My new Xbox controller, brand new headset Mic won’t work

I bought a brand new xbox one-s controller so that it would have the 3.5mm input for a mic so that I could talk to my friends. I then bought the xbox one CloudX Stinger Core headset. When I plug the headset into the controller, I get no audio and the mic
isn't recognized. When I go to the xbox controller options, the "Volume" option is greyed out. When I try to start a party, it says "We can't find a microphone for these people".

I have tried updating the controller with the mic plugged in, but as it is a brand new controller, there wasn't an update available. I have also tried restarting the xbox/controller and unplugging the mic, but it still isn't being recognized as plugged
in. I have plugged the mic into my computer and it gets both audio and hears my voice, so I do not believe it is the headset.

I am very frustrated that a brand new controller and brand new headset that I only got because it is Xbox licensed is not working. Any help would be appreciated.

Sounds to me it could possibly be your 3.5mm jack inside your controller. I just had to replace mine. Hope this helps.

Both mics are xbox official headsets and controllers, one of the controllers is a day one edition but just bought another brand new official xbox controller to see if that was the problem. The Mic just randomly stopped working one evening. And yes the
mic symbol is shown in the top right hand corner with no line through it

Thanks for responding. I've tried the suggestions already with no success. The system is an xbox 1s. It is a wired headset connected to the controller. I've tried multiple headsets with multiple controllers. I have sound for both the games and other people in the chat but the mic is not working for any of the headsets, one of which is brand new. Thanks for any help with this.

My Xbox One is 4 days old, and 2 brand new controllers and 2 brand new headsets later, it still doesn't work. Yes, I have everything connected correctly, have troubleshooted everything 5 x over, but no cigar. It excludes me from my multiplayer games because
no mic, no multiplayer chat. No, I don't own a Kinect. The only solution I am hoping on is to throw even more money than $1,160 at my retailer and purchasing a stereo headset adapter which enables the use of the 360's mic or a $120 Turtle Beach headset. That
said, if it's a firmware or hardware issue then it'll make no difference.

Thanks so much! As for the mic issue, one was my razer wireless headset which works great except for the mic, and because of that I bought brand new xbox wired headset and still no mic. Weird cause it says mic is on, but I can't hear my voice, no one else
can, and my recordings don't have my voice either. Was going to buy a third headset but I wonder if it's the xbox itself. thanks anyhow
