GBTX-200 – Call Quality & Microphone Troubleshooting

Gemini GBTX-200 – Call Quality & Microphone Troubleshooting

The Gemini GBTX-200 headphones include a built-in microphone and Environmental Noise Cancellation (ENC) to improve voice clarity during calls. If you're experiencing issues with call quality or mic performance, here are steps to help resolve them.

Problem: Callers Can’t Hear You Clearly

• Make sure the microphone is not obstructed by clothing, hair, or accessories.
• Speak directly toward the mic area located on the earcup.
• If using Bluetooth, ensure the headphones are properly paired and connected.
• Try disconnecting and reconnecting the Bluetooth connection to refresh the audio channel.

Problem: Poor Audio Quality During Calls

• Move closer to your device to reduce signal interference.
• Avoid using the headphones in areas with heavy wireless traffic or metal surfaces.
• Restart the headphones and reconnect to your device.
• If the issue persists, test the mic using a voice recording app to isolate the problem.

Problem: Microphone Not Working at All

• Confirm the headphones are powered on and connected via Bluetooth.
• Check your device’s input settings to ensure the GBTX-200 is selected as the active microphone.
• Try using the headphones with a different device to rule out software conflicts.
• If using AUX mode, note that the microphone may not function depending on the cable and device.

Problem: ENC Not Reducing Background Noise

• ENC is active during Bluetooth calls but may not eliminate all ambient sounds.
• For best results, use the headphones in moderately quiet environments.
• Ensure the mic is unobstructed and positioned correctly.

Additional Tips

• The multifunction button can be used to answer, hang up, reject, or redial calls.
• Double-clicking the button while connected via Bluetooth will redial the last number.
• ENC is designed to reduce environmental noise, not eliminate it entirely.
