So, as I was wandering around the forums this weekend, I found this thread. Inspired by one of the posts, I decided to make a high isolation ksc75. So, I ventured to a local sportsman shop and bought these, they isolate for 29db (later that day, I was at Sears and found some that isolated for 30db and were five bucks cheaper, but it was too late. Never rule out Sears). The hearing protectors that I purchased seemed to be perfect as the ksc75 drivers were very easy to put in and they stayed secure. This should be very simple to figure out, but I'll post my process anyway: 1) I took my Kramer-modded ksc75's, took off the clips, and reversed the pads. Before: After: 2) Got my hearing protectors out. 3) I found out that the pads on the hearing protectors are just glued on the housing (The glue was not solid or anything, but it was gooey and kind of sticky). I lifted up about half the pad, then slipped the ksc75 driver through it. 4) Put the driver where you desire and pull the cord so it is firm. 5) Repeat steps 1-4 for the opposite side. Options: -Since you cannot immedietly decipher what driver is left and right, color or mark the screening so you can tell, then maybe mark the outside of the hearing protectors with the same color, or letter, or symbol. You can see What I did in steps 3 and 4. -Once the earpads come off the hearing protectors, they don't stick very well. You may want to use some sort of adhesive afterward to keep the pads down for good. I decided not to do this, because I may want to reverse the mod. Sound: Simply put, the sound does not actually change much, resolution suffers a little bit, and the bass quantity is reduced (this is nice IMO), but the isolation is amazing. They isolate twice as much as my hd280's and were half the price, total. Comfort: The only problem I have with these is the extreme clamping force, but that can be fixed by stretching it over a few books or something. The earpads are very comfy and plush, not sweat inducing like some hearing protectors. Conclusions: I like these better than stock. I could not stand the clips, and the headband mods felt too flimsy. In short, these will be my full size airplane cans.
