Abstract
Abstract A telephone handset support device comprising a resilient headband provided with earpads for engaging the ears of the use, and a clip detachably attached to one earpad. The clip detachably connects to the headband and a central opening allows sound from the speaker in the telephone earpiece to pass through the connection to the user's ear. The clip includes a pair of spaced resilient gripping arms which extend generally outwardly away from a base of the clip and towards one another to define a region into which the earpiece of a telephone handset can be placed such that the arms grip around that earpiece. A resiliently mounted lever is urged towards the base and bears on the end of the earpiece so as to press this against the base and together with the gripping arms retains the earpiece in the clip.
