They stay put on my earbuds and they are very comfortable in my ears. Pedaling backward gives you the smooth, natural flow of walking. A BRILLIANT product for the money, you will not be disappointed and YES they just STAY in your ear! While the ZSN is again good, there is a shrillness to it, almost like compressing the sound that is unavoidable. Junior Size runs small compared to kids and adult. Mine was peeling up as I took it out of the box. Concludo affermando che il rapporto qualità/prezzo è veramente buono. It just doesnt jive with me, and its not what I ordered. Muy buena calidad de Bose muy recomendables Response rate is quick.
