Don't like how weak the velcro is on the V2 headband.  

Hi there. Thanks for reaching out. The DJI Goggles 2 Headband currently is only compatible with the DJI Goggles 2 itself. We hope you can get some recommendations on which alternative headband you can use. We apologize for any inconvenience caused. Should you have further concerns, please reach back here at DJI Forum. Have a nice day.
