The KOSS BT540i headphones are lightweight, comfortable to wear for several hours at a time and connect effortlessly to new devices. They come with a carrying case to help you protect your investment while you're on the go or storing them. They also come with a charging cable and an AUX cable (in case you're listening to a device where Bluetooth isn't an option). The controls on the headphones itself are easy to learn and navigate while you're listening to your music (or choice of audio). The play/pause button has a notch on it, so you can easily find the advancement/back buttons (above/below the central play/pause button). Volume buttons are close by but separate, making it unlikely that you'd hit the wrong set of buttons by mistake. I have enjoyed using the pair of headphones for casual listening, as well as downhill skiing (the headphones comfortably stayed in place in both situations). I am very pleased with my purchase and would recommend to a friend!
