Cannot connect my wired earphones via jack on controller

I dont believe that the headphone jack works over Bluetooth. You would need an xbox wireless adapter for that (and youd get better latency besides).

If the headset is only a Bluetooth headset, then it cannot be connected to the Xbox, as the console does not support Bluetooth. However, you can connect a wired headset to the controller via 3.5 mm audio jack. If the headset can be connected that way, then you will have to connect via the wire.

it said no updates needed- when I connected via usb.

Now, Opened skype, made a call using kinect camera.

camera works fine, I can hear other people via earphone connected directly to my remote. However, they cannot hear me via the earphone. If I remove the earphones, they can pickup the sound from the kinect microphone.

firmware is up to date and this wired option is for one time or every time I use it?

Also, the controllers got 3.5mm jack, does it mean I can use the apple or bose earphones with mic without the adapter?

If you have an older controller then the Adaptor will allow you to use your apple earphones.

If you have a new controller, you don't need the adaptor. They'll plug straight in.

Apple's earphones are standard earphones with a standard jack.

The earphones from your Sony Walkman from 1986 will work.
