I cannot have enough of these phones myself..and have 4 pairs. (Because in the future, Koss opts the right to send KSC-75's in replacement of 35's which are sent in for service, and when all inventory of 35's are is exausted once more)
I sent in a trusty pair of 35's I have owned for over 10 years in for service and Koss replaced with a brand new set of 35's for only the cost of shipping $6..good deal. I forgot how bad the clips hurt the ears at first, and before breaking them in a bit. It is worth it though, they are awesome phones for the money spent, and scale up with amplification too. This is why I have three pairs for backups brand new and waiting active duty in the future.
