The GameSir T4 Pro follows an asymmetrical joystick layout, placing the thumbsticks in offset positions in line with that familiar controller arrangement. It weighs 204 g and measures 151 mm wide, 106 mm tall, and 60 mm thick, giving it a mid-size build that balances portability with a substantial feel in hand. The triggers and bumpers have a smooth finish, as the controller does not feature any textured surfaces on those inputs.
The GameSir T4 Pro offers a total of 18 buttons, including paddle buttons that provide additional input options without repositioning the thumbs. Both thumbsticks are analog in type, and the controller supports full button mapping, allowing inputs to be reassigned to suit different play styles. Hall effect triggers, adaptive triggers, interchangeable thumbsticks, and an integrated touchpad are not part of this controller's feature set.
The GameSir T4 Pro is powered by an internal rechargeable battery rated for up to 40 hours of use, with a full charge taking approximately 2 hours. It connects via 2.4GHz wireless or USB, giving users flexibility depending on their setup. The controller is compatible with PC and Nintendo Switch.
The GameSir T4 Pro operates at a 200 Hz polling rate and includes both gyroscopic aiming and dual force feedback, adding motion-based input and haptic response to its feature set. On the audio side, there is no built-in speaker, built-in microphone, or 3.5 mm headset jack. The controller does not come bundled with a charging dock or a travel bag, and it carries a one-year warranty.
