Microsoft-authorized GameSir X4 launches as Backbone One mobile game controller challenger

GameSir has launched its X4 mobile gaming controller in China with an attractive price tag. Thanks to the introductory promo, it is currently available to buy on JD.com at CNY 559, which converts to around $77. This pricing makes it an affordable alternative to the popular Backbone One game controller, at least for the Chinese market.

As for the main highlights, the new GameSir X4 mobile gaming controller focuses on high playability. It comes with Microsoft authorization, making it a perfect option for streaming Xbox Game Pass titles through the phone. Also, it is compatible with many popular mobile games such as Genshin Impact, CoD Warzone Mobile, and PUBG Mobile.

One interesting aspect of the mobile game controller is that it can be detached into two controllers. This will allow a Nintendo Switch-like offline multiplayer gameplay. Thanks to the replaceable buttons, mobile gamers can even swap the layout and modify the GameSir X4 according to their preference.

On that note, the mobile gaming controller features Hall Effect joysticks. These promise higher accuracy than regular analog alternatives. The GameSir X4 also has Hall Effect triggers and features a customizable dead zone. That offers the freedom to change the trigger sensitivity.

Besides that, GameSir says that the microswitches have a lifespan of 5 million clicks. It also uses Game X Link wireless architecture, which offers multiple connectivity options. Of course, if you want the lowest latency, you can use the USB-C connector and attach the game controller directly to your phone.

Speaking of which, the GameSir X4 can fit on mobile devices that are anywhere from 68 to 95 mm in width and up to 12.5 mm thick. Other highlights include RGB lights on the joysticks and textured grips for added comfort. Global availability hasn’t been announced yet, but GameSir did bring its past releases outside China (GameSir X2s curr. $45.99 on Amazon).
