Adjust the headband and earcups for a secure, comfortable fit before use.

Recommendations

For best wireless performance keep the line of sight between the headset and the 2.4 GHz adapter where possible and avoid strong sources of interference. Clean earcups periodically and store the headset in a dry place when not in use.
