Rigid shackle headphones

 

— a shackle made of rigid material that connects both headphones and is located on the back of the head when worn; in some models, it can also serve as a neck mount. The advantage of such a device over the classic headband is that the bow can be used with almost any hairstyle and headgear. On the other hand, in in-ear models and earbuds, this feature makes the headphones more bulky, and in over-ear models it makes sense to use it only with conventional models that are not related to full-size Over Ear. Therefore, as well as for a number of other reasons, nowadays the bow is not very popular.
