Bluetooth 5.0 Transmitter and Receiver

I was hoping to use this to create the flexibility for my RCA to to connect via blue tooth to my sound bar and switch to my Bluetooth headphones at times but the sound quality when used with the sound bar is poor. When I connect the tv to the sounbar with an optical and hdmi cable you can get all the details in the sound. It's louder and much more bass. For the headphones to work I have to unplug the sound bar as it connects to the sounbar quickly. In this case I wouldn't go through all the trouble to switch do will find some other use for it.
