I've had this model headphone since 1998. It is the best headphones I have owned compared to all others. It doesn't hurt your ears and allows to breath when you work out. Cord doesn't tangle easily. Freq responds good, also can hear when people are trying to talk to me. I have taken these to Afghanistan being that I'm military. I have used it 3x -4x weekly going on 10 years now. I am buying an extra set in case they stop making them.
