1. A headset apparatus comprising: at least first and second speakers, each speaker comprising a speaker chamber extending posteriorly therefrom; at least one first tube connected adjacent a first end thereof anterior to the first speaker; at least one second tube connected adjacent a first end thereof anterior to the second speaker; a first outlet at a second end of the at least one first tube for positioning the at least one first outlet at a first position adjacent a user's first ear; and a second outlet at a second end of the at least one second tube for positioning the at least one second outlet at a second position adjacent a user's second ear; wherein the at least one first tube is continuous with the at least one second tube at respective first ends thereof and the first and second speakers are positioned between the first and second outlets on either side of and a distance from the centerline of an acoustic path formed by the first and second tubes such that a tube length between the first speaker and the first outlet is less than a tube length between the first speaker and the second outlet, and a tube length between the second speaker and the second outlet is less than a tube length between the second speaker and the first outlet, and further wherein the tube length between the first speaker and the first outlet is substantially the same as a tube length between the second speaker and the second outlet, and the tube length between the second speaker and the second outlet is substantially the same as a tube length between the first speaker and the first outlet.
