I'm looking for some good nice closed headphones, with good sound and isolation. I need some suggestions/experiences please?? I'm currently looking at these headphones: Sennheiser hd 280, hd 380 hd 25 sp 1 Shure srh440, srh840?? Beyerdynamic dt770? Heard mixed opinions on these...

I'm new to all this and am looking for a pair of closed headphones, with preferrably a lot of isolation from the outside. I like to listen to rap, hip-hop, soul,j-pop and prefer more natural warmer sound over too much bass. I was looking at the sennheiser hd280 pro but from what I read...
