Sorry lol. No I doubt it because the driver should be more under stress if its technically moving more. With it open its able to breathe and thus move more, producing more bass and a slightly bigger sound stage. I also have my reservations regarding covering the entire IEM. I think some of those removable compartments may not be as sealed as you'd be led to believe. The drivers still may be getting some air just not as much.
mother of Zeus .. Bolt me in the Ass!!! nw they sound like my w4s.. still its pretty veiled as far as " kick drums" exist in songs.. It really opens the mid-range and flatten up the bass a bit.. but still I'm really scared to try this with metal music , i literary can feel the double kick drums trying to Rip off the driver .. hehe! but ill use this method when i feel like "i need more details"
Try Dying Fetus - Reign Supreme album.. i can guarantee that ull get scared!! (",)
