Have a cable box, do I connect to cable box analog outlet or direct to tv? Tv is not a smart tv.
A shopper on Mar 6, 2023
  Thanks for your inquiry. The RS 120-W transmitter should be connected to the TV headphone jack or analog audio output jack.
Having trouble pairing to tv?
A shopper on Mar 6, 2023
  Thanks for your inquiry. The RS 120-W connection between transmitter and TV is a wired connection. The transmitter connects to TV analog headphone jack or TV analog audio output. Once plugged in and turning on the headphones, the wireless connection is very straightforward. Unlike a Bluetooth wireless connection, the headphones immediately connect when turned on. The included owners manual provides detailed instructions and illustrations, including instructions for installing two AAA size rechargeable NiMH batteries.
