The first thing that jump eyes water: the color! it flashes! it feels good, a headset that colors so sad to cry ... However, on to what matters: 1) ease of coupling with the notebook: excellent! 2) comfort: excellent: at the start, we said that the headset will never hold, but in fact, it holds very well without difficulty and without forcing. It is super comfortable! 3) its nickel, fault (obviously, when we remain in the same range of product and price ...) 4) THE most to me: I had a headset that only allowed to call. This one also makes listening to music, I'm thrilled!
