Not trying to thread crap, but I bought a pair of these on impulse and cancelled my order after doing more research. I'm a big Klipsch fan, but a lot of the poor reviews on Amazon have the same gripes...If you MUST have these, I would with a good CC (Amex, etc) if you have one.
These seem to have some poor build quality issues, especially on the left ear bud.
Amazon is not an official klipsch dealer, so no real warranty through Klipsch. Some people had some success anyways, but they were only offered a replacement of Klipsch items for the sale price, not the actual items that broke. (IE $95 paid, $300 headphones broke...offered $95 store credit @ Klipsch)
Amazon's 30 day return policy is pretty much set in stone, so you won't get any help there.
Just seemed like a little too much money + potential risk/hassle for some earbuds.
EDIT - Looks like Amazon is now an authorized online retailer...
