No matter what earbuds or earphones I use when running, they will just randomly cut out and go silent at times, then come back. I try to vary my cadence (I wear an armband and put the phone in it, then attach the headphones to that) but whatever happens, it kills the sound and there's tons of static sometimes. Some days it's not as bad.
I've tried using canned air to clean the 3.5mm headphone jack where they go in but it doesn't always work, plus I've tried different headphones, from Beats to cheap ones at DG, and Apple earbuds.
Does anyone have a solution? My next step is to pony up for Bluetooth wireless earset.
I use the basic Music app that came with my LG G6 and run my songs that way.
Another annoyance--when I run Google assistant will randomly interrupt me and tell me what time it is even though I figured out how to disable it from settings otherwise.
