I found these on sale at the local Office Depot , they only cost me 200 pesos (15 Dlls) , they do sound nice but unfortuanely since they have a 300 ohms impedance they dont produce much volume with PMPS, when you switch the cancellation on it does improve sound and Raises the volume level, The battery pack is huge and always gets in the way , but i would give them a 7.5 out of 10 because they do sound and look good (i am only giving it 3.5 in design because of the battery pack) just dont expect to be using them on flights without a portable amp.
