The rods are tight enough to not swing on their own, but only move if I move them. The only thing I wish was different was that it doesnt stay completely closed. The cross bars are ok but the pieces that go into the rail give too much in my opinion. sound is good and bettery timing is also awaome. seems a teeny wee bit smaller than the left and theres a lot less padding in them. I received this product on time, this product does work fine with my cell phone. Basically using it for showering at the gym. The heels of the sandal have balls where your heel strikes, and the adidas symbol is gone after only a couple months of use. sometimes you also need the helmet. I suppose the size of your ear will determine if it will stay in your ear although they should be designed for all eat sizes.
