These extremely lightweight Bluetooth® headphones are ideal for use during sport. Ergonomically shaped, soft silicone inserts ensure the earbuds stay securely in place in the outer ear. The headphones impress with an excellent sound quality with a rich bass. The earbuds themselves have a magnetic connection, meaning that they stick together when removed from the ear and can be hung comfortably around the neck. This ensures that they won’t accidentally fall and potentially get lost without you noticing. The control attached to the cable, with inbuilt microphone, enables volume control, changing of tracks and a hands-free function for accepted calls. plastic, black, Battery (rechargeable): included, Bluetooth® technology, hands-free function, including usb cable
