In May 2026, Sony announced the REON Pocket Pro Plus, the successor to the REON Pocket Pro from 2025, and the new flagship in Sony’s line of wearable thermal devices. Both units are built on the same basic thermoelectric (Peltier) technology and twin thermo-module hardware, but the Pro Plus receives targeted enhancements in cooling performance, neckband stability and the accompanying accessory, REON Pocket TAG 2.
For those sweating during congested commutes, working outside in summer heat or suffering in an excessively air-conditioned workplace, these enhancements are more than cosmetic. Here’s a full analysis of what actually changed.

A new optimised cooling algorithm and high-efficiency thermal design deliver 20% more cooling output versus the Pocket Pro, with the contact surface running an additional 2°C colder in Smart Cool mode.
The redesigned ‘Adaptive Hold Design’ neckband increases holding force by 40%, keeping the device in consistent contact with skin during movement — critical for effective heat transfer.
The exhaust vent can now rise above high collars, enabling proper heat dissipation regardless of what you’re wearing. Previous models had fixed short/long vent covers with less flexibility.
The bundled REON Pocket TAG 2 is 18% smaller than the original TAG, replaces the rear clip with a strap hole and carabiner, and supports more versatile attachment to bags, belts, or accessories.
The headline figure is the −2°C improvement in surface temperature — a difference that may sound modest but is meaningful in practice. Critics of the original Reon Pro noted it created a cold spot at the neck without necessarily cooling the whole body. Sony claims the Pro Plus addresses this, with better-dispersed cooling across the upper body thanks to the improved algorithm.
The neckband redesign tackles perhaps the most common complaint about the series: the device shifting during walking. A 40% increase in holding force means the cooling plate stays in proper skin contact rather than drifting, directly preserving cooling efficiency throughout a commute or outdoor session.
The adjustable air vent is a practical quality-of-life fix. Earlier models required users to select between short and long vent covers depending on collar height — a fiddly solution. The Pro Plus lets you adjust the vent position dynamically, making it work better with more outfit types without swapping accessories.
Battery life remains essentially unchanged — up to 15 hours in Smart Cool mode and around 10 hours on higher settings — which was already solid for an all-day use case.
Existing Reon Pocket Pro owner? Sony has confirmed you can partially upgrade to Pro Plus performance simply by purchasing the new Reon Pocket Pro Plus Neckband (S$35) and installing a firmware update — without buying a whole new unit. This is a rare and welcome approach to hardware upgrades.
Buy the Pro Plus if: You’re new to the REON ecosystem, live in a hot/humid climate, commute frequently in summer, or work outdoors. The performance gains and neckband improvements make this the definitive version of the concept.
Keep your Reon Pro if: You bought it recently and primarily use it in mild conditions. Consider the neckband upgrade instead — it captures most of the wearability improvements at a fraction of the cost.
Availability note: At launch, the Pro Plus is on sale in the UK (£199), Europe (€229), and select Asian markets, including Singapore (S$349). A US launch is expected in summer 2026, available directly through the Sony Store.
Largely yes — both devices use the same dual thermo-module core hardware. The major differences are software-level (new cooling algorithm) and accessory-level (new neckband and TAG 2 sensor). Sony explicitly allows existing Reon Pocket Pro owners to upgrade via a new neckband + firmware update.
It uses the Peltier effect — an electrically cooled metal plate sits against the base of the neck, where the body’s circulatory system runs close to the skin surface. Cooling that point helps lower perceived body temperature more efficiently than cooling an arm or chest. A built-in fan circulates air to dissipate heat generated by the process.
Not at launch. As of May 2026, it’s available in the UK (£199), Europe (€229), and select Asian markets. Sony has signalled a US launch is expected in Summer 2026, available only through the Sony Store directly. You can sign up for their mailing list for availability alerts.
The TAG 2 is a compact wearable sensor that measures ambient temperature and humidity. When paired with the main unit, it helps the device automatically adjust cooling intensity based on your environment — this is what drives the Smart Cool mode. It’s included with the Pro Plus kit. It’s 18% smaller than its predecessor and now attaches via a strap hole and carabiner rather than a rear clip.
Up to 15 hours in Smart Cool mode (which automatically adjusts intensity). On higher fixed cooling settings, expect around 10 hours. At maximum intensity (Level 5+), it requires USB power. Battery performance is broadly unchanged from the Reon Pocket Pro.
Yes. The device includes both a Smart Cool mode for summer conditions and a Smart Warm mode for colder environments. It works year-round as a personal temperature regulator, not just a summer gadget.
Yes — it’s specifically designed to be worn under a shirt or top. The new adjustable air vent is a direct improvement for this use case, allowing the exhaust to work properly even with higher shirt collars. The device uses Bluetooth to connect to your phone app for adjustments since the physical buttons are harder to reach while wearing it.
The Pro Plus is the flagship model; the Reon Pocket 6 is the refreshed base model. The Pocket 6 inherits the dual thermo-module from the Pro series and brings the baseline up to speed, but the Pro Plus retains the top-tier position with the Adaptive Hold neckband and advanced cooling algorithm.
