I cannot connect my xbox controller because the sync button on my console refuses to work.

Hello!

Hope you are well. I'll be glad to assist you.

I'm sorry you're experiencing these issues.

Please try the following steps:

1. Press and hold the Power button on the front of your Xbox until the console turns off.

2. Unplug the power cord from the back of your Xbox.

3. Wait a minute, and then plug the power cord back in.

4. Press the Power button on your Xbox to turn it back on.

5. Try pairing your controller and console again.

I hope the information has been clear, I will be attentive to any questions you may have.

Best Regards.

Is the controller new? has it been working before?

Try to press the sync button on the controller and the Xbox console. More details can be found here on connecting your wireless controller to Xbox consoles:

I bought it used froma friend he had it working on his console but when I got it the sync button was pushed in all the way. Then I opened up the contoller to find the sync button has completely broken off and rattles around in my contoller so pressing the
sync button on my controller is not possible

[quote user="UR MAN SWEENEY"]my xbox wont sync any controllers not even with the charger wire,[/quote]The Play & Charge cable carries no sync data. It cannot be used to sync a controller, only to provide power to a controller.

i can turn my xbox on
with my controller but still doesnt sync.

Power on the console with the power button and let it finish booting. Then power-on the controller with the Guide button. When the controller's lights start spinning, hit the sync button on the console.

i
have noticed that when the green lights spin on the console after pressing the sync button that only three are spinning controller or user two does not light up at all..

It's possible your controller is damaged in some way and can no longer sync. Try
to re-pair the controller using the steps provided above.

Yes, I'm trying to connect my controller via Bluetooth on my Windows 10 PC (It worked before yesterday). When I connect my controller via USB Cable it works fine.

The XBox Button flashing slowly when it's turn on. When I press the sync button to connect via Bluetooth, the XBox Button flashes for 1 second and the controller turn off.

Yes, I have a Turtle Beach Stealth 600 Headset I just purchased and it only connects to the the Xbox One via the Xbox’s sync button. However, my sync button has been broken for years and I am looking for a work around. Are you saying that the adaptor you
linked could be used to connect the headset to the console/controller?
