Very easy to use! I bought a cheaper knock off replacement cable off another seller and no matter what adjustments were used, the mic would echo in party chat. Por ejemplo que no enciende o no vuelve a tirar luz, pero no es así! Overall, I recommend them (and some sea-noise) if your neighbours are keeping you awake. Se sienten de calidad, más a pesar de estar usando calcetines polares bastante gruesos, quedan algo grandes, Nada del otro mundo, más a tener en consideración si desean que queden a la perfección. The HD 660 S is incredible. I gave this to my girlfriend for her birthday and she loved it. But I put up with it because by nelly I had paid a hundred bucks for the darned things and I was going to wear them. They are nice and soft. Doesn’t feel like a DIRT game whatsoever.
