Replying to Skull Candy warranty

I did search bar and only found buying and selling so if there is a thread on this, i really dont care.  but anyways,
I recently sent in two of my broken skull candies (icons and titans) for warranty replacement (both with right ear failures).  I know it says that it can take up to 4 weeks to process im just wondering if this is how long it actually takes.  anyone have any experience in with this? any help is much appreciated.  thanks
