Yeah but you probably won't like it. I don't have Trigger yet but what I did on Duster's headset was use a pin vice to drill small holes under each earcup then tie some od green thread between the two earcups and use that as a strap under his chin. From most angles you can't really see the mod and that Headset is solidly on that head. The extra thread I left as a "wire" from the headset that tucked under his vest.

Another option is to use some glue, something that could be removed easily later, to attach the headset to the head.
