Reddit, what kind of headphones should I blow my money on?

Soon, I'm going to purchase over-ear headphones. But I have no clue what is good and what I should avoid. I will be using them while i practise drumming. So I was thinking something that has noise reduction. I need something that covers my whole ear. They NEED good sound, bass especially. I'm willing to pay any thing up to 300, but cheaper is better. Lightweight is preferable, but i can deal with heavier headphones if they stay on my head while I'm moving around and flailing my arms. That's about it. If there is something else I should consider, please inform me in the comments. EDIT #1:If it's an online site. It has to ship to canada. EDIT #2: CORDLESS! that would make me happy but i can deal with a cord
