This is more of a general question about Bluetooth, but it applies to the Z1 too. Can anyone else hear static either using the Z1 Bluetooth or Bluetooth headsets in general? I just got my first Bluetooth phone (Samsung A940) and tried pairing it with a friend's new Z1. There's static in the background on calls, and it does the same thing with my Jabra headset. His Samsung A920 has the exact same static. It's not terrible, just a bit annoying.
Is this normal with Bluetooth?
