I listen to a lot of trance music, looking for some headphones that arent to heavy while running.

Preferences for IEM's vs on-ears? Circumaural cans will probably get too hot.

Am not really to bothered to be honest mate, am guessing cans would sound better but produce more heat?

I think IEM's are typically more popular, since they're smaller and usually resist vibrations better.
 
Maybe try the GR06? I feel like the over-ear cable routing would help them stay in better, and minimize microphonics. The A151 might be better for trance though, since it's BA drivers are pretty fast. Another great IEM around there is the FXT-90, with dual dynamic drivers.
 
If you're willing to up your budget a little, the popular R50's are another choice.

I use the brainwavz m1 for working out. Plenty of bass on that thing and microphonics are minimal when worn over the ear.
The GR06 is definately a good choice too. Very good sounding pair of IEMs
