I am using Jaybird blue buds BT headphones...never had a connection problem until the watch. I've listened across my apartment (15ft) to my phone with the headphones and never dropped signal. I've also run on the treadmill connected to my watch and never had a problem. When I run outside however the connection is very spotty. Not really sure why as my hands are roughly in the same location running outside/on the treadmill. Anyone else have the same issue?
