What would be good headphones to pair up with a Fiio E18

[TsukiNick]

Chain: Galaxy S4 > E18 and Computer > E18
 
Currently own HD 598s, and Audio Technica M50s
 
But just looking for more headphones, preferably something that will sound a bit better with electronic music.  Probably something with a bit more bass.  No set price range, just looking for headphones to get in the future.

Try a planar magnetic headphone which don't have bass roll-off so excellent sub bass. Can I ask how do the e18's pair with the hd598's?? Does the bass perform well as opposed to un-amped
