jung - Thanks for the recommendation but if I was going to bring some heaphones that couldnt fit in my pocket Id go for another pair of RS1 or something relatively compact like that.
younglee- Did you try getting your impressions redone? Ive heard many reports of problems with initial impressions and although it would be a pain to ship back and forth this is a reality I have accepted before deciding to go with customs, I figure +$100 for impressions and shipping to be safe. And it is exactly for the improved seal/comfort that I wanted to go with customs in the first place, despite them having virtually no resale value.
