The AM800M has housing in gun-metal colour and wood at the back. There are left and right markings printed on each shell to differentiate between left and right. There is a vent on the wood too. The housing is small and I am able to fit the iem in my ears comfortably. The nozzle is straight with metal mesh for earwax prevention.
