Any pair of Bluetooth headphones or speakers will work, the sound quality is excellent (not as good as a high end cord headset) but perfectly acceptable for the purpose.
I use a dual stream Bluetooth adapter on my Tablet, it allows you to use 2 Bluetooth headphones simultaneously from one device. It plugs into your 3.5 audio outlet.

You can use any bluetooth headset with any TV with an bluetooth receiver.
