Modded KSC75's
Here are my Kramer modded Koss KSC75's on my PortaPro headband. I cut out the entire inside of the grille, put epoxy on the outer edge, covered it with window screen, and then removed the excess screen. I then cut the inner part of the ear pads out to maximize airflow between the drivers and my ears. The combination of the pressure applied by the headband and the open air over the diaphragm results in a tonality that is more balanced than stock in addition to a much more open and sparkly sound. I find that they're also a bit less fatiguing to listen to than they used to be.
