Hi!
First of all I want you to excuse me if I make any grammatical mistakes because English is not my first language.
 
Secondly, like I wrote on the title, I need new headphones; I listen to american Rap and R&B music almost exculsively so I need something that fits me perfectly.
I know I have to avoid Skullcandy, Monster, etc but I tried my friend's Beats by Dr. Dre and I didn't like them at all, I listened to two minimalistic produced tracks on purpose to try the bass: Monster by Kanye West ( https://www.youtube.com/watch?v=J3af4Gz4Daw ) and Anti-Freeze by Pac Div ( https://www.youtube.com/watch?v=v-IWe949aFQ ) .
With Kanye's song I noticed a big problem: the drum's bass was like an earthquake (and I liked that) but it literally ate Rick Ross' (the rapper who raps the first verse) deep voice.
With the second one I experienced something similar: I couldnt hear the voices like I wanted but this time it was cause of the heavy bassline not cause of the drums.
 
So, I want something that sounds like an earhquake in my ears when I'm playing minimalistic produced rap or southern rap but I also want to hear the mids and highs because, as a lot of you may know, there are a lot of soul sample presence in hip-hop with violins, pianos, guitars, trumpets, etc and I want to hear that too; I dont want the bass to "eat" them, I want to hear all the sounds with a good bass; and on the minimalistic tracks I mentioned I want the bass to shake my head.
 
Plus, lots of R&B singers are present in hip-hop tracks and I want to hear their voices clear BUT I dont want high pitched voices like Justin Timberlake's to destroy my eardrum, for example in this track (wich has way more instruments than the others I posted) ( https://www.youtube.com/watch?v=2-h-Yt-9ugs )
 
Surfing the internet and reading reviews I found the Ultrasone HFI 580, or maybe the HFI 780 the most referenced to similar cases, but I'm not 100% sure so I wanted to ask you guys! I also read a couple reviews about V-Moda but I know nothing about them, Im a newbie lol!
 
In terms of price I can afford something between 100-160€ (132-210$), and the headhones should be a full-sized closed ones because I listen to a lot of music while in the street/bus/noisy places.
 
Thanks in advance for all the responses!

Ultrasone HFI-580 and 780 would undoubtedly be a better choice than Beats. Another headphone to explore would be the Beyerdynamic DT770, although I think you might want an amp like the FiiO E11 to boost the bass for when you want extra bass heavy sound.

Thanks! Any other recommendations?
And between those 2? are there any significant differences besides price?
 

The 580s have a more of a v-shaped signature--more bass and treble emphasis, although the mids are very clear. The 780s have a warm sound with more forward mids than the 580s. Bass emphasis is not as heavy, but it's good sounding impactful bass and responds well to some bass boost.
