I have narrow-to-medium width feet so these fit perfectly. The ear pieces function by use of bluetooth from smartphone or iphone. I?d recommend them to any music lover or musician. Not only a watch but gives me an idea of the weather which combined with the steps counter has given me the impetus to take some regular exercise (the main reason I bought it). - Can pair with multiple devices at the same time. I am 52 and dont have a long torso so it made it a little more awkward to sit with it on. Haven?t had a chance to use it yet, but it looks just like the picture. Pros:- Physical controls, and not just some tap 3x 4x thing like a lot of brands, actual sliding switches for on/off, and volume/skipping- Good sound considering these are mid range price for bluetooth- Solid extending mechanism. Stretched out within a month of use. It has excess material on the back which makes it impossible to wear these with any sort of cropped top or with shirts tucked in.
