I listen to both Zedd and Ellie Goulding myself among a lot of other Kpop, Pop and EDM genres. My favorite two headphones for the said styles at that price point are the Fostex TH600 and Hifiman HE-500. Mainly because of the extremely impressive mid range of the Hifimans. It also has fantastic imaging and I enjoy very layered electronic music like Mind.In.A.Box among others on it. The Hifiman is also a great at a lot of other styles due to being most neutral/slightly dark. It is no slouch with rock for example. For electronic it depends on what your aim is, the Hifiman is not a basshead kind of can so if you are after hard slamming bass can like the Fostex may be better. It is not bass light though with great texture and tactility. The Hifimans main weakness is a wonky mid to treble transition unless you want to due the Jerg Pad mod. It is also fairly demanding to amp. A good inexpensive amp with more than enough power for it is probably an Audio GD product, as their lower models can deliver 2 watts to the Hifiman while including a dac as well. Hard to think of others. Soundstage is rather wide, but on my set up is not all that deep compared to other ToTL models.
The Fostex in comparison has some hard hitting bass depending on the style, quick and engaging. However it is not totally neutral with a slight bit of mid dip. Nothing major but some vocals can sound distant depending on songs mastering effects. The imaging and separation are very deceptive for a closed can, very impressive. I liked the TH600 as much as other 1000 buck open flagships. The soundstage is large for a closed phone, as big as some open cans I've heard. Easy to drive as well. I enjoy Metal on the TH600 and the TH900's
You might also consider the Alpha dogs, but I cannot speak for those having not heard them.
Less expensive but awesome headphones for electronic stuff could include the very very impressive Phillips X1, I myself would love to hear them more.
