But, the cheap Radioshack soldering iron is not the problem. Only morons would say you can't solder with a $5 iron. I've soldered a LOT with my $5 Radioshack special - and it works FINE.
Here's the advice: USE FLUX!!! I almost guarantee that you were not using it. Melt a tiny bit of solder to the end of the soldering iron (it will stay there until you need it). Then, apply flux to both parts being soldered. Then, touch both parts together and hold iron on it until smokes. Remove iron and you should have a perfect solder. If not, practice a few times.
I think I've seen you say this in other soldering threads, so..
YOU DON'T NEED TO USE FLUX IF YOU ARE USING ROSIN CORE SOLDER.
There, I feel better now.
Correct you are, put a little solder on the tip of the iron, enough to melt maybe 1/4 inch of solder hold this against the wires, when it is hot enough the excess solder will wick up into the wires.
CAVEAT... if you are trying to solder the fabric based flexible wires used in headphones, you're liable to be frustrated as these "wires" are very hard to solder.
Also, make sure the tip is clean. Get a paper towel, wet it thoroughly, squeeze out the excess, and wipr the tip on it quickly in one motion. The tip should be shiney . NOW apply the solder as mentioned above. and continue. Also, you must heat both wires at the same time and with as much surface area of the iron tip as you can manage.
