Closed back or IEMs for in-room livestream mixing?

Hi all - I mix for a livestream, and due to space limitations, I have to sit in the room where the band is playing... appx 95dB average. I've been using some noise canceling cans, but would I be better off with something like Sennheiser IE400s? I realize I'm always going to have the bass problem (I feel it in my body, so I don't run it loud enough unless I'm very conscious about it), but I'm just wondering which option would be better to reduce bleed. Thanks!
