Can Not Find the SN for XBOX ONE Stereo Headset

I have had my XBOX ONE stereo headset for a little over a month and the mic has stopped working i would like to replace it but they want a SN for it but I have looked everywhere on the headset, the box, and
the paperwork it came with and I still can not find the SN anywhere.

If anyone can help me it would be appreciated

Xbox One Headset Interface Problems

ZigzagLemonHaze,

I can understand your frustration with all the bad luck you have been having. And, for the record, I am not part of the Microsoft staff nor an Xbox customer support employee. But, I can say that we have 2 Xbox Ones and 1 Xbox One S, and 2 of the

Xbox One Stereo Headsets. And, both headsets work well, with and without the
Stereo Headset Adapters, on all our Xboxes.

Headset not working, what am I doing wrong.

I hate to tell you this but the Xbox One console does not transmit game sounds or music through the Xbox One Chat Headset. If you're looking for an Xbox One headset that provides both game and chat audio, you should be
getting yourself an Xbox One Stereo Headset.

To set up an Xbox One Stereo headset, you can follow the steps provided through this link:
