A runner's question @ Bluetooth stereo headset with 7th gen nano?

I'm looking to buy a JayBird or Jabra or other Bluetooth stereo headset while out running. I've heard and read that reception can be poor while using previous players with BT. Has anyone used the 7th gen nano built-in Bluetooth successfully paired with a stereo headset? If so, was reception good and clear and where did you have to place your nano on your person?
