The modular wireless headset includes at least one wearable earpiece and at least one wearable microphone, where the earpiece is physically separate from the microphone. The wearable earpiece is operably to render inbound radio frequencies received from a host device audible. To do this, the wearable earpiece includes, at least, a receiver module, a data recovery module, and a speaker module. The receiver module is operably coupled to convert the inbound RF signals. The data recovery module is operably coupled to recover audio signals from the RF signals. The speaker module is operably coupled to render the audio signals audible. The wearable microphone is operable to convert received audio signals into outbound RF signals, where the outbound RF signals are transmitted to the host device. The wearable microphone includes, at least, an audio input module and a transmitter module. The audio input module is operably coupled to convert received analog audio signals into digital audio signals. The transmitter module is operably coupled to convert the digital audio signals into the outbound RF signals.
