Absolutely loved this series. Ive purchased at least a 2 dozen headphones over my life costing anywhere from Walmart cheaps to Sony studio monitors ( Im older so back in my day those were like the best especially if you had an analog music source) and I have to say for what I paid for these? I couldnt be happier. There is no stiffener in the bottom. Bottom line is, if I had normal feet that were average or narrow width, I think these might have been comfortable after a short breaking in period. I got xl for my son who has just turned 12 and is 5ft and the hoody fits him well! That said, the app does make it easier to access many of the features, since you do not need to press key combinations to change these settings. Its also a bonus that it included a small clip to attach to your cord to your shirt, Dr. Wie immer Passform garantiert. I had to readjust the cord by unplugging and replacing the plug just to get sound in both ears (A regular aux cord can do this effortlessly). If there is any problem, I will update this review.
