This has been discussed here to death, the Grados are uncomfortable for the majority of the users, you may get used, you may mod them, and later on you get used to them in the best cases, to tolerate them or not varies from person to person, but to state categorically that they are not uncomfortable is another thing, considering that many members here, had gotten expensive Grados, and hard to find Grados and even while they liked the sound, had sold them a few weeks after, just because of that problem...as stated if you found them comfortable consider yourself really lucky...And hwat is worst IMO is that they had done absolutelly nothing to fix that problem and get a more universal approach, other than another piece of foam...
