bought one and now just bought another since I?m so pleased with themson (my son uses the first pair) Even cheap earbuds are sounding more like the high end versions costing hundreds of dollars. Its a little clunky feeling to handle, but still light enough that its comfortable and doesnt seem to want to fall out. 5mm que traen los headsets desconozco si se puedan usar via bluetooth igual llevar los con el celular bajo el sol no lo recomiendo mucho y la otra cosa que me gusto mucho de este modelo es el botón que trae para ajustar el volumen del chat de juego (discord,skype,ventrilo,etc) con el volumen de la pc o el juego que estés jugando en ese momento, es mejor que estarle moviendo a las opciones de auido del juego o la pc para poder escuchar mejor el chat o al revez, bajale al chat para escuchar mejor el First thing I noticed is the nice cushioned support and soft, wide strap material. They are so small that they are unsuable. I organize closets and more for a living and these are absolutely amazing. I love love love this product. AKGs have mids-forward sound, Sennheiser has the infamous mid-frequency V, for example. I simply plugged it in and tried it on, listened to some music and talked with some friends.
