So, we found this out by messing with some of our friends and joining their party with modded GamerTags. It is very simple, and comes in handy when you want to hear somebody s*** talk about you after they have muted you.

1. Sign into your normal profile.

2. Start up a party or join a party.

3. Sign into a modded GamerTag that uses the same profile data as the GamerTag you are in the party with. (You need to use a 2nd Controller)

4. Use the 2nd Controller on your modded GamerTag and join the party. You will see your modded GamerTag pop-up.

5. Leave the party on your modded GamerTag, and you should hear an echo in the party. It will sound like you have voice through speakers and headset on.

Any there you have it, you can hear people that have you muted.
