This Topstrap headstrap installs in minutes and adds the ultimate control over the balance and weight distribution of the Crystal headset. 
 
This installs easily in minutes and if you ever have found a headset to be too front heavy this completely solves the issue. 
 
This leaves in place the existing strap and cusions already included with the Pimax Crystal but provides you the ability to change the weight distribution and remove most of the contact from the headset that touches the top of your nose. This is a very popular option and is highly recommended.
