The index has a headphone jack, yes. But with the default face gasket it can be a bit finicky for bigger plugs to fit, so get a smaller cable.
If you can find low-latency wireless headphones (so NOT bluetooth), I think that might be a better option as you don't have to fiddle with extra cables. Sennheiser has a few good ones that have like a station you plug into your PC.
