While working on "Our Story" we compiled a huge photo record of Koss products. Below we put our doodling skills to the test, highlighting some of our favorites. We doodled some of our favorite products from 1958-2015. See details of each frame on our blog. #TBT #Koss A video posted by Koss Headphones (@koss) on Feb 11, 2016 at 1:20pm PST
