The frame includes a first cavity, the first cavity being formed by wall portions of the frame. The headphone arrangement includes at least one loudspeaker arranged within wall portions of the first cavity. The wall portions of the first cavity form a first waveguide configured to guide sound radiated from the loudspeaker through a waveguide output of the first waveguide. The waveguide output of the first waveguide includes one or more openings in the first cavity.
