I wish I would have got ton the ones with back straps. And, the top kept falling off the top of the last case I bought and the hinge would not allow the case to fully open. They also do not look like real leather. It comes with a variety of ear plug options, I forgot to add the other ear bud options in the pictures. I have a very high instep, this style works well because they dont come up very far on the top of the foot. As for the set up, I think its easier if 2 people work on this. Even during football games--I can hear the piano perfectly and it doesnt disturb my husband watching TV! Esteticamente belle, pratiche da mettere e togliere ma il piede suda molto allinterno. I always tie my tube up to my cooler tube with just regular white rope. I dont particulary like the little nubs on the sole.
