EXCELLENT QUALITY AND GREAT SEPERATION. Even though this set arrives with mounting hardware, I STRONGLY recommend using the kind from the hardware store that supports much more weight. (Make sure you are using the correct audio channels. La diferencia de este modelo es la suela color crema que rompe con el total White y que en mi opinión queda genial y el detalle de detrás, en lugar de ir de otro color hace un efecto en la piel que queda muy original. Ill update if the unit craps out or something, but I have no reason to expect that will happen. The material feels nice and warm. It is also nice to have the Bose 700 connected to both my PC and my iPhone at the same time. They?re pretty cute and well priced if your size happens to be lower priced. Ive said Im going to return these and would like a replacement so hopefully theyll actually get it right and send me two 3x shorts. It?s possible to find the sweet spot, but you need narrow ears, a narrow head, and a bunch of finicky trials to make them fit nicely comfy.
