Headset having right- and left-ear sound output units with through-holes formed therein

A headset, comprising:

• a local communication unit which performs wireless communication within a local area;
• right- and left-ear sound output units which output sound received by the local communication unit and which have right- and left-ear cartilage conduction units respectively;
• and a sound microphone which collects sound to be transmitted from the local communication unit, wherein,
• when the right- and left-ear sound output units are worn on right and left ears respectively, the right- and left-ear cartilage conduction units make contact with right- and left-ear cartilage so as not to prevent outside sound from entering right and left external auditory meatus so that directions from which the outside sound comes can be recognized with both ears as when they are not worn, and
• the right- and left-ear cartilage conduction units have through-holes so as not to prevent outside sound from entering the right- and left-ear external auditory meatus.
