I currently use my E4C at work and i feel too isolated when i'm using it, I need an open headphone alternative that doesnt leak sound significantly. So no IEMs and Grados as they are too noisy. No amp so portable use only. My main option at the moment is KSC75, they dont isolate as well so they will enable me to hear things around me, but how much noise do they leak out say compared to the Grados?
