Sony REON POCKET PRO Showcased at CEATEC 2025: A Leap in Good Wearable Temperature Management With New Twin-Module Thermal System

At CEATEC 2025, Sony showcased its newest private thermo gadget, the REON POCKET PRO *, a high-end evolution of the REON lineup that started in Japan in 2020. Regardless that we couldn’t contact the unit, the Sony representatives supplied detailed explanations of what makes this new mannequin considerably extra succesful than earlier generations. Based mostly on what I noticed and what the Sony representatives defined, the REON POCKET PRO represents Sony’s most polished try at private local weather management, offering cooling throughout summer season and warming throughout winter in a compact, neck-worn kind issue.

This dual-season functionality is central to the product: the gadget actively cools the pores and skin when the climate is scorching and warms the pores and skin when temperatures drop. Sony’s spokesperson even pointed to the “chilly aspect” and “heat aspect” throughout our dialog, confirming that the module reverses its perform relying on seasonal wants.

Since its inception, REON POCKET has not been merely a aspect challenge — it started in 2019 inside the Sony Acceleration Platform, the corporate’s inner incubator for brand new enterprise concepts. The idea originated with Kenji Itoh, a former Sony digicam engineer who later grew to become the CEO of Sony Thermo Know-how Inc. when it spun off as an impartial firm in October 2023. Itoh’s private expertise with the distinction between outside warmth and intense indoor air-conditioning impressed the concept of “moveable temperature consolation.” With the REON POCKET PRO, Sony now goals to convey the technology to 22 international locations worldwide and increase it past client wearables into enterprise and industrial functions.

A Main {Hardware} Leap: Twin Thermo-Modules + Greater All the pieces

In line with Sony, the most important improve within the PRO mannequin is the transfer to two impartial thermo-modules, changing the single-module system of the sooner fashions. These modules alternate intensities to keep up steady cooling or warming, enabling the PRO to maintain a considerably extra steady output. The corporate claims this strategy doubles the efficient cooling and warming space, considerably improves warmth absorption, and allows the gadget to keep up greater efficiency over longer durations.

In comparison with the earlier mannequin, the REON POCKET 5 * , the PRO presents roughly:

• 2× the cooling/warming floor space
• 2× the warmth absorption capability
• 2× the utmost working time

To help this, Sony designed a new high-efficiency heat-sink fan that delivers twice the airflow in comparison with the REON POCKET 5. In line with the corporate, the PRO operates at 50% decrease noise, making it appropriate for enterprise and commuting environments.

Battery life has additionally been upgraded considerably. The PRO now presents as much as 34 hours of operation at Cooling Degree 1 — one other enchancment that basically doubles the endurance of the REON POCKET 5. Increased cooling ranges nonetheless scale back battery life, however the baseline runtime is now far more sensible for lengthy days.

A Extra Refined and Useful Design

The REON POCKET PRO instantly appeared extra polished {and professional} than the REON POCKET 5. Sony refined the general construction with a curved heat-transfer plate that follows the pure contour of the higher backbone, enhancing anatomical contact to assist distribute the thermal impact extra evenly.

The neckband has been re-engineered to be wider and extra versatile, and is bolstered with silicone extensions that improve stability throughout motion. The outside contains a extra business-oriented matte end designed to stay discreet below clothes, making it appropriate for each day commuting or workplace environments.

These modifications usually are not merely beauty. In line with the Sony consultant, the redesign was pushed by the PRO’s new inner structure — the twin thermo-module system, the higher-capacity warmth sink, and the elevated airflow fan — all of which required a brand new chassis geometry. 

The result’s a tool that appears sleeker on the skin however is considerably extra succesful on the within. Importantly, Sony clarified that the PRO is not a medical gadget and shouldn’t be used as an alternative to heatstroke prevention.

Smarter Seasonal Performance

The REON POCKET PRO retains the identical reversible operation as earlier fashions, providing cooling in summer season and warming in winter, however delivers it with better stability. Whereas earlier generations might generally throttle below prolonged hundreds, the PRO’s dual-module design and improved airflow assist the gadget keep efficiency extra constantly.

Sony additionally upgraded the SMART COOL mode. By utilizing sensors for temperature, humidity, and motion, the PRO mechanically adjusts its depth extra effectively. In line with SONY, the new algorithm performs higher than the one used within the REON POCKET 5, optimizing battery life and thermal output extra intelligently.

Bodily buttons are nonetheless current for direct management, making it simple to regulate modes with out pulling out your telephone.

The place It Suits within the REON Lineup

The REON POCKET PRO sits on the high of Sony’s lineup and is positioned because the high-performance mannequin above the REON POCKET 5. The 2 units coexist: the REON POCKET 5 remains to be out there for customers who desire a lighter, easier, and extra inexpensive possibility, whereas the PRO is supposed for customers who prioritize energy, endurance, and luxury.

Sony launched the PRO earlier this 12 months in Japan and has expanded distribution to Europe, the Center East, and choose Asia-Pacific markets. It’s not formally bought in the US.

Sensible Use Instances — and Limitations

Like earlier REON fashions, the PRO targets conditions the place full-room air-con is unavailable or impractical: crowded public transport, overheated workplaces, or outside commutes. Its localized thermal impact stays centered on the neck space and doesn’t exchange full-body cooling or heating.

The gadget is splash-resistant however not waterproof. And whereas Sony improved battery life and efficiency, the very best cooling ranges nonetheless drain the battery quicker.

Nevertheless, for customers who already depend on or admire the REON POCKET 5, the PRO seems to ship precisely what was requested: stronger efficiency, longer runtime, quieter operation, and a extra refined design.

Conclusion: A Vital Step Ahead for Sony’s REON Line

With the REON POCKET PRO, Sony designed a way more succesful successor to the REON POCKET 5. The transfer to a dual-module system, the improved dissipation, the longer battery life, and the redesigned chassis work collectively to ship a tool that feels prepared for real-world all-day use. If these specs translate into actual efficiency, the REON POCKET PRO might turn into Sony’s most convincing wearable local weather gadget but.
