Disclosed is a pneumatic headset comprising a generally C-shaped frame having an upper portion designed to pass over a listener's head and downwardly extending leg portions. A pair of pneumatic sound tubes, each carrying a respective channel of audio information enters and is supported to a free end of one of the leg portions. A first shorter tube of the pair is connected to an earpiece located adjacent the point of tube pair entry into the frame, while a second longer tube is routed through the frame across the listener's head to another earpiece located opposed to the first. To balance sounds between the two earpieces, a venting port is provided in the shorter of the two tubes.
