If I can't get the fit/comfort sorted out I'll be really disappointed. I'm absolutely sold on the sound and value the extreme isolation. Now it feels like I have pressure issues in one air, like it's clogged or I need to equalize. I can feel it when I swallow.
I usually equalize and release the air pressure inside my ears by slightly pulling my earlobe down, or by pressing the area in front of my tragus when using IEMs (especially the case with Etymotics)
