They do not specify in the product info section which I have contact them and complained about BUT They seems to be the 2019 edition base on the following:
Googling the model number it compares with other website stating 2019 edition
Same goes for the UPC number when googling it.
Plus comparing the appearance such as headband rubber part and art design and also the rounder bend in the steel headband.
But sadly no full confirmation from Best Buy yet.
