Query: good ear buds that don't slip

I have now purchased 4 of these earbuds. LOVE THEM. I'm on my second pair, bought a pair for a colleague at work and also for my 8 year old. Fit everyones ears and for 2 of us, they never fall out while working out or jogging. Sound is very good for buds - obviously not a substitute for full headphone quality. Price is obviously excellent as they are $20 in store. My kid loves the colours.
