Mine developed a crack after about 5 months. I called HP to get a replacement and they sent a new one the next day. When I asked what to do with the old ones, they told me to toss them. Now I have 2 pairs of headphones for the price of one

. I got the toshiba USB bluetooth adapter and had to do some finiking with the driver, but now my second pair works with my work PC. Even all the buttons work in Windows Media Player 10. I can pause, play, even launch applications with the action button, and next/previous track stuff. Works amazingly great.
