Not really, no.
My dogs barking, my family talking, my rig humming and whirring and beeping and such, things clanging in other rooms, cars going by outside, all these things interupt my listening unless I crank up the volume. Yes, I love the open sound, (but open-vs-closed is a matter of preference, cannot be definitely said one way or the other), but a semi-open seems like the best of both worlds, IMPO.
