The PERIMICE-522 and PERIMICE-822IR bring symmetrical designs, silent clicks and customisable 3D-printed accessories, with the wireless model adding Bluetooth and 2.4GHz connectivity.
Perixx has expanded its trackball range with two new symmetrical models, the PERIMICE-522 and PERIMICE-822IR, both built around a 40mm ball positioned for index-finger use rather than the thumb-driven layout common on many competing devices. The company is pitching the design as an ergonomic alternative for users who want cursor control without moving the mouse across a desk, a format that can also be practical in tighter workspaces. According to Perixx and product listings from its regional sites, the two devices share the same core shape and control layout, including silent-click buttons and programmable functions.
The main difference is connectivity. The PERIMICE-522 is a wired model, while the PERIMICE-822IR adds three connection modes, including USB, 2.4GHz wireless and Bluetooth, according to Perixx’s product materials. Both devices offer four sensitivity settings at 400, 800, 1,200 and 2,400 CPI, allowing users to tune pointer speed to different tasks. Perixx also says the buttons can be configured without extra software, which may appeal to people who prefer a simpler setup process.
Perixx is also leaning on customisation. The mice include an expansion slot on the underside for compatible 3D-printed add-ons, and Japanese and US listings describe the feature as a way to alter tilt angles or attach other accessories. That makes the launch part of a broader move towards user-adjustable ergonomic peripherals, particularly for people trying to reduce wrist strain during long sessions. The devices are also designed to use a 40mm ball that can be controlled by the index finger, a layout highlighted by Japanese tech outlets as well suited to desk-bound use and restricted spaces.
Pricing places the new models in the budget-to-mid-range segment. The wired PERIMICE-522 starts at $39.99, or ¥5,999 in Japan, while the PERIMICE-822IR is listed at $49.99, or ¥7,999. Perixx has not given a full regional rollout schedule in the material supplied, so availability outside the markets already mentioned remains unclear. Even so, the pricing gap is modest, which may make the wireless version the more attractive option for buyers who want Bluetooth and 2.4GHz support as standard.
