"I have a pair of the MylarOne x3is. Can't comment on the Bijous, but the x3is have been great to me. They come with a hard case and a few different silicone tips (I think that's what they're called...). The only drawback I've noticed so far is that they give off a bit of a hiss when they're plugged into my iPod. I think that's the fault of the iPod, since they don't do the same when I use them with my PSP. Other than that, I highly recommend them over the stock earbuds. Once you get used to isolated sound, it's hard to go back to anything else." - Derek Guenther
