The easist way would be to plug it in to the headphone out on either device.
Alternatively you can pick up a BT transmitter. Most will be cheap chineseones with undetermined quality, but if you search on this forum a couple of people have already suggested some. Just be aware many will have lag between what you see and what you hear. Most branded TVs are starting to get better with thier internal transmitters, but even a TV brought 2 years ago would likley have audio lag with BT headphones.
