A:AnswerHello Nickblue, To stream you'll need WiFi, you can connect via coaxial to watch you Xfinity content but you can also download the Xfinity Stream app off of the Roku App Store. https://channelstore.roku.com/details/8d6f3245be847d75357a9e4e9db22c80:0838d6365c0fe48e12d28c5055da82d5/xfinity-stream
A:AnswerHello Jon, the Bluetooth off of the TV would allow one headset but you can use the Roku mobile app’s headphones mode and have 4 more headphones at one time.
A:AnswerHello joed, Yes there is a sleep timer. To set a Roku sleep timer, navigate to Settings > System > Time on your Roku TV and select the desired time interval.
