Bluetooth headphone connection to Samsung tv

[s99ane]

I need a bit of help here.

Current setup is Samsung ue55d8000 tv

Yamaha yap 2200 soundbar

Also connected apple tv2, ps4 and vi solo box.

I want to watch movies or game at night after baby has gone to bed. I would like to be able to connect my sennheiser mx400 but can't see how to go about it.

Merry Christmas PH
