Trouble with musical randomly stopping,

[theusernameiwan]

Hello,

I use an iPhone 6s and I utilize the following bluetooth devices simultaneously Headphones, Smartwatch (over bluetooth le), and a medical sensor. Occasionally music will randomly stop. The music is downloaded as I have premium. Either the music stops and sometimes (very rare) the signal to the headphones will sound choppy for a few seconds. Does anyone have an idea on why these things happen?
