1. Sew the pieces in the appropriate locations onto your own hat.
2. Secure the boom microphone onto your hat. We recommend securing the boom microphone onto your hat in some fashion. If you are using this during extreme sports, you will need to secure the boom microphone in case of hard impacts.
3. Plug in the boom microphone’s 3.5mm audio cable. Make sure the cable is tight and secure. Failure to do so will cause water intrusion into the casing. Any water damage to the unit within the casing is not covered under warranty.
