I need help finding a pair of on-ear headphones. Things I look for: good isolation, minimal leakage, portable, and medium size not bulky. Price range is around 50$. I listen to mostly hip hop

I have 300$ so I would like a headphone more close to that amount because I'm willing to spend all of it on a pair I listen to hip hop and some dubstep, I like bass but I wouldn't call myself a basshead I want the pair to be portable and no amp required and good isolation and the less leak...
