Stealth 420X - Microphone Not Working

If you can hear game audio through the Stealth 420X headset but the microphone isn't working, please check the following:

1. The Mic Boom is Connected Correctly

The Mic Boom must be plugged into the Mic Boom Jack on the Left Earcup of the Headset. The Left Earcup does not have any buttons or controls; all functional buttons are on the Right Earcup. The 3.5mm jack on the Right Earcup may be mistaken for the Mic Boom Jack; however, that is the Mobile Connection jack intended for use with the included Mobile Cable.


2. The Mic Boom is Plugged Fully into the Mic Boom Jack

After checking that the mic boom is plugged into the correct jack, make sure the mic is plugged fully into the Mic Boom Jack. Disconnect the mic boom by pulling it straight out and plug it back in, making sure to plug it in until you hear a "click". This may take a couple of tries.

3. The Xbox One Recognizes the Headset

If you are able to hear yourself through the headset when you speak into the mic, then the mic boom itself is working properly but your Xbox One may not be detecting the headset properly. The best way to rule this out is a quick power cycle:

1. Power off the headset and disconnect the transmitter from the Xbox One.

2. Power off the Xbox One and unplug the power supply/cable. Leave it for 1 minute.

3. Plug the Xbox One Console power supply/cable back in and power the Xbox One Console on.

4. If you are automatically logged in when startup is complete, log out and then log back in again.

5. Plug the transmitter into your Xbox One and power the headset on.

6. A notification should appear on the Xbox One menu indicating that a headset device was connected.

If the microphone still isn't working, please contact our support team: Contact Support

    If the transmitter fails to respond in any manner, then that may indicate an issue with the hardware itself.

    Please contact our support team for service and replacement options if you have not already.

    The 420X model is not intended for PC use, but for Xbox One. Any use on PC is just for updating, but not for audio/chat use.

    What exactly is being echoed in this case? Depending on the audio issue, it may be something as simple as a replacement part.

    You may want to update your headset, to ensure its on the newest firmware. If you continue to have an issue then you may want to contact our support team, or exchange the product while within your time to do so.

    I bought the 420x and I had a very good time with it until charging it became a little more complicated. In order to charge my mic you would have to hold it a certain way while you were playing and it was a hassle. today I tried plugging my mic in and the charging port on the mic is not working all so now i am left with no way to communicate with my friends at all.

    I can hear game sound fine. Once I enter a party the party can hear me, but I can't hear the party. 

    I have looked at firmware updates, and seem to be updated. I have used this mic without issue for over a year and all the sudden It happened over night. Please send help!

    If your game audio fails, you may want to try the other articles here outside of the mic one, and if problems persist then contact our support team

    @ Jeremy

    Is this happening within a specific game or all games? Does this happen in an xbox party without any game in use? You may want to contact our support team to get into details and possible solutions.
