This cable has a skinny enough jack assembly profile to fit through the provided headphone jack access of any iPod Touch case and easily establish full connection with iPod Touch. This thing doesnt budge. This was an excellent purchase. So I took a shot at JBL, rather than some offshore import brand. Only for small waisted women👎👎 I ended up not using it. Its worth experimenting with this if your hearing isnt brilliant. Once installed it supports the weight of the bike but feels a bit bouncy, I think it is pretty solid and secure but it doesnt really feel that way. I couldnt find anywhere in the description what size the pipe actually is. Das Anziehen klappt für Kinder relativ schwer, es muss genug Kraft haben, um hinten an der Öse kräftig genug zu ziehen.
