GameSir X2s Type-C mobile controller review: retro design, modern performance

One-minute review

The GameSir X2s Type-C is a mobile controller that costs less than half the price of the Backbone One or the Razer Kishi V2. Despite this, it still manages to offer a comfortable gaming experience and plug-and-play compatibility with all major game streaming platforms and a wide selection of native mobile titles including Genshin Impact and Call of Duty: Warzone Mobile.

Its retro Nintendo 2DS-inspired aesthetic is charming and, while the plastic used across its construction feels cheap and hollow, the satisfying clicky buttons and Hall effect thumbsticks and triggers are excellent – and features that you’d normally expect to find on some of the best PC controllers. These controls not only feel great but also perform well no matter what kind of game you’re playing. The adjustable Type-C connector is itself a brilliant innovation, greatly reducing the frustration of trying to cram a phone into a retractable mobile controller. It simultaneously ensures compatibility with most phone cases, removing one of my biggest gripes with the Backbone One.

The lack of a headphone jack might be a deal-breaker if you intend to play with a wired pair of any of the best gaming earbuds, for example, but the GameSir X2s Type-C is otherwise an extremely compelling mobile controller that undercuts the competition with a great value price.

Price and availability

• $45.99 / £49 / AU$69
• Cheaper than the competition
• Widely available

The GameSir X2s Type-C is readily available via Amazon in the US, UK, and Australia for $45.99 / £49 / AU$69. It can also be purchased directly from the GameSir website, in addition to an official store on AliExpress. Although frequent discounts are available at AliExpress, you will have to contend with longer shipping times if you go with that option.

Even at full price, however, the GameSir X2s Type-C comes in considerably cheaper than its competition – namely, the Backbone One, which costs $99.99 / £99.99 / AU$179.99, and the Razer Kishi V2, which is $99.99 / £99.99 / AU$169.95. This positions it firmly as a budget alternative to these two controllers and, while it is lesser when it comes to overall build quality, it nevertheless offers excellent value for money.

Specs

Design and features

According to GameSir, the design of the X2s Type-C mobile controller was inspired by the appearance of the Nintendo 2DS. This is evident in the purple hue of its buttons, which are strikingly similar to buttons found on the White and Lavender Nintendo 2DS XL. Despite these surface-level similarities, however, the GameSir X2s Type-C actually shares a lot in common with most other mobile controllers. 

Firstly, it features a spring-loaded back, which can be extended to accommodate a phone up to 6.6 in / 168 mm tall. While the extension mechanism operates considerably less smoothly than the one found on the Backbone One, producing quite a rough sound, the controller still fits snugly around most phones and feels very secure once everything is in place. As the name would suggest, the controller connects to your phone through a USB Type-C connector, so is only compatible with the iPhone 15 series or Android devices that feature the port. 

On top of the ability to extend the controller, the GameSir X2s Type-C can accommodate an impressive range of phones thanks to the unique moveable nature of its Type-C connector. Unlike the fiddly, static connector of the Backbone One, the connector here can swivel both towards and away from the rest of the controller. This is a fantastic innovation and something that I believe should now become standard across all mobile controllers given just how much it improves the experience.

The added flexibility makes it far easier to attach or remove your phone safely, completely eliminating the risk of damaging your USB-C port or the controller itself if you pull your device away at an angle. It also means that the controller can be used in conjunction with a thin phone case, which is a welcome change. I find that having to remove my case to attach the Backbone One is inconvenient, leaving my phone exposed to potential damage.

Like the Backbone One, the rest of the GameSir X2s Type-C is effectively just two sides of a traditional controller that flanks your phone. There are asymmetrical thumbsticks, a d-pad, a set of face buttons labeled in the Xbox Wireless Controller layout, a screenshot button, a home button, two triggers, and two shoulder buttons. Rather than the conventional ‘Start’ or ‘Select’ though, each side of the controller has either a ‘G’ or ‘S’ button which performs those same functions.

A set of four thumbstick covers is also included in the box. These can be slipped onto the tips of the thumbsticks to give them a slightly larger surface area and a more tactile ribbed finish. Although I didn’t find the need to use them, it still makes for a neat little pack-in bonus.

You can then further customize the feel of the thumbsticks via the GameSir app, which allows you to tweak a range of settings. This includes thumbstick dead zones, trigger actuation depth, or even a toggle to switch to a Joy-Con controller button layout. In addition to a catalog of other GameSir products, there’s a tab containing a handy list of fully compatible mobile titles, with links to the relevant App Store, which could be a great way to source recommendations if you’re wondering what to play.

A Type-C charging port is located on the bottom of the left-hand side of the controller, allowing you to charge your phone while it’s in use. Two small LED lights are present on the right-hand side too, with one illuminating to show when it is connected to a phone and the other indicating whether your phone is charging. Despite ample space, there’s disappointingly no headphone jack to be seen anywhere.

Performance

When I took the GameSir X2s Type-C out of the box, my first impressions were mixed. There’s no avoiding the fact that the plastic used on this controller simply feels cheap in the hands, especially compared to the likes of the Backbone One or Razer Kishi V2. Sure, these are much more expensive controllers, but the hollow-feeling grips of the GameSir X2s Type-C undeniably detract from the experience. Even the rubberized pads that cover the rear of each grip feel cheap, being far too hard to offer any real cushioning. My model also sported quite a few prominent manufacturing seams that tarnish the otherwise clean purple and gray aesthetic.

Still, once you have a phone slotted into place it’s hard to fault the GameSir X2s Type-C in any other areas. Although the thumbsticks are smaller than a standard gamepad, they offer a generous level of motion and feel substantially more precise than the awkward, stubbier set found on the Backbone One. Likewise, the triggers are a very comfortable size and operate responsively. Better still, both the thumbsticks and the triggers make use of Hall effect technology, which should enable them to last considerably longer without developing dead zones or drift. 

The micro switch buttons are well-spaced and pleasantly tactile, with engraved lettering like the buttons of the Nintendo 2DS. Similar micro switches are then used in the d-pad, which is a comfortable concave shape. The shoulder buttons are then large, responsive, and produce a very satisfying mechanical click. It’s an excellent set of controls, only further elevated by the fact that every single game I tested worked flawlessly with no tweaking. The native mobile version of Vampire Survivors felt just like I was playing on Nintendo Switch, while my K/D ratio in online Call of Duty: Warzone Mobile matches benefited hugely from the pinpoint accurate thumbsticks and triggers.

This strong performance carried over into game streaming. Jumping into some Far Cry 5 and a fair few matches of Fortnite on Amazon Luna, the controller was instantly recognized by the web app, and the correct controller prompts were automatically displayed. Likewise, Xbox Cloud Gaming via Xbox Game Pass Ultimate was a treat with Halo: The Master Chief Collection, Forza Horizon 5, and a handful of other titles playing wonderfully. If you’re searching for a budget-friendly mobile controller that’s perfect for cloud gaming, few perform better than this.

How I tested the GameSir X2s Type-C

• Tested for over 15 hours
• Tested with both native mobile titles and game streaming
• Compared to other mobile controllers

I used the GameSir X2s Type-C for over 15 hours with a Samsung Galaxy S23+. During that time, I tried a selection of popular native mobile titles including Call of Duty: Warzone Mobile, Vampire Survivors, Diablo Immortal, Minecraft, and Genshin Impact. I then used the controller with multiple game streaming services, including Xbox Cloud Streaming and Amazon Luna which I used to explore a wide variety of available games.

As an avid mobile gamer, I also directly compared my experience with the GameSir X2s Type-C with the Backbone One and Razer Kishi V2 in addition to other mobile controllers.
