Unfortunately, you can't connect Bluetooth speakers to this TV. You can connect a wired sound bar, home theater sound system (receiver and speakers) or wireless headphones with a wired based station (RCA or digital audio input from the TV's audio out). These wireless systems use RF or Bluetooth signals to the headphones. See this page,
http://stereodevelopment.com/#what-are-wireless-tv-headphones , for a few models of wireless headphones that will be compatible with the D43-D1.
I wish that I had better news for you. You may be able to find an audio receiver that supports Bluetooth. However, these usually are Bluetooth devices, the same as the Bluetooth headphones. They can't pair and send a signal to your headphones.
