Headphones with headband auto-adjusting

 

— a headband that automatically adjusts to the size of the user's head. Such a headband usually consists of two parts — a hard, usually metal, base, and a soft inner part that fits directly to the head. It is the inner part that is able to stretch, and the user only needs to place the cups on the ears so that it is comfortable — and the headband itself will increase to the desired size.
