[Robeto]

Alrighty, so recently I've been travelling up and down the coast a bit to get to school, and my bag is getting rather full with all of my books along with a laptop. Which has started to force me to leave my godly ATH-M50s at home as they are too bulky to just fit into my bag. 
 
So, I need a pair of small portable headphones or IEMs to take on the train. I need them to be closed as I generally like my beats loud or at least a medium-high volume on the train and I don't want to be one of "those guys" who sit on the train cranking their beats that no one else wants to listen to.
 
I'm a bass lover, but I prefer a more balanced sound listening to some dubstep, electro trance and sometimes rock depending on the day. I haven't owned a pair of IEMs before but from previous experiences I have found them a bit uncomfortable so comfort with IEMS would be great unless I can find a pair of headphones that are super portable and really durable for the train and walking around.
 
As far as budget goes my furthest limit is $100 however I would like to spend much less than that
 
Any help would be greatly appreciated!
 
Cheers,

Balanced, a little bit bassy, comfort, under $100 - MS01, SE215, maybe the GR02 if you don't mind a little more bass. Prefer a warm slower sound or something leaner like the M50s (and tighter)? FXD80s would do well for the latter.
