This application is directed to acoustic chambers that can be incorporated into headsets to improve consistency of sound reproduction between a left and right earcup. Headsets, especially wireless headsets, need to hold many different components within the earcups (e.g., batteries, wireless components, etc.). As earcups are required to hold more components, imbalances between left and right can result. For example, a left earcup might hold a battery, while a right earcup holds wireless charging components. Differences between left and right components can ultimately result in sound reproduction inconsistencies between left and right earcups. Embodiments of the inventive subject matter create consistent acoustic chambers for both left and right earcups so that sound reproduction between the earcups is unaffected by components housed within each earcup.
