Neutral/fairly balanced IEMs under £400/$500

[AstroBenny]

So I've given up finding a pair of over-ear headphones as my head seems incompatible for xyz reasons. My right ear seems to "stick out" a bit more than the left, causing numbness after about an hour although I definitely wouldn't say my ears stick out a lot..., so I've decided to try the IEM route. I'm looking for something relatively neutral under £400 and will be used for mostly pop/edm. Cheers.

 

Over-ears which have failed me in the past few months on my search...:P

 

-Audio-Technica ATH-M50x - Ears become uncomfortable due to pressing against inner walls of headphone.

-Beyerdynamic DT770 Pro 80 Ohm (Headband hurts for some reason; sensitive head/scalp?)

-Sennheiser HD598C - My most comfortable pair yet; however I'm looking for something more portable as they do not fold and am willing to spend a bit more to get better sound.

-Oppo PM-3 - Same issue as M50Xs, specifically my right ear presses up against the inner wall of headphones which becomes very uncomfortable over long periods of time

-B&W P7 - Headband uncomfortable/head gets sore..(same as DT770 issue)

-Sennheiser Momentum 2.0 - My right ear feels really uncomfortable within the earcup...

-Sony MDR-1000x - Right ear hurts/rubs

-Sennheiser PXC550 - Right ear hurts/rubs
