Right now I have the Audio-Technica ATH-M50's and I'm looking to upscale to something under $300. The M50's don't have have enough bass for me and I found these 3 headphones to be pretty competitive.
I mainly listen to bassy electronic/dubstep, rap, pop, and some chill/dreamy electronic/liquid dubstep. Feel free to suggest any other headphones.
