A:AnswerYes there is an optical audio input or if your sound bar is bluetooth you can connect it that way with no wires except the power to the sound bar itself.
A:AnswerYes I do have a ZVOX sound box because I listen to a lot of music and sound is very important to me. However the sound from this TV is decent and you may be satisfied by it. Within the settings for sound you have several options for how sound is delivered. You can also add a sound bar or box.
A:AnswerThe answer to your question regarding an 800X400 VESA mount for the SONY XBR49X900F LED SMART 4 is NO. that VESA configuration is not mentioned in the specs..
I went to the Sony Specifications page at

The VESA hole pitch from that page only describes 2 VESA configurations VESA® HOLE PITCH(W X H) 7 7/8 x 7 7/8 inch / 200 x 200 mm
A:AnswerI successfully paired my 3 year old Bose SoundLink headphones to our new Sony XBR49X900F. The tv automatically found the headphones once they were set to pair with it.
