Query: 7 Years Worthy!

I've own a pair of PX-100's since 2002. For under $50, these are great headphones! Very light weight, and I've used them constantly for the gym. I am use to using audio gear of much higher caliber, but these are just awesome headphones! Perfect for the gym, or subway, or walking. They are open-type so you can hear outside, but it only leaks just a bit. I bought a second pair a year ago since I lost my original pair, but my original pair lasted 7 years of gym, working, etc... and no damage. They do seem fragile at first, but they can handle it. I can't say enough good things about these speakers. Yes, I use better headphones at home with an amp, but it's hard to beat these for great music and portability with an Ipod/MP3 player.
