MG20 Detachable Boom Microphone Setup and Mic Quality

Quick answer

Attach the MG20 Detachable Boom Microphone by aligning its connector with the headphone's mic port and pressing until it seats fully; the boom should sit just off your cheek, not against your mouth. If the mic feels loose or you hear crackling, reseat it before adjusting any software settings.

Before you attach: what to check on the headphone

The MG20 Detachable Boom Microphone is a plug-in accessory, not a permanent part of the headset. That means the headphone's mic port needs to be clean and free of debris before you insert the boom. A quick look with a flashlight can save you from a connection that seems seated but isn't.

• Confirm the headphone is powered off before attaching or removing the boom mic.
• Check that the mic port is clear; lint or pocket fuzz is a common cause of a weak connection.
• Decide whether you want the Silver or Gunmetal finish before you start, since swapping later means removing the mic again.

How to attach the MG20 microphone correctly

The boom mic only fits one way. Line up the connector with the port and push straight in with light, even pressure. You should feel it stop rather than wobble. Once seated, rotate the boom so the mic capsule sits near the corner of your mouth, roughly a finger's width away.

• Do not force the connector; if it resists, you are likely misaligned.
• Avoid bending the boom at the hinge to force a better angle; rotate from the base instead.
• After attaching, give the boom a gentle tug to confirm it is fully seated.

Positioning the boom for clear voice pickup

Placement matters more than volume settings. The capsule should point toward your mouth but stay off your lips, because direct contact introduces breath noise and pops. If your voice sounds distant to others, move the capsule closer rather than raising input gain.

• Keep the capsule just off the corner of your mouth, not directly in front of it.
• Angle the boom slightly downward so exhaled air passes below the capsule.
• If you wear glasses, route the boom so the frame does not press against it.

Confirming the mic is working in your game or call app

Once attached, open your communication app and select the MG20 as both the input and output device. Many platforms default to a laptop's built-in mic even when a headset is connected, which is why a correctly attached boom mic can still sound like it isn't working.

• In the app's audio settings, set the input device explicitly to the MG20.
• Run the app's mic test or record a short clip and listen back.
• If the level is very low, check the app's input gain before assuming a hardware fault.

Removing and storing the boom mic

The boom mic is designed to detach, so remove it by pulling straight out from the base rather than twisting. Store it where the connector won't be crushed, and keep the port covered if your headphone came with a plug. This keeps the accessory ready for the next session.

• Pull straight out; twisting can stress the connector over time.
• Keep the boom away from keys, coins, and other metal objects in a bag.
• Reattach periodically to confirm the fit still feels secure.

MG20 boom mic setup steps

1. Power down the headphone: Turn the MG20 off before attaching the boom mic so the port is not live during insertion. Checkpoint: the headphone should be off and the mic port visible and clean.
2. Align and seat the connector: Match the boom connector to the mic port and press straight in until it stops. Do not twist or force it. Common mistake: pushing at an angle, which makes the mic feel loose even when it is not fully seated.
3. Position the capsule: Rotate the boom so the mic sits just off the corner of your mouth, about a finger's width away. Checkpoint: no part of the boom should touch your lips or cheek.
4. Select the MG20 as input: In your game or call app, set the microphone input to the MG20 rather than the computer's default mic. Common mistake: leaving the app on its default input, which makes a working mic seem silent.
5. Test and adjust: Record a short clip or use the app's mic test. If your voice is faint, move the capsule closer before increasing gain. Next step: if the mic still cuts out, remove and reseat the boom before troubleshooting software.
