Voice tubes are the small acoustic tube that channels a headset's microphone pickup close to the mouth: replacement tubes for boom-style telephone and call-center headsets, positioning the microphone precisely for clear pickup while keeping the rest of the boom out of the way. Where call clarity has dropped even though the headset otherwise works fine, a worn or bent voice tube is a common overlooked cause.
Voice tubes are headset-model-specific - order by the exact headset, since tube length, flexibility, and attachment point differ across manufacturers and even across generations from the same maker. For call-center and shared-headset environments in daily heavy use, keep spare tubes on hand; they are a low-cost wear part that fails well before the headset's electronics do. Position the tube correctly after any replacement, since pickup quality depends on distance from the mouth as much as on the part itself. COLAMCO supplies replacement voice tubes for the headset fleets business, government, and education call centers and offices run.
