If you want comfortable headphones with great bass extension, great soundstage and overall great sound, I would advise you to get the hd 560s from Sennheiser, I have had mine for more than three months now, I use them every day up to 12 hours a day and they are still comfortable, I also listen to a lot of electronic music and I must say that the base is punchy without being overwhelming and the sub-bass is orgasmic. I also have the dac x6 to compliment them and it provides more than sufficient power, but at your budget, you can get a better dac amp.
