NB10s slide out of ears when running causes sweat

Love my NB10s…the sound of great and they fit pretty will until about 15min into a run when my head starts to get sweaty. My NB10s predictably lose their seal and eventually lose all my bass and they come out of my ear. I have tried adjusting strap on the back and trying all 3 sizes but to no avail. Is there a trick to this that I’m missing? Thanks in advance

I use tri tip eartips for this reason if I’m working out. I know I get really sweaty so using the tri tip eartips I can insert them into my ear more for an even better fit…I also don’t have to have the volume as high so that’s an added bonus.

I used to use these on my UrBeats. They work a treat.
