I think 3-4 weeks if I remember correctly.
I had been having repeated cable issues and they suspected it was the headset itself even though a new cable would fix it for 2-3 months before the problem would return. So I had to send the headset to get RMA'd and from when I shipped it to when it arrived back it was somewhere between 3-4 weeks. The tracking on the shipping showed it was being sent in and out of a center in The Netherlands, if that's relevant.
