Of course they are tight! They are supposed to stop outside noise. Noc they are not uncomfortable. Noc the silly complaint about the battery compartment coming out is just trivial but it does happen. The sound is outstanding. I scored mine for $250 because the box was scuffed up but never opened so how could I give these winners anything less than 5 stars br brUpdate: I actually prefer the battery easily coming out as this makes charging easier and more convenient. I found these phones are made to be low slung on the ear. Lower than others I have owned. Kind of new to get used to but even the noise reduction works better with what seems to be a better seal when worn lower and very comfortable after wearing for hoursc for my head anywaysc and I do wear glasses. There is a delay when watching a Netflix movie if your tablet (nexus 7) does not support the Bluetooth protocol. I need to use the cord to make the sound not seem like an overdubbed B foreign movie but I must admit if it is a high quality audioc the sound is mezmorizing. I particularly like the even balance as I am not found of the heavy bass like the Bose. Classical music just comes alive. Cross continent jet review to come.
