What's the issue? Do you feel claustrophobic, without totally open-backs?
Hmmm... I have been using mine as my daily driver fo conference calls (which means at least 8 hours per day). They are pretty open... at least I can hear things around me. Maybe not the most open back (my Elex are quite open) but they are definitely not closed in my opinion...
I do a lot of GTA5 RP so I need to be able to hear myself talking normally and it was just too closed off to be able to hear myself well enough and everyting just feels off.
