Features of the GameSir X3 Pro

1. Customizable & Modular Design
Unlike other mobile controllers, the GameSir X3 Pro features a highly modular design. The grips are detachable, revealing an additional set of rubberized grips underneath for a comfortable feel. The face buttons are magnetically attached, allowing users to swap them out based on their preferences. Gamers can rearrange button layouts to match their desired control scheme, making the X3 Pro highly flexible.
Additionally, the controller features mechanical switches for the buttons and triggers, providing a satisfying tactile response. While the triggers lack analog control, they remain highly responsive, making them well-suited for most mobile games.
2. Built-in Cooling Fan for Heat Management
One of the standout features of the X3 Pro is its 900mm² cooling plate, which significantly reduces smartphone temperature during extended gaming sessions. The fan has two modes—Quiet Mode and Quick Chilling Mode—allowing users to adjust cooling levels based on their needs.
While the cooling system is effective, it requires an external power source. This means users need to connect the controller to a power bank or wall adapter to activate the fan, which can be inconvenient for on-the-go gaming.
3. Low-Latency Wired Connection
The GameSir X3 Pro connects via USB Type-C, ensuring zero input lag. Unlike Bluetooth controllers, which can introduce latency, the X3 Pro provides instant response times, making it ideal for fast-paced games like Call of Duty: Mobile and Dead Cells.
The controller supports two operating modes—DS5 (PlayStation layout) and Android mode (Xbox-style icons)—allowing users to switch between control schemes for different games.
4. 3.5mm Audio Jack for Wired Headsets
Many mobile controllers block access to the smartphone’s headphone jack, forcing players to rely on Bluetooth headsets. The GameSir X3 Pro includes a dedicated 3.5mm audio port, allowing players to use wired headphones while gaming.

Performance & Usability
The GameSir X3 Pro delivers exceptional performance with its low-latency USB connection, tactile mechanical buttons, and responsive analog sticks. The Hall Effect sticks eliminate drifting issues common in traditional controllers, ensuring long-term durability. The cooling system effectively prevents overheating, keeping smartphone temperatures below 40°C during demanding gaming sessions.
However, the need for external power for the fan and difficulty fitting larger smartphones may be frustrating for some users. Despite these minor drawbacks, the X3 Pro provides a solid, immersive gaming experience at an affordable price.

Additionally, the ability to swap out buttons and grips offers a level of personalization rarely seen in mobile controllers, making it a great fit for gamers who like to fine-tune their setup.
The built-in fan significantly improves thermal management, allowing for longer gaming sessions without overheating concerns. While the need for an external power source may seem inconvenient, it ensures optimal cooling performance, making the X3 Pro a unique offering in the mobile gaming space. Gamers who play graphically demanding titles or use emulators will especially appreciate this feature.
For gamers looking for a wired, low-latency experience with effective cooling, the X3 Pro is a solid investment. Its plug-and-play connectivity ensures instant pairing without latency issues, making it ideal for competitive gameplay. However, those who prioritize portability and wireless connectivity may prefer Bluetooth controllers, as the X3 Pro’s reliance on a USB-C connection can be limiting.
That said, the X3 Pro is not without its drawbacks. The cooling pad requires direct contact with the phone, meaning users must remove thick cases, which may be inconvenient. Additionally, the lack of analog triggers may disappoint racing game enthusiasts who rely on nuanced acceleration and braking. Despite these minor issues, the GameSir X3 Pro remains a standout choice for dedicated mobile gamers looking for a reliable and innovative controller.
