There isn't right now. The controller does have a Bluetooth chipset in it, but it isn't enabled yet. Given that bluetooth headphones often have fairly large issues with latency and AV Sync I would probably not plan on relying on this even if it ever does gets enabled. You'd be better off using a wireless headset that has a transmitter that plugs into the USB Port, but that isn't yet enabled either - hopefully USB headset support comes sooner than later, I'm waiting for that to roll out myself.
Correction: since update, usb headphones are now supported (but still not wireless if you play through chrome cast)

I found a way for bluetooth headphones to work with almost zero lag. Here is my YouTube video on it.
