in for one... cant pass up a good deal, hopefully it'll sound decent in comparison to my MC5

Ive been flying almost everyday for the last two weeks(living out of airports sucks), and been using the MC5s exclusively while I also had the RE0s. I much preferred the type of seal/isolation I got from the MC5s and also the reassurance of the handling characteristics of the MC5s over the RE0s...

love the isolation on these and use them as travel/commuter IEMs, but are there higher end IEMs with the same level of isolation or better?
