TWS headphones

True wireless headphones

— a special kind of wireless models: headphones (in-ear or in-ear), made in the form of two completely separate devices and not connected by any wire or any other jumper. Each "ear" in such models has its own battery and wireless module (usually Bluetooth). True wireless devices are not only very compact, but also extremely minimalistic: they do not have not only wires, but in general any “extra” details. Their main disadvantage is the high probability of losing one of the headphones; and the capacity of the batteries is usually low.
