GameSir X2 Pro Xbox Mobile Game Controller Review


  • Responsive controls

  • Includes carrying case

The GameSir X2 Pro is a standout mobile game controller that sails past its competitors.

About the GameSir X2 Pro Xbox Mobile Game Controller

  • Price: $80
  • Connectivity: USB-C (connect to device), USB-C (pass-through charging)
  • Dimensions: 7.24 x 3.34 x 1.45 inches
  • Weight: 0.4 lbs
  • Special features: Hall effect trigger, Kailh microswitch bumpers, passthrough charging station, two mappable back buttons, textured rubber. Includes one month of Xbox Game Pass Ultimate for free.

The GameSir X2 Pro is compatible with Android 8.0+ smartphones that are 7.04 inches (179mm) long or shorter.

The buttons on the X2 Pro are just as clicky and responsive as larger mobile gaming controllers like the Razer Kishi V2 and Backbone One. The M1 and M2 buttons are on the bottom back of the X2 Pro, while the Kishi V2’s M buttons are small squares located next to the shutter button on top of the controller. (The Backbone One omits M buttons.)

While button location is a personal preference, gamers with small hands and/or short fingers will probably prefer Razer’s Kishi V2 M-button layout as they are much easier to reach; I had to stretch and contort my fingers to touch the X2 Pro’s M buttons on the back with my fingertips, which became uncomfortable after a while. However, I had no problems with my hands getting hot or sweaty even after playing for over 60 minutes.

The X2 Pro’s thumbsticks don’t have the same tactile feel as the Kishi and Backbone (which have a slight bump when you move the thumbsticks in any direction), but the movement of the GameSir is completely smooth. In practice, this has little to no effect on in-game precision.

There’s also a USB-C passthrough built into the controller for charging your phone while you play and a dedicated Xbox button. Of course, since this is an official Xbox-licensed controller, it’s designed to work seamlessly with Xbox Cloud Gaming, but it also works with other popular cloud gaming platforms like GeForce Now, as well as locally installed games.

For $80, GameSir gives you a quality mobile controller with a carrying case and four extra thumbsticks.

In terms of design, the X2 Pro has subtle quality differences that I prefer over the Kishi V2 and Backbone One. The first is a wide adjustable back that supports the entire width of your phone up to almost 3.5 inches; the second is a rubber (albeit hard) cushion that protects the very top and bottom edges of your phone.

The Kishi V2 and the Backbone One have the same features, but neither is as broad. Their adjustable backs are under 1.5 inches wide and both have shorter rubber cushions that don’t wrap around to protect the top and bottom edges of your phone.

As a final bonus, GameSir bundles its X2 Pro controller with a well-constructed carrying case, something the Razer Kishi and Backbone lack. You can find one from a third party for around $15 to $20, but that pushes the price of both controllers to $120, while the X2 Pro stays well below that amount.

Should you buy the GameSir X2 Pro Xbox Mobile Controller?

Yes, it’s a great controller that comes with complementary extras

Functionally, GameSir X2 Pro isn’t all that different from other popular controllers that plug into your mobile device like the Razer Kishi V2 and Backbone One. It’s responsive, well-engineered and works seamlessly with Xbox Cloud Gaming and other platforms.

For $80, about $20 less than the competition, the GameSir X2 Pro comes with a few extras like interchangeable action buttons, M-buttons, and a free carrying case that won’t take up much space in your shoulder bag or backpack. All these extras, in addition to being a great mobile controller in its own right, make the GameSir’s X2 Pro a compelling buy.
