Its pros: Sound with a good amplifier. A set of cables and the possibility of replacement: 3 pcs, 1 short 1.5m, 2 three-meter, spring and simple. Reliability of fixation. Folding, in the "transport" position are compact. Good wear resistance: before that there were senheisers for $ 100, after six months of everyday use for about 4 hours, the ambichurs and the headrest cracked and became generally terrible, these have more than a year and a half, with constant traveling (senhi did not take with him, did not fold) a couple of cracks, barely noticeable on the ambichurs, the headrest has not changed. Ambishur replacement. And most importantly, they are comfortable, unlike other "monitor" ones, in which, after an hour of wearing, the feeling is that the head is in a vice, a minus, probably for DJs, but for domestic use, the most ice. Cons: Without an amplifier, it makes no sense to take it, there will be no sound, I tried it from the yamaha 677 receiver (although they write on it what is on the ears), from the computer directly, from the laptop, everything is nothing. Normal sound card or a separate amplifier / player with a good amplifier.
