The true Teva sport sandals keeps your foot secure, allowing you to hike, run, climb, etc. Dont you hate those headphones whose life expectancy is dependent on the stupid wire? I got some stories I could tell you, I can tell you. Two cons to this case is that the size is too big for pockets and the chsrge cable is a very tight fit to my beats. The battery last for three days and the sound is really great. Both cards give you a stable connection. From the review you get the impression these are a real bargain, like getting a £100 set of headphones for £30. Wish it was so I could put it there. Takes two hands and a good amount of force. After reading several reviews I knew to place my old sole which came off without difficulty on top of the new one and traced the needed outline of where to trim off the excess from the new sole. Also very clear.
