You have INs and OUTs on your TV and other devices. Sound is coming OUT of the TV and Into the device you're connecting - your bluetooth speaker or your bluetooth Beats headphones for example. SO, if you want to send audio FROM a phone, tablet, or device to your bluetooth speaker or Beats headphones, you can. But one or the other. Same with sending sound OUT of your TV into your speaker or your headphones, but only one at a time. To connect your Beats headphones to your TV, you can do that 2 easy ways. You can connect your Beats to your TV via bluetooth if your TV is bluetooth enabled. If not, you can connect a bluetooth receiver to your TV via an HDMI cable or an optical cable. Then you would pair your Beats headphones to the bluetooth receiver so you can listen to your TV through your headphones.
