I think the trick with the standard headphones is to get the right size of rubber cover on the ends. Too small and they are a loose fit - too big and they do not push far enough into the ear to be secure. I started on the biggest size "bung" and had issues with it falling out. I am now on the smallest size and the fit is very secure but putting them on and taking them off takes longer as they fit quite deep and secure within the ear - almost like fitting industrial ear bungs. It does have the added benefit of improving sound quality and reducing any ambient noises but quite "hard work"
