Side sleeper, I removed ear cup from head strap on 1 side and put it on a crappy blutooth mask/muff for couch where i sleep on other ear. I no longer hear the fridge turn on or ceiling fan motor humm. Even the AC sounds distant. The earplugs are comfortable, but I need to hear my alarm in the morning. You won't need a pillow on your head anymore with this mask and it doesn't smell like petro chemicals out of the box.. Same padding around the eyes this would be 5stars. Very satisfied!
