JSAUX is expanding its portfolio under the gaming sub-label VOIDJOY with two new controller products set to launch just in time for IFA 2026: the SkyLark S1 Pro, a compact, multi-platform portable controller, and the Elite Extender, an attachment for the Nintendo Switch Pro Controller. Both products have been available via JSAUX.com since September 1, 2026.
JSAUX and VOIDJOY: The Controller Market as the Next Step in Growth
JSAUX launched in 2016 as an accessories manufacturer and became known primarily for its high-quality Steam Deck accessories. With VOIDJOY, the company is now venturing into the significantly more competitive controller market. This market is already home to long-established specialists such as 8BitDo, GameSir, and GuliKit, all of which rely on Hall-effect or TMR technology to solve the widespread stick drift problem. JSAUX consistently follows this approach with the SkyLark S1 Pro. The focus on the Nintendo Switch 2 is strategic: Following the Switch 2’s launch in 2025, demand for compatible third-party accessories has skyrocketed.
VOIDJOY SkyLark S1 Pro: Portable Controller with TMR Sticks
The SkyLark S1 Pro is a compact controller for on-the-go use. It connects via 2.4 GHz wireless, Bluetooth, or USB-C and supports Windows, Nintendo Switch, Nintendo Switch 2, SteamOS, Android, and Apple devices. PlayStation 5 and Xbox are not supported.
Technically, JSAUX relies on retractable TMR (tunnel magnetoresistance) sticks with magnetic sensing—a method that is said to be more drift-resistant and durable than potentiometer sticks, which are prone to manufacturing variations, and keeps the controller more compact.
The optical triggers can be switched between Analog Mode (full pressure sensitivity for racing games) and Quick Mode (short trigger travel for shooters). A single 2.4 GHz receiver can connect up to two S1 Pro controllers simultaneously. Using the KeyLinker app, users can customize button mappings, configure macros, and install firmware updates.
Price: $49.99. EU availability is not planned for launch.
VOIDJOY Elite Extender: Upgrade for the Switch Pro Controller
The Elite Extender is not a standalone controller, but rather an attachment that mounts directly onto the Nintendo Switch Pro Controller—without the need for disassembly. It adds rear P1/P2 buttons, removable linear triggers for analog input in racing games, and a built-in 1,800-mAh battery for longer gaming sessions.
It is also configured via KeyLinker. The concept is similar to that of the Xbox Elite Wireless Controller Series 2 or Thrustmaster’s eSwap controller—only as a retrofit upgrade rather than a standalone premium product.
Price: $39.99.
Outlook: VOIDJOY PC Controller Coming Later in 2026
VOIDJOY has also announced a modular PC controller set to launch in 2026. With this move, JSAUX is setting its sights on the PC gaming market in the long term—a segment currently dominated by the Xbox Elite and Sony’s DualSense Edge. Details about the PC controller will be announced separately.
JSAUX at IFA 2026
JSAUX will be at IFA 2026 in Hall 7.2b, Booth 117. In addition to the VOIDJOY products, the company will also be showcasing its Steam Machine faceplates and other gaming accessories there.
Conclusion: A Solid Entry into the Controller Market
With the SkyLark S1 Pro and Elite Extender, JSAUX is entering a highly competitive market, but it brings relevant technology to the table: TMR sticks, switchable optical triggers, and broad platform support are strong selling points. The lack of EU availability at launch is a downside. Anyone interested in gaming accessories should also check out our Steam Deck Accessories Guide.
