I have Sennheiser HD280's, and I was wondering how I could make them use detachable headphone cords, like some Monster headphones. This would make it easy to replace the cord if it breaks, and make the headphones easy to store. I'm new to this forum, so I apologize for any stupidity in advance.

You'd have to open them up and solder a 1/8" jack in one of the cups.  Unless you're breaking the cable all the time or want to switch between different cables it would be less work to just replace the cable if it breaks.
