There is something inherently optimistic, if slightly eccentric, about a company like Sony deciding that the solution to a sweltering summer commute is a miniature air conditioner that you wear like a piece of jewelry at the base of your neck. For years, the Reon series has occupied a strange, liminal space in the tech world—too expensive to be a novelty gadget, yet too niche to be a household staple. It is the kind of product that feels like the passion project of a single, determined executive who refuses to accept that humans must simply suffer through humidity.
The latest iteration, the Reon Pocket Pro, arrives as the new flagship of the lineup, launching with a price tag of £199 or €229. While the device may look like a minor revision of its predecessor, it represents Sony’s continued commitment to “personal climate control,” a category that is increasingly relevant as urban heat islands become more oppressive and global temperatures continue to climb.
As a former software engineer, I tend to look at these devices through the lens of efficiency, and thermodynamics. Most “wearable fans” on the market are essentially just small plastic propellers that move hot air across your skin—which, in high humidity, does very little to actually lower your core temperature. The Reon is fundamentally different. It utilizes the Peltier effect, a thermoelectric cooling system where an electric current creates a temperature difference between two different conductors. One side gets hot, the other gets cold; the cold side is pressed against your skin, while the heat is vented away.
Refining the Ergonomics of Cooling
The updates to the Reon Pocket Pro are subtle, but they target the primary friction points of the previous models: stability and airflow. The most notable physical change is the main outlet vent at the top of the unit. In previous versions, the vent was fixed, meaning the heat exhausted by the Peltier element was pushed in a single direction. The new Pro model features an adjustable vent angle, allowing users to redirect the exhaust air away from their clothing or hair, improving overall comfort.
Stability has also been a recurring critique of the Reon series. Because the device relies on direct skin contact to be effective, any gap between the cooling plate and the neck causes a significant drop in perceived performance. Sony has addressed this with a sturdier, redesigned neckband. This updated strap is intended to hold the unit more securely against the nape of the neck, reducing the “wobble” that often occurs during walking or light activity.
According to Sony, these combined improvements in fit and thermal management result in approximately 20% better cooling performance compared to the last model. While a 20% increase may not seem like a generational leap in computing terms, in the world of thermodynamics, any increase in heat transfer efficiency is a win.
A Smaller Footprint for Control
Beyond the main unit, Sony has shrunk the accompanying remote by roughly 18%. While the device can be controlled via a smartphone app, the dedicated remote is essential for those who don’t want to unlock their phones every time they need to adjust the temperature. The smaller form factor makes it significantly easier to attach to a keyring or lanyard, reducing the mental overhead of carrying yet another piece of proprietary hardware.
The device remains versatile, offering both cooling and warming modes. This makes it a year-round accessory, though its primary utility remains the “cooling” side of the equation. The ability to regulate temperature on the fly is particularly appealing for those who work in environments with inconsistent HVAC systems or for those who suffer from heat sensitivity.
| Feature | Previous Model | Reon Pocket Pro |
|---|---|---|
| Vent Design | Fixed Position | Adjustable Angle |
| Cooling Efficiency | Baseline | ~20% Increase |
| Remote Size | Standard | ~18% Smaller |
| Neckband | Standard Fit | Enhanced Stability |
The High Cost of Niche Comfort
The primary hurdle for the Reon Pocket Pro remains its price. At £199, it is positioned far above the budget neck fans found on Amazon or in electronics stores. For the average consumer, spending two hundred pounds on a wearable cooler is a hard sell. However, the value proposition changes when you consider the target demographic: professionals in formal attire who cannot wear breathable linens in the summer, or people living in hyper-dense cities like Tokyo or London where the “heat island” effect makes outdoor transit grueling.
There is also a broader environmental context to consider. As the climate crisis leads to more frequent and severe heatwaves, the demand for portable, personal cooling solutions is likely to grow. We are seeing a shift where “climate adaptation” is moving from the architectural level (better insulation, green roofs) to the personal level (wearable tech). Sony is betting that as the world gets hotter, the “oddball” nature of the Reon will eventually be viewed as a practical necessity.
Whether the Reon Pocket Pro will ever move from a niche enthusiast product to a mainstream accessory remains to be seen. But from a product development standpoint, it is refreshing to see a tech giant continue to iterate on a weird, specific problem rather than sticking to the safe bets of smartphones and headphones.
Sony has not yet announced a wider release schedule for additional regions beyond its primary markets, but the device is available now through select retailers. Users looking for official support or firmware updates can find documentation on the official Sony global website.
