I only had ten bucks to my name today, and I really needed to fix my AKGs... They didnt have the proper solder tip for my old ratshack iron, so I had to buy a new one.. But I needed solder, too.. Wound up buying the soldering kit for $7.99, and using the little sliver of solder that it had in it.
I used the heatsink clip to protect the voice coil, heated up the connection post oh so quickly, splurted some solder on that bitch and they were "better" then new.
