Keychron T1 HE trackball mouse lets you adjust the ball position

What the T1 HE offers

Keychron has opened preorders for a new wireless trackball mouse called the T1 HE, according to The Verge. The device costs $59.99 and comes in black, white or translucent finishes. Shipping is expected to begin in early December.

The standout feature is adjustability. Two dials on the underside of the mouse move the 34mm trackball vertically and horizontally, and the ball can also be extended or retracted. The range is only a few millimetres in each direction, but Keychron says this lets each user place the ball squarely under the thumb without reaching.

A different shape from the Nape Pro

The T1 HE follows the Nape Pro, Keychron's first trackball device, which was shown at CES 2026. The Nape Pro had a slim, compact body designed to sit right up against a keyboard.

The new model looks more like traditional trackball mice from companies such as Logitech and Kensington. Its ball sits on the side of the body, a layout intended to improve ergonomics for the hand and wrist.

Sensors, buttons and battery life

The optical sensor's sensitivity can be set from 100 DPI to 2,400 DPI. A button on the mouse cycles through presets, and the Keychron Launcher software offers further customisation, including button remapping and macros.

The T1 HE has six customisable buttons in total. Keychron says the 600mAh battery lasts up to 106 hours over Bluetooth or 98 hours with the included 2.4GHz wireless receiver. The mouse can also be used while connected by a USB-C cable, so charging does not interrupt work.

Why the adjustable ball matters

Trackball mice rest in one place on the desk, so the position of the ball decides where the thumb sits during use. Hands and fingers vary in size, and a fixed ball position can force some users to stretch or grip awkwardly.

By allowing small positional changes, Keychron is aiming to make the T1 HE comfortable for more people. The company has not announced a firm shipping date beyond early December, and independent reviews of the device are not yet available.
