- Attach HD 500 BAM: Insert the 3.5 mm jack of the HD 500 BAM boom arm microphone into the headphone's audio input port. Twist the connector clockwise to securely lock it into place. No tools, magnets, or adhesive patches are required.
- Connect to Device: Connect the other end of the HD 500 BAM cable to your desired playback device. If connecting to a computer with separate microphone and headphone jacks, use the included Y-adapter. For devices with a single 3.5 mm jack (e.g., consoles, tablets, smartphones), connect directly. An additional adapter may be required for some smartphones or tablets (e.g., USB-C to 3.5 mm adapter for Apple iOS or Samsung devices).


Operating the Microphone
In-line Controls
The HD 500 BAM features an in-line control unit on the cable for convenient access to volume and mute functions.

- Mute Switch: Slide the switch to mute or unmute the microphone. When the microphone is muted, the red indicator will be visible.

For optimal voice clarity and to minimize background noise, position the boom arm microphone approximately 1-2 inches from your mouth. The flexible boom arm allows for precise adjustment.

- Check that the mute switch on the in-line control is in the 'unmuted' position.
- Verify that the cable is correctly connected to your device, using the Y-adapter if necessary for PC.
- Check your device's audio settings to ensure the correct microphone input is selected and volume levels are adequate.
- Low Microphone Volume or Poor Clarity:
- Adjust the microphone's position closer to your mouth (1-2 inches).
- Ensure the foam pop screen is clean and properly installed.
- Check your device's input gain or microphone volume settings.
- Confirm that the microphone is connected to a compatible device and port.
- Audio Only in One Ear (Headphones):
- Ensure the HD 500 BAM cable is fully inserted and locked into the headphone jack.
