Maintenance

Charging: Use the provided USB-C charging cable to recharge both microphones and the receiver. Ensure they are fully charged before extended use to maximize the 10-hour battery life.
Cleaning: Gently clean the foam windscreen of the microphones as needed to maintain optimal audio quality. Avoid using harsh chemicals or abrasive materials.
Storage: Store the microphones and all accessories in the included metal case when not in use. This protects them from dust, moisture, and physical damage, prolonging their lifespan.

Troubleshooting

Microphone not connecting: Ensure the USB-C receiver is fully and securely plugged into your device. Confirm that both microphones are powered on and their indicator lights are green. For some Android devices, enabling the OTG (On-The-Go) function in your phone's system settings may resolve connection issues.
Poor audio quality or excessive background noise: Verify that the microphone is clipped securely and positioned correctly near the sound source (e.g., near your mouth). Ensure the foam windscreen is properly attached. The built-in noise reduction should minimize ambient sounds.
Short battery life: Make sure the microphones are fully charged before each use. Battery performance can be affected by environmental factors and continuous usage.
