These great shoes are the most comfortable and easy to put on and off shoes I have ever owned. It does slide the case out of the bottom. Once on, they are very comfy and well made. Will climb to 3 if I get a working cable and will consider another bump if it lasts a few months. We tested all three on two different phones. I have to disconnect the BT, then wait for the speaker to reset itself. We actually wired our camera to a separate switch instead of the reverse so that we can use it as a rear view mirror as well. And it hangs on the fence! I would be pretty happy to wear these on a plane, I think they would do really well! I?m saying this because I used to use another brand that?s double this price, and I can compare them.
