The HS1503 AL comes in a black package with a black protective cover that sports the brand logo, description and image of the iem at the front. At the back of the protective cover, there are specifications and description of the model. There is metal hard case with the brand logo on top in the black package. After unlocking the case, there are the iems, cable, instruction manual, warranty card, a variety of tips [ AET02 (F), AET06 (S+/M+), AET07 (S/M/L), AET08 (S/M/L) ] and a blue leather carrying case that contains a leather cable wrap and a velcro cable tie.
