- For devices with separate audio (green) and microphone (pink) jacks: Use the included Y-splitter adapter. Plug the headset's 3.5mm jack into the adapter, then plug the adapter's green jack into your device's audio output and the pink jack into your device's microphone input.
Adjust the Headband: Extend or retract the headband to fit comfortably on your head.
Position the Microphone: Rotate the microphone boom to position it approximately 1-2 inches from your mouth for optimal voice pickup. The microphone is flexible and can be adjusted.
Verify Audio Settings: After connecting, ensure your device's audio input and output settings are configured to use the "EKSA H12" or "External Headset" as the default device.
