does not retain thinner cable. ” “Splash! The charger itself is a little bulky, so maybe not great for travel. To be clear, both did hurt the same but both did a very good job. Had them sitting new in the box until February of 2018 as I unexpectedly given new shoes. Only thing, I needed them for boat shoes, to safely walk on the deck of a sailboat on the open ocean,,, for this, they are no good. The cross bars are clearly marked to help in placing them properly and they take about 10-15 minutes to install - nothing too complicated and doesnt require special knowledge or skill. I sent them back and got a new pair and they were still the same length. I was really excited about having these headphones cause I love new toys. Highly recommend both the shoes, as well as amazon wardrobe!
