Boise headphones
Can you connect headphones into the sonos or system? How would that work? Would it mute sound bar automatically? This is how my husband watches TV if I'm sleeping.
Not sure about into Sonos .. no visible jacks. However, if you add ROKU 3 or 4, they have an earphone jack with volume control and when watching a Roku based channel, the earphones turn off the TV's speaker and the Sonos as well.
