Doesn't matter but the joint will be stronger if you put a decent amount on. I tend to use more than enough (whether it be solder, glue or whatever) when I mod things, always been like that since a kid lol.
I just did the shack hack mod with some cheap px100 clone pads (with no holes) as the cloth material over the Magnums was causing discomfort against my ear after several hours of wear. Can't believe I haven't tried this sooner, the comfort level is increased ten fold. The cheap pads are very soft and thin and low density so barely affect the sound (nowhere near the thickness of comfies).
