I want to connect with headphone enthusiasts in my area. I don't know and headphone fans or friends slightly interested.

Do you burn in your headphones. If so how and how long?

I've been reading about custom IEM's and I'm torn between three models the sensaphonics x2 soft,westone us2, or ultimate ears ue 10 any feedback would be appreciated they would mainly be used for urban mobility and driven by a 5th Gen. Ipod and maybe i'll later invest in a amp.
