A walkie talkie is a handy, portable transmitting and receiving device that makes it easy for two or more people to communicate with each other. While they're also enjoyed as toys by children, they're commonly used for a whole range of professional applications too. Emergency services, security personnel, retailers and event staff all commonly use them. As such, you'll also find related gear and accessories here like security earphones, portable radios, clips, cases and even batteries. A walkie talkie works using the 'half-duplex' principle, meaning that when one person has the transmitter button pressed, the others can only receive a signal which prevents crossed communications.
