No sorry. The last Bose to come with the adapter was the QC35s (series I), The QC35IIs did not! Bose stopped adding them. The 700s appear to NOT be designed for Airplanes, Trains and other LONG rides where as the Comfort (in Quiet Comfort) is lacking. So Bose has no need to add that adapter in these like they should have in the series IIs.. The 700s were not to replace the QC35s, they are another addition to Bose. Just think of the 700s as the “coffee shop”, I like to talk on the Phone type ANC headphones.
