would your gf like the design for v-moda? v-moda is known to a lot of audiophiles for having nice design and sound quality which is better than beats. But do know that most of v-moda headphones have bassy signature so does your gf like to lsiten to house,electronic, dubstep? because the crossfade LP isnt the best pairing for instrumentals and vocals and classical music if thats what she likes.
try out munitio billets? or can go get Beyer XP series!

havnt tried the ckm500 before but the beyer xp has really good value to performance ratio

Beyerdynamic XP series or Final audio adagio II =)

wouldnt know I havn't tried the FA consonance. I've only tried what has been available at jaben D: but if you want my other suggestions you can of course try Headdirect RE-400 and Dunu Topsound Trident, i've personally used the dunu tridents and they are really good entry level IEM's. THe RE-400 on the other hand Clieos sifu highly recommends it saying it is the best you can get in it's price range and if you get it the only upgrade you should go for is top of the line like Westone 4 and above.
