SHOKZ openmove vs openrun

Hi everyone!

I was looking to get a pair of shokz because they’re on sale right now. I saw the openmove is half the price of the open run. I was looking for some guidance on if there’s any reason why I should buy the openrun’s over the openmove. The main thing I care about is the fit on my head. I don’t really want it to be able to bounce around at all as well as the battery life! Hoping I can get some guidance!
