- On-Head Detection:
The headphones automatically pause audio when removed from your head and resume when placed back on, conserving battery life.
- Using with Consoles:
The 3.5mm connection allows compatibility with various gaming consoles including PC, Xbox, and PlayStation 5. Adjust microphone levels and chat mixers directly on your console's settings.
Maintenance
- Cleaning:
Wipe the headphones with a soft, dry cloth. Do not use harsh chemicals or abrasive materials. For lambskin leather ear pads, use a specialized leather cleaner if necessary, following product instructions.
- Storage:
Store your headphones in the provided carrying case when not in use to protect them from dust and damage.
- Battery Care:
To prolong battery life, avoid fully discharging the headphones frequently. Charge them regularly, even if not in constant use.
Troubleshooting
- No Audio/Poor Audio Quality:
Ensure headphones are charged and properly paired via Bluetooth or securely connected via the 3.5mm cable. Check device volume levels and headphone volume controls. If using Bluetooth, try re-pairing. For wired connections, ensure the cable is fully inserted.
- Microphone Issues:
Verify the boom mic is securely attached and not muted. Check microphone input settings on your connected device (PC, console). If experiencing low gain, adjust settings on your device or through the M&D Connect app. For plosive sounds, try adjusting the microphone's position slightly away from your mouth.
- Connectivity Problems (Multiple Devices):
If experiencing choppy audio when connected to both a phone and PC simultaneously, try disconnecting one device or disabling Bluetooth on the phone if using the PC dongle. The MG20 performs optimally with a single primary connection.
- Headphones Not Turning On:
Ensure the headphones are fully charged. If the issue persists, perform a soft reset by holding the power button for an extended period (e.g., 10-15 seconds).
