Similarly, canalphones are personal listening devices that are substantially smaller than the human outer ear, but differ from earbuds in that they are placed directly at one end of the ear canal. Both earbuds and canalphones are held in place by friction between the ears and the device instead of the support system found in most headphones. The canal phone may also be held in place by a holder that engages the listener's head.

  The canal phone is also referred to as an in-ear monitor from the state of wearing by the listener.
