IEM's are more portable and the quality of these I saw on sale is top notch, especially for that price and they are new with warranty and all, so, better to save some extra money and go for it. I owned several portables and all of them have one BIG issue, cable. Have had 2 pairs of AKG k51, on both cable broke within 6 month. My Audio Technica ES7 did much better, but now its on sale, but fully recabled as well. The only pair of headphones I never felt that cable or anything else will be dead soon, were Sennheiser HD25II Adidas edition, but more costly as well.
Anyway, I dont see OP around, becides, many others already mentioned enough to choose from.
