Most walkie talkies have a 3.5 mm headset jack that will take just about any audio headset you can buy at Best Buy, Wal-Mart, Kmart, Target or most grocery or drug stores.  Do you use your walkie talkies for traveling together on the road instead of cell phones?  There are a number of walkie talkie manufacturers that make FRS and GMRS radios for campers and the like.  The only issue is the range of the unit.  FRS and GMRS walkie talkies operate in different frequencies that are set by the Federal Communications Commission (FCC).

Walkie Talkies are not the toys you could get with next to no range any more.  Several years ago I represented Cherokee radios in both FRS and GMRS versions.  They produced radios under their own name and the Coleman brand.  The main differences in the two styles are the power, range and frequency they operate in.  These radios are much clearer than even the most powerful CB radios of the past and allow anyone to communicate over large distances with ease.

FRS (Family Radio Service) radios can have a maximum power output of 0.5W by law and work on channel 1-14 as set by the FCC.  Due to its lower power rating FRS radios have a shorter range than GMRS models.  You can improve range by the addition of better antennas and/or transceivers.  When communicating while hunting or camping you may not want to startle wildlife by using a walkie talkie headset that will work on any FRS or GMRS radio.

GMRS (General Mobile Radio Service) radios are more powerful and can achieve greater ranges and are used more by hunters and rescue workers than FRS radios.  Using a walkie talkie headset allows you to conserve battery power when in the field.  Ranges of up to ten miles can be reached from mountain to mountain.
