Keychron T1 HE Trackball Mouse

Order via Japan Rabbit

Meet the Keychron T1 HE, a trackball mouse designed to make ergonomic navigation effortless for everyone. Trackballs tend to divide people: once you're used to one, you never want to go back, but for first-timers, they can feel intimidating. The T1 HE was built to change that reputation.

Its smooth, egg-shaped body fits naturally in your hand, breaking away from rigid traditional mouse designs. The standout feature is an adjustable trackball mechanism that lets you fine-tune the ball's position forward, backward, left, right, and in height, so it matches your grip exactly. You can also reassign the buttons and scroll wheel to functions that suit your workflow, then save that custom layout directly to the mouse's onboard memory.

Keychron designed the T1 HE to be more than "just another trackball." The goal was a device you can pick up naturally from day one, and keep shaping to your own habits for years afterward. It follows the same spirit that drove Keychron's collaboration with GIZMODO on the Keychron Nape Pro, a project that raised over 400 million yen. The T1 HE is Keychron's other answer to the trackball, one the brand had been developing even before that.

Whether you're a longtime trackball user chasing the perfect grip or a curious beginner ready to make the switch, the T1 HE gives you a shape you can adjust to fit your hand, not the other way around.
