I have a vizio model s4251-b4 soundbar and am looking for a set of bluetooth headphones that will pair with it. I am a novice but i was able to get the soundbar to pair with my iphone and ipad. i don't understand why my lg bluetooth earbuds will not pair with this bluetooth soundbar.
I know this is a really old question at this point, but maybe it will help somebody, who knows.
If you buy a pair of wireless headphones that have a receiving end that plugs into a headphone jack, you plug that receiver into the back of the sound bar to get the audio to your headphones. The one downside would be that you would likely have to remove the receiver from the audio jack in the sound bar every time you wanted sound to come out of the soundbar itself, as opposed to your headphones.
So it's not really a practical answer. But it technically would work.
