They are so comfortable and lightweight, i almost forgot to wear something on my ear! The sound is clear, clear reports is recessed, and its shape is perfect for head nimporte which, large or small, and can be positioned as I prefer. The cord that connects the two headphones is very thin and flexible, I have no problem rubbing around my neck or being bent and being caught by other things. The flatness of the cord, allowing it to remain flat against your neck and not move as easily while jogging or walking. In addition, the clip will keep in place too! The color is very sporty. It is compatible with many smart phones. I really like this, ideal for use on a long walk with the dogs. Perfect !!
