theres a offer at jaben, C252+bijou+fio amp at 99bucks.
I have bijou 3 too, i'm still burning them now after 60hours, clarity has improved but the highs like a forumers said, are too sharp, listen too long would cause fatigue. But when i initially hear bijou out of the box, it was worst.
Also if you want built quality, don't go for the crossroad bijou, they have high failing rate although there's warranty.
Else u can also consider sennheiser cx300 which is a lower end cx500.
But at $100, there's isn't a whole lot to audition. Earlier this mth had the same budget as u, i got the bijous, still i wan it burned in before i judge it.
