I take the bus about 2 hours a day too and from work. I currently use a sansa c100 express and some creative ep-630 plugs but I want more sound.
I listen to mostly hip-hop, reggae and R&B and I like bass/deep sounds.
I was thinking of getting the fiido e5/ some m50's and just keep my mp3 player since I hear it's not that bad.
I want some portable headphones that completely silent since this is the bus I'm on and I don't want people complaining of my music.
I bought the MT-21's temporarily but I think I wasted money, it hasn't came yet but I hear it's not completely closed.
To make a long story short, a closed over or on ear portable headphone, a decent amp that cost under 100 bucks.. E5 vs E7 and I prefer some stylish looking headphones that's not huge and takes up half my face like the 202's.
