They are very comfortable from the moment you put them on! I am picking and have a hard time finding shoes that fit well and are comfortable. well it worked great for awhile, then it wouldnt charge. Buy at LEAST a size up. With 3 months of wear, they have shown a couple of loose threads, but they seem like they will last a very long time. Andernfalls hört man ständig ein leises Dauerbrummen wenn die Maus geladen wird bzw auf dem Pad liegt oder dumpfe Intervalle wenn die Maus ausgeschaltet ist. Also they were used and had been worn before. I did try in the actual sound card built in still no 7. I really wanted these to work; Ive looked for a well-cushioned shoe for a long time. Turn up your earphones even when the volume on your device is all the way up (I was lost at first on why the volume was low).
