I'm in the market for a new pair of headphones. I can spend up to $300. I don't care about impedance, as I'm getting an amp. I like a lot of bass (I listen to EDM and play video games) and would prefer closed back headphones, but that's not too important. I was looking at the Sennheiser HD8 DJ's, (because of Linus' review) until I read some reviews and forums. I am looking at maybe the DT990 Pro's or AKG 550's or something. So what would you all recommend? Thanks in advance!
