The built in ear loops combined with the multiple size tips included make it easy to get a good fit. Once the correct ear tips has been determined and installed these headphones will stay on even while moving around a lot. The buttons are easy to learn and get to. They have good range and work better than most that I have tried. As far as sound goes they get plenty loud and have a fairly flat response. Like many Bluetooth headphones their is a sharp roll off on the highs and low bass. Mid bass is nice and punchy which most people like.
Overall these are great headphones for anyone that plans to use them while working out. They sound great, get plenty loud, and come with a one year warranty.
