RadTech 13-860 ProCable Shortz Dock Extender for iPhone, iPod and iPad - Black
So pleased... I have been so frustrated with my purchase of the lifeproof case, due to the inability to dock and use other connections.  I almost didn't get this product because someone previously mentioned that it didn't work with JBL.... I had no other options and thought if I needed to, would just get another sound system.  To my surprise, it has been working perfectly with my (several years old) JBL!!
