Earbuds never stay in my ears for more than a few seconds, especially when I try to use them while walking, running, exercising, and/or I start sweating, etc. The same goes for any type of headphones that are partially inserted in the ears with no other support. I can only use headphones that have some type of looping feature that goes completely around the lobes 360 degrees. If it’s an open loop, those fall out too.
