These headphones deliver crisp, clear, rich sound and simple to use. The first few times I would spend quite a while jiggling them around until the lights indicated they were charging. I like the look of them, but the sole, while cushioned is pretty stiff, there isnt much arch support and the bottoms are a little slicker on my hardwood floor(and I would imagine other hard or wet floors) than I would like in a walking sandal. As you can tell from the photo. However the mic is FAR better, and sounds perfect. I dont know if the person who didnt like the sound quality was using this for music or what. The bluetooth range on this is far better than the speakers priced up to $100 or so. I ordered them in my usual size, 9. Looked material and pic nice buy Like it.
