Abstract
Various implementations include wearable audio devices with counter-bore port features for maintaining a cover on the port. In certain cases, the wearable audio device includes a port that is integrated into the device frame and acoustically couples one or more acoustic cavities to a distinct volume. The device frame has a counter-bore feature proximate to the port for positioning a metal mesh.
