A:Answer the supplied 3.5 mm stereo mini-pin cable plugs into and connects the the wireless transmission/headphone charging tower to the 3.5 mm headphone port on the TV. HDMI does not provide any connection to the headphone tower. However, if your TV does not have a 3.5 mm headphone output port, but does have HDMI output or Optical/Digital output, connected to an AV stereo receiver with HDMI and/or Optical/Digital input on the rear and a 1/4" headphone port on the front, you set your receiver input to either of those choices and then insert a 1/4" to 32.5 mm headphone jack into the front port and then one end of the supplied 3.5 mm stereo cable into that and the other into the input port at the base of the transmission/headphone charging tower. turn everything "On" and you have wireless headphone access to TV/TV apps, or Youtube, or Spotify or Netflix from your computer/internet, if you can connect your computer to the AV receiver, usually from a soundcard connection(Optical/Digital or RCA).
