My giftcard isnt working properly

First in the title you say it's wired then you say it's wireless... For not hearing other players it could be different things. You should try unplugging your headset and plugging it back in.(if it's wired.) If that doesn't work, press your guide button,
go to the right most panel, go to preferences, voice communication, and make sure the voice bar isn't set all the way down. Make sure your mic's volume is also up. I'm not sure about that clicking noise... What's your headset?

I'm also having issues with this same thing tonight. Its probably operator error but i'm gonna mark this post anyway

Try to connect your wireless headset to your console again

The easiest way to connect your headset to your console is to complete step 2 (plug the USB charge cable into the console and turn the console on). If you've completed step 2, unplug the charge cable from the headset and skip to step 4.

Another way to wirelessly connect your headset to your console:

Turn on your console.

Move the mode switch to Xbox (Green) on your wireless headset.

Press the power button on the headset for two seconds. The lights will flash green.

4. After the headset plays the startup sound, press and hold the headset’s connect button for two seconds.

5. Within 20 seconds of pressing the connect button, press and release connect button on your console.

The lights flash green three times once your headset is connected to your console. Your headset will now automatically connect to your console whenever you turn on your headset in Xbox mode.

Note If your headset doesn’t connect within 20 seconds, the lights resume flashing slowly. If this happens, repeat steps 4 and 5. The headset can take up to 10 seconds to connect to your console.

The headset is assigned a position on the ring of light around the console’s power button. Each connected controller is assigned to one of four positions, and each controller can have an associated headset.

Mine too. As well as the YouTube app. Also Xbox Vid isnt working properly on my 360.
