Almost 12 inches wide but does not feel too bulky. Mine works with the 3rd option. Noise cancelation seems decent (may have not had it fully plugged in, or my ear canal is slightly bigger, but could barely hear the music playing in the gym at half volume. Well made with nice detail. I love this bar pad. I have another model from Adidas using cloud form and that one is not far better but better than this one. I hope this solution alleviates that headache. You feel like a GIRL again, not just another beige/taupe/gray/charcoal person in a cube. They were tiny (almost like a size 5), returned and got a refund but not inpressed with. Super Schuh mein Freund ist begeistert!
