Boy, kids are still mean huh? That need to fit in hasn't gone anywhere either. Buy what you like regardless of how the other kids think.
This reminds me of a valuable life lesson I learned when I was right around your age. My book bag kept breaking on me due to the amount of heavy books and the fact that no one would be caught dead wearing BOTH straps around on both shoulders. LOL. So my mom took me to the Army Navy Surplus store and bought me an army bag that would stand up to whatever I dished out. I was worried about what the other kids would say and if I would be made fun of. My Mom just laughed a little and said to me that I was only as "cool" as I thought, said, and acted. That if anyone would question my choice in bags to laugh back at them and let them know that this was an authentic Army bag that soldiers would wear, and that my bag would stand up to anything and be a lot more rugged than theirs. Also, making sure I let them know that it was cool, and not that I thought it was cool, but that it just was. Well, I had to tell a couple of kids those very things and then we went on winter break. Well, needless to say when we returned there had to be at least 20 kids in my school wearing army bags. I had started my own trend. The Army bags were cool because I said so.
Back to cans. I think you should get a set of closed cans even though I own the terrific HD 558s. They sound excellent but in a quiet environment and others can also hear what you are listening to which might not be desirable.
I really like my Denon DN-HP700s but they aren't the most comfortable especially if you have a small head and/or large ears. They have excellent mids and are efficient and very portable.
The ATH-M50s are among the most recommended set of cans on here and their slightly exaggerated base response might be nice with some of your musical preferences.
The Gemini HSR DJ HPs have made a real big splash on here and are said to compare well with cans costing several times their current price.
Get the 558s or 598s down the road for home listening sessions.
Remember anything you choose is a cool as you say it is!
