Personally though I wouldn't, since I'd consider the following:
1. I have no idea what effect the Monster Turbine shell has on the IE8 drivers. That's like getting a pair of Wharfedale Diamond standmounts but with Focal midwoofers for example.
2. I just don't like shells like that - the IE8 shell might be a bit large and isn't as "biological" as shells by Shure, Westone, et al (ie the IE8 was too blocky - it's curved on one side but those corners still press on my ears at angles I didn't like), but shells like that never fit me well at all. They go into the ears straight and then I prefer/need to run the cable behind my ear to minimize microphonics and help them stay in place, but such shell designs always felt kind of awkward in my ears when worn that way.
YMMV though, so if $45 isn't all that much to you (especially if you don't have to deal with import taxes), then I'd say go right ahead. Make sure to add a review thread for reference.
