A:AnswerNo, these cannot be connected to a sound bar. If you have something like a Roku connected to your TV, you can connect these headphones to a phone or tablet and use the Roku app on that device to control your TV. It will also allow you to hear sound through these headphones if you want.
A:AnswerHi DougS, these headphones can be connected to devices that support Bluetooth headphones but dual audio capability will depend on the iPad's specifications. It must have the option to allow output from the iPad's speakers and headphones at the same time. ~Ralph
