Which headphone would you recommend for modern music, especially hiphop, electronic, pop? (Audeze is too heavy unfortunately)

Go with your intuition. Sometimes I see great deals for the money but the seller presents the item in such a way that I walk away. Presentation and the right information make a big difference for me.

The higher the expense for me, the better the presentation and information have to be.

I'm considering getting the UERM due to the recent drop on MD.  However the Noble 4C also interests me due to its neutral signature and presence on the leaderboard.  I would really appreciate some advice on which to pick.  Which one is more detailed, neutral, and better for everday listening?  Which scales up more?  I listen to mostly non-vocal jazz and other acoustic music as well as some pop/new wave/post punk.  I've read tomscy2000's excellent comparison of these 2 products and I'm slightly concerned if the UERM might be too fatiguing for everyday listening though it seems like UERM performs a bit better in technical ability. 

Am interested in the UERM on MD also, but likely will wait for RMAF
as their digital ear scan is of great importance for a quality fit of these.

Please chime in if anyone found the digital scans not worth it.

You can't beat digital scans for consistency. However, a premo audiologist who does these everday and knows their shit will do better. I personally like my shells to fit a little snugger than the scans allow. They aren't loose at all, I just like a slight more bit of pressure which an audiologist can do.

However, most audiologists don't due these regularly and have very little idea or care as to how to do impressions properly for CIEMs. Unless you have access to a reputable audiologist who caters to musicians and professional bands frequently, I'd go digital all the way. I'm going to guess digital scans will be best for about 95% of the people out there based on that criteria. I've been fortunate to have my non-digital scans done by the head audiologists for UE and Westone. They rock!
