I'd recommend the Shure SRH840's. Very neutral headphones with great detail. I especially enjoyed the midrange (best part of the headphone in my opinion) though the bass impact could be lacking. This may or may not be ideal for listening to electronica but I also listen to a lot of the genre and I felt the attack/decay of the bass was crisp and fit in with the music. Definitely handles fast music very well but if you're looking for more bass impact, then look elsewhere.
