Why is my headset causing friends to hear a echo while it's muted?

Hi, I noticed that you marked the answer as not helpful, however I did not receive feedback from you, did you try the last thing I mentioned?

Indeed, the network hardware or firewall may be blocking communication.

Ask your ISP to open the following ports:

Port 88 (UDP)

Port 3074 (UDP and TCP)

Port 53 (UDP and TCP)

Port 80 (TCP)

Port 500 (UDP)

Port 3544 (UDP)

Port 4500 (UDP)

Hello!

I'm an independent advisor and a member of the Xbox Community.

I will be glad to help you.

Have you checked on your own that the same echo is produced even with different remotes and different headphones?

Have you made sure that your controllers are up to date in the "Xbox Accessories" app?

Regards.

Yes I have tried 3 different controllers and even purchased a new headset. My headset still causes a echo in party chat even with the physical mute button toggled on. Friends can't hear me speak, but can all hear themselves echo coming from my headset. I have also updated the controllers with the headset plugged in. I've read somewhere that it could be caused by an issue with my router/firewall settings, but can't find anything to indicate what settings might be causing it.

Is your voice heard in your headset at exactly the same time as you speak, or is there a slight delay from you speaking to you hearing your voice back?

The only reason im asking is that whenever a certain friend of mine logs into a party chat we always get echo, ie I speak and then hear myself a split second later. Its all down to his cheap headset, his TV is muted and yet we always get echo.

The best way to tell if it is your friends fault or not is to leave the party chat tab showing on the left hand side of the screen, and then you speak (while he stays silent), if your friends chat icon lights up green when you hear your echo then its something wrong at his end.
