Then go for the second option i mentioned, go to z-reviews on youtube, listen to the sound demo, so you get atleast an idea on what they sound like. The reviews are not credible, but the sound demos are okay..
I would go for DT770, extremely fun headphones especially for EDM.. Although doesn't include detachable cable, it's still a great headphone..
I also advice if possible to try them out first before getting any of the headphones in a local nearby seller, quite sure they will be on display. If it's not possible, try z-reviews sound demo, not the best solution but atleast you have an idea on what the sounds are like..
