Apart from the inline bits below, note that the mic on the headset will 
probably suffer from buzz heard at the far end. Bluetooth is probably a better 
bet as it won't suffer from buzz.

For a while there were some free extras while stocks remained, and a headset 
with mic was part of that. This might have been limited to 10-packs

past, but they may now be out of stock.

Bluetooth hands-free kits are cheap and should work. Some cars have these as 
part of the stereo.
