Headset i could hear but not talk.

The other day I was talking to some buddies and out of no where they couldn't hear me talk. But I could hear them. Ive tried everything that I could think of and it still doesnt let me talk and no its not muted or anything. Please help me. Ive only had the
Xbox and the headset since the beginning of September. I believe that it cant be broken because I can hear them.

I had the same issue a week ago right at the time of the attacks. For days i would get into a party chat and not be able to hear anyone but, they could hear me and i could see they were talking. I had the XO seven headset in and i could hear the game music
and sound effects but i couldnt ever hear my party. All i did was unplug my headset and talk thruogh my kinect im not saying its going to work but it did for me. Hopefully they fix this problem in the new year cuz alot of people have ran into the same problem.

Yes, two people could play online at the same time, both with headsets, and join a party and talk to others, but the two may not be able to hear each other through headsets (because they're on the same console). So both users should be able to hear everyone
else, and everyone else hears both of them, but the two might not be able to hear each other through headsets and would need to rely on hearing each other without microphone/headset.

I hope this helps.

I think it a controller update problem. Yesterday I had the same issue. I could hear everybody in party chat on my headset but nobody could hear me. I tried everything: updated the controller, checked my security setting, and even made sure my NAT was
open. I tried to play a game today and same problem, I could hear everybody just fine, but nobody could hear me. I started troubleshooting it and started up a party chat by myself and when ever I would talk my mic would not light up but my connect would
when I unplugged the headset. I thought either the headset is broke or my controller was, so I plugged my headset into another controller that I never use and started a party chat by myself and it worked. When I would talk and my mic would light up, so I
assigned the controller to my profile and did an update on the controller and the mic stopped working after the update. Same issue as before, I talk, but the mic wont light up. It like it like the update permanently muted my mic for the headset on that controller
after the update.

Wired headset and ive tried with other headsets

tried with another controller

can hear my friends in party

Its weird because my headset allows me to hear myself while talking, and i can hear myself but people cant hear me
