A protective case for shipping and for using in place therein a portable sound-playing device such as an audio or video unit, forms a housing resembling a rectangular box whose top side has an opening closed by a cover hinged at its rear edge to the housing for pivoting upwardly and rearwardly to an open position to insert the device, and whose front side has an opening closed by a cover hinged at its bottom edge to the housing for pivoting forwardly and downwardly and then rearwardly and upwardly to a self-storing position parallel to the housing bottom side and in which a protrusion on the cover releasably engages a recess in the bottom side, for unhindered sound transmission from the device via the front opening. The free edges of the top and front covers inter-engage to form a closure seam when the covers are closed, and moisture-impeding edge-sealing formations along the openings and one of the free edges forming the seam seal the covers to the housing and to each other when closed. Resilient shock-absorbing pads adjustably space the device inwardly of the housing interior wall, and an acoustically-transparent screen in the front opening prevents entry of dirt during use when the front cover is self-stored and the top cover is closed.
