A:AnswerYes. It also has an Ethernet port so you can connect either way. Comes with Netflix, Amazon Prime, Plex, YouTube, etc alreadu installed and ready to roll too.
A:AnswerYes, BUT... from other posts I've seen (unless they just didn't plug it in properly), the headphone jack MAY be a monaural output (all sound put into 1 channel), not stereo (separate info from 2 channels), like MOST stereo headphones want to reproduce.
If true, and to get sound to BOTH of your STEREO headphone speakers, you MAY need a "stereo to mono" (way cheap @ Best Buy, Radio Shack, etc.) adapter.
