I'm sorry to hear your "Ultimate Ears TripleFi 10 Noise Isolating Earphones" didn't arrive by the estimated delivery date of December 4, 2010.
In my experience, late packages arrive not long after the estimated delivery date. Please wait a little longer, until December 14,2010 before requesting a refund or replacement. Otherwise, you might have to deal with returning a package.
Please check the tracking details for your package to verify where in the shipping process your package may be.

I'll follow up with you to see if you've received the package after December 14, 2010. If you haven't received your package at that time, I’ll make sure to get a replacement or refund for you.
