Bought these the last time when they were up. They sound great and no problem paring them with a Windows 7 notebook or Ipad, but they are both, too tight to the point of being uncomfortable, OR, if I'm wearing them while I run, the bouncing of the headset causes there to be a loud clicking as the earpieces break contact again and again with my ears. So, they are both too tight and too loose. I'll try wearing them upside down as many suggest and see how that works. I think they may just be a bad physical design. I have some Motorola 305s (outside ear) which work great and have great range, but which are also tough to run with. It's not the technology, it's getting the bluetooth electronics into a package that is light, secure, and can withstand exercise movement.
