What do I need to talk to friends in very closely with a helmet?
I'd like a way to communicate with my frieinds during airsoft games using headphones, prefferably one (http://airsoft-club.com/shop/tactical-gear/communication/radio-accessories/element-tasc-tactical-headset-tan) but I also believe need to attach to a principal 2-way device. If I buy this (http://www.nextdaypc.com/main/products/details.aspx?PID=8557090&rsmainid=ND0130014) and attach to the headset, can I connect the two? is there any i need to buy? thanks
Those that work well, but you must also obtain the PTT accessory.
