W40 sounds a bit different than the W4. Same dampers (red, 2200ohm - erji guy was wrong). Same nozzle length. Nozzle opening size is different. I'm very upset. To elucidate, the body and angle are different. Even with the gray Star Tips I get a deeper fit than with the blue (more narrow, longer) Star Tips. Makes for a more forward sound. Oh well.
