headsets

My PC, PS3, and Cell are all Bluetooth enabled, but I want to know if those Bluetooth headsets for cell phones work with other devices as well.

I've been looking into getting another headset (my puppy decided to make a chew toy out of my last one). It wasn't anything special, cheap generic brand one, couldn't even say which it was. Was looking for opinions on some good headsets, what to avoid, etc. I've had a few, never spent too...
