Free open-source tool turns Sony headphones into a head tracker for 200+ PC games

A Reddit user going by NSlattery43 has released free, open-source software on GitHub that lets Sony headphones and earbuds double as head trackers for PC games — no webcam, no infrared sensor, no extra hardware required.

The software grabs live orientation and gyroscopic data from compatible Sony devices and pipes it into OpenTrack, the established head-tracking middleware that already talks to a huge library of games. Because it outputs via OpenTrack, it works with any FreeTrack-compatible title as well as games that support TrackIR — a list that covers over 200 games including Microsoft Flight Simulator, Elite Dangerous, and Assetto Corsa. Confirmed compatible hardware includes the WH-1000XM5, WF-1000XM5, and ULT Wear. The Sony Linkbuds lineup — WF-L910, WF-LS910N, WF-L900, and WF-LS9000N — hasn't been tested yet, but Slattery says Sony's own spec sheets list the right head-tracking modules, so they should work. Setup is straightforward: download from GitHub, pair your Sony device, launch the app, then run OpenTrack alongside your game. If the tracker node fails to register, there's a built-in option to force it.

Sony's WH and WF series headphones have always packed motion sensors to power the company's spatial audio head-tracking on PlayStation and in Sony's own apps, but on PC that hardware has largely sat idle. OpenTrack itself is a long-running open-source project that supports a wide range of input methods — from IR clips to webcam face tracking — so plugging Sony's sensors in as just another input source is a clever use of existing infrastructure. One community commenter pointed out that pairing the software with XR glasses in display mode could deliver full 360-degree 3DoF tracking with no controller needed for looking around, which is a compelling setup for sim cockpits in particular.

Sensitivity and input curves are customisable, so you can tune it to behave more like gyro aiming — sharp snaps for quick looks, fine control for precision — rather than a raw 1:1 head mirror. Since the code is open-source, anyone can fork it, extend compatibility, or tweak the pipeline. For anyone already owning a compatible Sony headset, the barrier to entry is essentially zero.
