Samsung I7500 :: Apple Headphones On Galaxy - Problems With Sound

I've been reading these forums for a while now, and some of these posts are the reason I got a Galaxy myself, imported from Germany

So far I totally love it, but there's this small issue that made me register and finally make a post here.

My previous phone was an Apple iPhone, but I dropped it so the screen broke, and I didn't bother with trying to fix it, so I decided to try something new.
Now, what I loved about the iPhone was the headset/handsfree that came with it. It's the best I've tried so far, and that's why I really wanna use it instead of the crap one Samsung bundled with the Galaxy.

Now here's the problem:
When I use the Apple headset with my Galaxy, the vocals on music doesn't play, unless I press and hold the answer/hang up/shuffle button on the handsfree. And because of this, it does ofcourse not work as a answer/hang up button. The bundled handsfree works as it should, with normal sound, and buttons.

I have no idea if this is a hardware 3.5mm issue, or a software issue, but all I know is the Apple headset works fine on my brother's HTC Hero, which makes me believe it's less likely to be a software issue.

I'm also reluctant of buying another handsfree, incase the Galaxy only works with the bundled one.

Oh, almost forgot, if it's of any use, I'm running the II5 firmware, updated through NPS.
