I know it's probably been beaten to death in this thread but I would really appreciate a quick few words from anyone without me going through 200+ pages.
I have had a few customs, and this is my take: if it is too tight it will hurt. It might hurt a bit but nothing serious and then you will get to it, but if you feel excessive pressure in a given area, it is better to have it adjusted, because it can seriously irritate you ear. Beyond hurting, too good a seal can create a strong suction feeling in the ear, like on the plane or underwater. If the fit is good, you can easily remove this pressure by moving around your jaw or pulling on your earlobe. If this feeling stays no matter what, the fit is too tight.
No if it is too small, i.e. you have a bad fit that does not allow for a good seal, you will feel it and the sound will be off. The is a good test at Sensaphonics' site. You play two tones, one high and one low, and if the seal is bad, the high tone is louder. Of course, you need to check first that your source plays these tones well.
