I work in an industrial setting control room and have recently started having problems with coworkers not turning the sound down on the radios they use to communicate with other co-workers in the field. The system is relatively old (using Motorola XTL 1500 and Motorola MCS 2000 radios), and some people transmit very loudly over the radio and some very softly. I am looking for a low cost solution to this issue. One solution that I have thought of is a wireless headset with a transmitter beside the current speaker. This would make it so the I wouldn't have to upgrade the entire radio system,
