How can I connect my rf headphones to soundbar when streaming music from my phone via bluetooth to the soundbar? The soundbar has available portable in, usb, and HDMI in. The RF headphones are connected to the audio out of a sky box by rca plugs and work great with the tv and video player.
Soundbars don't have audio outputs so there is no way to connect the RF transmitter for your headphones to it. Fortunately that's not necessary since you want to listen to the phone not the soundbar.
What you can do is connect an audio input selector switch to the RF transmitter so you can chose to listen to the sky box or a bluetooth receiver that can pair with your phone.
