Mistel launches AIRONE PRO with Ultra-Thin Cherry MX ULP Switches

Taiwan-based keyboard maker Mistel has introduced the AIRONE PRO, a 65% mechanical keyboard built around Cherry MX ULP (Ultra Low Profile) switches. The company announced the board in early February 2025.

At its core are Cherry’s ultra-low-profile switches, measuring roughly 3.5 mm in total height with 1.8 mm of key travel — significantly thinner and shorter than standard MX switches. Buyers can choose between tactile and linear variants.

Cherry MX ULP switches are typically used in ultra-slim laptops and premium low-profile keyboards where minimizing thickness is a priority. They’re far less common in enthusiast desktop boards, largely because the shorter travel changes typing feel and limits keycap compatibility compared to traditional MX designs.

Compact 65% layout with a catch for US Buyers

The AIRONE PRO uses a 65% layout, removing the numpad and function row while retaining arrow keys and navigation controls — a popular format for compact desk setups.

However, there’s an important caveat: the keyboard ships with a JIS (Japanese) layout, not the standard ANSI layout used in the United States. That means a different Enter key shape, a shorter spacebar, and additional modifier keys. For US users, this could affect typing muscle memory and limit aftermarket keycap options.

Aluminum build, RGB, and QMK support

The chassis is made from CNC-machined aluminum, and Mistel includes internal sound-dampening materials to reduce resonance — notable in ultra-thin designs, where acoustics can often feel hollow.

Other specs include:

• ABS keycaps with laser-engraved legends
• Full RGB backlighting
• Wired USB connectivity
• 1,000 Hz polling rate (1 ms response time)
• 387 g total weight

On the firmware side, the AIRONE PRO supports QMK and VIA, allowing users to remap keys and create macros without flashing custom firmware — a meaningful advantage for enthusiasts who prioritize customization.

Positioning and availability

The AIRONE PRO appears aimed at users who want a slim mechanical keyboard with enthusiast-grade firmware support — a niche that sits between gaming boards and fully custom builds.

Mistel has not yet announced US pricing or availability details. The JIS-only layout may significantly narrow its appeal outside Japan unless an ANSI variant is released.
