First off let me give you some information to make it easier to help me. here it is!
My Headphones i have used, Solo HD, Skullcandy Hesh 2.0, Sennheiser Momentum (currently using)
Source:Deezer,Youtube,CD's( Windows Media Player) on Laptop with my Fiio E17.
Music Genres:EDM,Dance,R&B,Pop,Hip-Hop(a tiny bit)
What i love in a headphone:Bass! i like the thump of chase and status while listening on my momentum's and other EDM music but i also like to listen to female vocalists and other genres for a calm listening experience sometimes, some bands/singers i like are paramore, girls aloud, rita ora, Katy Perry, Steve Aoki, Chase & Status, Hardwell, Eminem and loads others.
I have stuck to looking at the sennheiser range as i love the momentum's dearly as the bass is amazing IMO and still very good natural sounding quality.
As of now i am thinking about either the Sennheiser HD650 or HD700. but i don't know if the HD700 are good as the bass isn't as strong as the 650 or momentum. Any help for me would be appreciated. anything you need to know extra just ask
My budget is upto a MAX of £550 (i also will buy a fiio E09K amplifier to dock my E17 in for high impedance headphones.
ALSO: is there any other advantage to open back headphones except the soundstage? i heard the bass isn't as good for open backed and that might put me off as bass i favour a lot
