Also the part of these that goes over your ear can get in the way and stop the battery from charging, so you sometimes have to move it move it around to get these to charge. I had never worn them before, but they looked comfortable. These are perfect for little man, comfortable to walk in or outside in. These shoes are very sparkly and cute. I am sorry to say that I do not recommend these. Good job Adidas. The sound quality is also great out of the box. The spice name labels. I use them for my phone and my iPod when I dont want to mess with my wired headphones. I have a pair of Plantronics Backbeat Pro 2s that were $130 and sound quality is noticeably better across the spectrum and those have similar noise cancelling performance.
