I have two Bose QC35 in Black and Silver. Both purchased in USA from Dell on 26th August 2016 and comes with electronic receipt in email.
Hardly used - Black was actually opened and used once to test and that's about it. Always had both of them in the hard shell box that came with it.
Comes with everything that came in the box apart from the Actual box itself which i thrown it away long back.
We only opened them early this year after our trip last year to USA.
Selling as we no longer use them. Pick up flat bush or I can meet in city during working hours.
Price $350 firm on each.
