Bluetooth connection between headphones and watch constantly drops while running

Have not found anything recent that is my exact situation so posting in here. I have a Venu 2 watch that I have downloaded both owned music and YouTube Music on to. I have Galaxy 2 Pro Earbuds. When trying to listen to music when running, the connection is dropped constantly. on a 3.5 mile run, the connection dropped four times for no apparent reason. Only way to reconnect is to stop running, and go through the Venu music menus = Music/headphones/GalaxyBuds2/Connect and the headphones will connect to the watch again. I do not have any issue with the earbuds dropping with any other device. THe connection drops whether I'm playing owned or downloaded streaming music. Really a pain to have to stop to reconnect several times during a run. Thanks for any assistance anyone can provide.
