Im a drummer using an in ear monitor system. I wanted a good case to keep all the compnents in 1 place (body back, reciever, cables, anntanne, wires, batteries and buds). The customizable foam was PERFECT. We were able to make 6 compartments between the 2 foam sheets. I could not be happier. Im sure you can put a wireless mic system in here too. Spend the money and protect your gear.
