A neckpiece wearable by a user includes opposing arm segments operatively connected to each other and configured such that each arm segment defines a tethering element configured to removably retain a cable to the neckpiece. The arm segments may be arranged to retain the neckpiece to the user's neck intermediate the shoulders and jaw of the user, such that the neckpiece when worn by the user is not in contact with the user's shoulders and/or is not supported in position by the user's shoulders. An access opening allows the user to don and doff the neckpiece, and is preferably less than 35% of the perimeter of the neckpiece. The neckpiece may include a grasping interface to exert a grasping pressure on the user's neck. The neckpiece may include a physiological sensing element. The arm segments may be formed of wire. A connecting element may detachably connect the opposing arm segments.
