. The battery lasted eight hours under mixed use, which tracks with Sony's estimates. The engineering is clever—heating, cooling, multiple sensors, all in something that fits in your hand.
So why not just wear it indoors, where you don't care what people think?
Because even indoors, it's uncomfortable. The plate keeps shifting. When you bend over, your shirt covers the exhaust vent and blasts hot air back at you. And the actual cooling effect is limited to a small area at the back of your neck. The discomfort undermines whatever benefit you're getting.
Who is this for, then?
Maybe outdoor workers in extreme heat who can't access air conditioning and are willing to accept the social cost. Construction workers, landscapers, people in that category. But even then, you can't wear it if you're sweating, which defeats the purpose for anyone doing physical labor.
At $260, that's a narrow market.
Extremely narrow. A five-dollar hand warmer does roughly the same thing on cold days. On hot days, you're better off with a cheaper portable fan. The Reon is solving a problem that most people either don't have or have already solved.
