摘要:
There is provided an earphone comprising a hoop band (1) for receiving at least one ear pad (OM). The hoop band (1) has at least two hoop band portions (2a, 2b), wherein at least two of the hoop band portions (2a, 2b) are rotatably connected together by way of a rotary joint unit (5). In addition in the region of the rotary joint unit the hoop band has a spring unit (10) which couples the two hoop band portions together and thus exerts a spring force on the hoop band portions (2a, 2b), wherein the spring force is adjustable by adaptation of the coupling by way of a coupling means.
