Keychron has opened preorders for the T1 HE, a wireless trackball mouse whose trackball position can be adjusted to fit different hand sizes. The peripheral maker is selling the mouse through its online store for $59.99 in black, white, or translucent options, with shipping expected to begin in early December.
The T1 HE positions a 34mm ball on its side, a layout similar to trackball mice already sold by Logitech and Kensington, and one the company says improves ergonomics. Two dials on the underside of the mouse move the trackball vertically and horizontally, and the ball can also be extended or retracted. The range of adjustment is limited to a few millimeters in either direction, but Keychron is pitching those small shifts as a way to keep the ball squarely under the thumb without reaching.
The T1 HE follows Keychron’s Nape Pro, the company’s first trackball device, which was introduced at CES 2026 with a slim, compact design meant to sit right up against a keyboard. The T1 HE takes a different approach, adopting the side-mounted ball format familiar from other trackball mice rather than the Nape Pro’s low-profile shape.
Users can change the sensitivity of the T1 HE’s optical sensor from 100 DPI to 2,400 DPI. A button on the mouse cycles through preset sensitivity levels, and Keychron’s Launcher software offers the same adjustment along with other customization, including button remapping and macro creation.
The mouse carries six customizable buttons. Its 600mAh battery is rated for up to 106 hours of use in Bluetooth mode, or 98 hours when connected through the included 2.4GHz wireless receiver. Buyers who would rather not manage charging can also run the T1 HE, which Keychron lists as the T1 HE Wireless Adjustable Trackball Mouse, over a USB-C cable.
The preorder launch puts the T1 HE in the hands of buyers in the US through Keychron’s own store ahead of its expected December ship date. The adjustable trackball mount is the mouse’s main departure from competing trackball designs, which fix the ball in a single position. Keychron has not announced retail partners or other availability beyond its online store.
