These are lightweight clip-on headphones with an ear mount and an open design, great for an active lifestyle. They are fixed on the ears with the help of convenient rotating "clips", do not put pressure and are practically not felt even with prolonged use, and the foam of the ear pads provides comfort and allows ambient sounds to pass through — ideal for walks, the city and sports.
