Sorry for the late response Lee pretty much what others have said, I don't have issues with mine falling out although I can see why/how they can, if they are not a snug fit. You get three different size 'adapters/inserts' to achieve the most suitable fit.
You can only pair one bluetooth device at any one time (like most others although some let you pair to two) and telephone conversations only come through the one ear bud.
