Yes, I have a set of the silent disco headphones. I use them for my Headphone Outdoor Movie events but could also use them for silent disco if I choose. But my headphones don't have the LED lights which illuminates specifying which channel. So with the clients in my market that would be a must unless there on a budget. The responsibility for Headphones is specified in the contract rider with the client. They hand them out, collect them and make sure each is accounted for. So far none of my headphones have come up missing. The clients I work for are used these type of things. In the College market silent disco is been popular for least the past 5 years. I have been to one of the showcase event for the major companies doing silent disco headphone parties. I found the whole extremely fun and fascinating to watch. Since I had control of the volume in the headphones and what channel I listened actually more enjoyable than listening to a regular DJ blast music. For some reason give these college kids Headphones they tend to dance, sing & act silly as they have fun. Steve, Bryan is my son, he acts like he owns everything. Lol but it's all me. Bryan actually like my father and really doesn't want me to invest in new stuff. Convincing him is the project. Justifications and relisted projections have to be shown. I think Mix might need to have my son standing over his shoulder.
