Abstract: A headset includes a speaker, such as a side firing dipole speaker. The headset includes a front chamber that receives sound waves from a first side of the speaker and a rear chamber that receives sound waves from a second side of the speaker. A control leak channel connects the front chamber and the rear chamber. An acoustic mesh may be located within the control leak channel. The speaker configuration is configured to reduce total harmonic distortion of the speaker, particularly in ranges such as 3-6 kHz, while maintaining the broadband efficiency of the speaker.
