Yes. They only come 1 each. But with one you can do driver to passenger.
A Chatterbox FRS Multisport can be had for 149 about anywhere. X-2 goes for about 200 and X-1 for 230+.
After using one it's really handy bike-2-bike. But instead of spending hundreds, you can probably get a couple of cheap FRS radios anywhere and plug in a headset/speaker set. The good thing about Chatterbox is it's all plug and play. You don't have to chase down pieces/parts. But having said that, you don't get everything. It's battery operated (battery was good for 10-12 hour riding days) with an AC charger. A bike/battery cord is exta. You only get 1 headset, so if you want to talk with a pax the additional headset is extra.
You can route a radio (I use a Sirius) and cell phone through it. I ebay'd one and would not recommend these thru ebay unless it's a new unit.
