Arrived extremely quickly and in perfect condition. So far they have worked great.
However - the Bluetooth device list was not cleared, and the headphones were still paired with an unknown iPhone from their previous owner. Also, there were internal settings changes that had not been reset that I had to fix using the Bose app (namely, the automatic shutoff feature was set to 5 minutes, when the default is Never). I had no problems fixing these issues, so I'm still giving 5 stars. However I found these oversights highly unprofessional and would urge the distributor to put more effort into making their products a 'blank slate.'
