I bought the Jaybird Run when they came out and had them paired to my iphone while running. Didn't have any issue with bluetooth drop outs. Love the headphones, sweat resistance with no wires. Bought the apple watch 4 so I could run without the phone. I've paired the Runs with the watch and the bluetooth signal is awful. Unless I hold the watch out in front of me and keep my head perfectly still, they cut out. Normal arm sway or moving my head at all causes the connection to cut out. Anyone else have this issue? I can't believe this is normal.
