To be honest to you, Sennheiser does not make good low-end headphone. They are better off audiophile headphone not consumer. Therefore, CX300 & 400 are definately out of your list 
Where as JVC makes good consumer freindly product! XD JVC HA-FX1X has strong build quality with extreme bass & treble. Between these two is/are the mids that is recessed.
As for Philips side, SHE3580 and cut out the others Philips you had listed :) Check out the review here http://www.head-fi.org/t/561951/philips-she3580-iem-review-how-can-something-sound-so-good-for-10 I like this guy review XD
Now would be SHE3580 VS JVC HA-FX1X eh? lol :D
can't find philips 3580 i think i'll go for 3590 vs sony ex10lp vs jvc vs the others
do you have a specific model in mind ? i prefer normal shape iems, don't like when something's around my ear, so classic style ex10lp is better

Okay,so if you want a natural sounding and has a good punchy bass,I will definitely recommnding you the Yamaha Hph200,it has a nice sound,review can be found here : http://earmass.com/2012/11/25/yamaha-hph-200-not-about-piano-this-time/
already took vmoda m80, but thank you anyway :)




















i would got them if they were available, they look nice, but unfortunately it's way too expensive


) but for my in ear i would like something warm. not too warm, but not flat... and as it's going to be in ear, don't want basses to be overpowered. i'd rather go with quality than quantity in this case, but again staying below the 30 euro (i guess 40-45 $ ? ) if possible :)
